Dogs monitor environmental chemicals

In a study conducted by North Carolina State University and Duke University’s Nicholas School of the Environment, researchers attached a silicon tag on dog’s collars to collect the environmental chemicals that people (and dogs) encounter every day. What they found was interesting. The researchers had the dogs wear tags and their owner’s wrist bands for five days, then they compared the results.

What they found was that there were similar patterns of exposure for both dogs and humans. The contaminants were mostly from the home environment. The researchers tested for three main contaminants, pesticides, flame retardants, and phthalates, which are found in plastic food packaging and personal care products.

The advantage of evaluating the contaminants in dogs is that diseases that result from these contaminants may take decades to show up in humans but only years to show up in dogs. According to Matthew Breed, Oscar J. Fletcher Distinguished Professor of Comparative Oncology Genetics, if scientists can develop ways to link dog disease with these exposures, they may find a way to decrease the diseases for both dogs and humans.

I would like to see the tests expanded to other household pets such as cats. This is an interesting study and using the silicon tag is inexpensive and works well.

CBD for dogs

In a study at Baylor College of Medicine the researchers found that giving dogs with arthritis cannabidiol, or CBD brought relief from arthritis. It has also been used to reduce anxiety in dogs. As an aside, I know that when I give it to my dog before a thunderstorm, he is much calmer. It does seem to take about a half an hour to work but it does help.

Dr. Matthew Halpert, of the Department of Pathology and Immunology at Baylor conducted the research about arthritis and found that nine out of the ten dogs tested benefited from CBD. They also noted that the pain relief lasted for about two weeks after the treatments stopped.

It seems that CBD significantly reduces the production of inflammatory molecules and immune cells associated with arthritis. The improvement in the quality of life for the dogs was documented by both the dog’s owner and veterinarians. Since the structure of arthritis in dogs is similar to humans, the study supports future scientific evaluation of CBD for human arthritis.

However, it should be noted that the researchers found that the effect was quicker and more effective when CBD was delivered encapsulated in liposomes than when it was administered ‘naked.’ Liposomes are artificially formed tiny spherical sacs that are used to deliver drugs into tissues at higher rates of absorption. This means that buying CBD over the counter may not work as well or as quickly.

If you would like to try CBD, talk to your veterinarian first. It is never a good idea to administer any type of medication, natural or otherwise, without first checking with your veterinarian. I know from personal experience that although veterinarians use human medicines and herbal formulas for dogs, the dosage can be radically different for a dog.

Dog training tips 1

Occasionally I will post some dog training tips to help people successfully train their dogs. I started professionally training dogs in the 1960’s and have learned a lot over the years. I hope these tips will help you. Please feel free to contact me if you have questions or suggestions.

Dogs do not speak English, therefore you must SHOW your dog what you want. Your actions speak louder than your words. All of your body language speaks to your dog. Therefore, your ATTITUDE, FACIAL EXPRESSION, TONE OF VOICE  AND MOVEMENT communicate to your dog.

K9 OBEDIENCE TRAINING COVER PRINT

You cannot try and tell your dog that he is not doing the right thing while you are hiding a laugh because you really think your dog’s behavior is cute or funny. Your dog will laugh right along with you. And yes, dogs do laugh.

You cannot ask your dog to obey you if you hesitate in your movements. Your dog will not believe that you are the leader. On the other hand, you cannot bully your dog or physically punish him and expect your dog to respect and trust you. A good working relationship with your dog is built on trust and leadership. This is communicated to your dog by giving commands in a tone of voice that says, “I expect you to do this, no discussion.” Then move in a steady, yet gentle way to convey leadership. Too many people ask their dog to obey, their tone of voice is “sit, will you please sit? Do you feel like sitting?”

Never re-command your dog. If your dog knows what the word means, re-commanding him only teaches your dog that a) he does not have to listen to you; b) he can do it when he wants and c) you are not the leader. For every command there should be an action.

Either you coax the dog into doing what you want or reward him when he does it on his own. If your dog does not know the “sit” command, and you tell your dog, “Sit . . . Sit . . . SIT!”, then make the dog sit on the third sit, your dog will learn not to sit until the third command. He will think that the command is “sit-sit-sit.”

Most people repeat commands to their dog’s because they are being polite (according to human standards) and assume that the dog did not hear the first or second time. I can assure you that if your dog does not respond the first time, and does not acknowledge you, he DOES HEAR you. He is just IGNORING you. Therefore, politeness to a dog translates into “My owner is wimpy, wimpy, wimpy! Why should I listen?”

So, speak clearly and in a direct manner to your dog. For every command expect or initiate an action. Do not repeat commands. Do not hesitate when you move. Show your dog that you are a leader, not a follower.

The two most important things to remember (which is true for people too) are:  1. obedience is not a question of knowing what to do or what not to do, but the ability to exercise self control to do it or not do it. You have to give your dog time and practice to develop self-control. Punishment or harsh training methods should never be used.

2. Your dog knows how to do everything you want him to do. He only has to learn to associate the word or command with the action. For example, before you even obtained your puppy, he knew how to sit, come, and lay down.

How to find a lost dog

Losing a dog can be devastating. A person’s first reaction is usually fear, confusion and panic. However, with a good plan in place, looking for a lost dog can be less stressful and more successful. There are a few simple points to consider when looking for a lost dog. However, prevention is the key ingredient. The most important thing you can do is have your dog micro-chipped and have a collar on your dog with his name tag that includes a way to contact you. If someone in your area finds your dog, they will not have a microchip reader and will rely on a name tag.

1) If you organize a group of people to look for the dog, use all safety precautions so that the volunteers do not become lost as well. Stay in touch using cell phones or handheld radios. The radios can be purchased for a nominal fee at any store that sells outdoor equipment. Radios will work in areas that cell phones may not, however, they have a limited range so be sure that a chain of people can relay messages over distance. Also, establish radio protocol so that one person does not tie up the frequency preventing communication with others. Communication is essential to let the other volunteers know what is going on, if the search is being suspended, or the dog has been found. Because people feel safer and calmer if they know what is going on, this will allow the volunteers to do a better job.

Be sure that volunteers wear the appropriate clothing, (long pants and long sleeves), hats, and substantial footwear. Each volunteer must carry a snack, water, leash, bath towel, bowl, enough water for themselves and the dog, canned cat food or treats and a flashlight. Flashlights are necessary during the day to check dark places.

The canned cat food should have the strongest aroma, (or a similar treat) to lure the dog. Small cans of cat food work well because they can be carried easily and kept fresh.

A bath towel can be used to carry the dog if he is injured, exhausted or to wipe the dog if he is wet or dirty. If the dog is cold, he can be wrapped in the towel.

Volunteers must always work in pairs for their own safety, and in the event two people are needed when the dog is found. A meeting area and time should be established in case communications break down. No one should leave until all are accounted for.

2) A dog that ran away because he is frightened will bolt in any direction, but usually to the least noisy, darkest area. Given the choice of an open field or woods, the dog will go for the woods. If the dog is lost in the city or suburbs, the dog will look for a dark, quite spot to hide after it has run to exhaustion.

Therefore, try to estimate how far the dog will run (this varies with the dog’s size, breed and condition) and add a mile to that. On a map of the area mark where you last saw the dog as the center of a circle and draw a perimeter around that point, based on the furthest point where the dog could be. The circle will encompass the area to start looking for the dog. If you saw the dog run, you can focus in that direction. Be sure to check small dark areas: under porches, stairs, garages, sheds, etc. If you have several people helping to look, have some start at the perimeter of the circle and some from the center. Be sure to look for the dog, never assume that the dog will come when called.

3) If a dog runs away, they usually run into the wind. That means that the wind will be blowing toward the dog, into the dog’s face. Check with a local airport to see what the wind direction was when the dog ran away. Then start looking into the wind from the point where the dog was last seen.  If your dog is a hound, he may follow a game trail. In this case he could travel miles and because he is so focused on following the scent, can get lost.

Dogs who wander away will usually meander along unless they find something to chase or something that interests them. This means that the search area will be smaller. If searching in the woods or a park, look for a game trail and look for fresh dog tracks to see if the dog went that way. If you do find tracks, you will not be able to tell for certain if they are from your dog, so do not give up searching in the rest of the area. If you are searching in an urban or suburban area, listen carefully if neighborhood dogs are barking. Often, they will bark at a stray dog. If you hear a lot of barking in one direction, check that area first.

4) When searching for a dog, travel slowly and make frequent five to ten-minute-long stops. Many people will drive around in a vehicle, calling to the dog. Unless the dog is within a few seconds of your location, he will not be able to find you if you move too quickly. Keep in mind that a dog can hear you calling from quite a distance away. They need time to determine the direction of the sound and then get to it. Wind and other environmental elements can distort the direction of sound (tall buildings, large hills, etc.) making it difficult for the dog to find the source of the sound. By stopping and continuing to call for about five to ten minutes, the dog will have time to find you.

5) When you see the dog, do not act excited and/or run toward the dog. Sit down or stand still and let the dog approach you, even if it is your dog. Sometimes a dog can become so frightened, hurt, or weary that they may not think straight. Their survival instincts may take over, making them more cautious than they would be at home. Depending upon the direction of the wind, you could be downwind, and the dog may not recognize you right away.

Give the dog time to feel safe. Running to the dog may make him run away from you and lose what little trust in humans that he has left. If you feel it will work, you can, at a distance, slowly move so that you are upwind of the dog, and then open the can of cat food, but still let the dog come to you. When the dog comes to you do not try to grab the dog. Let the dog stay there and relax. Slowly pet the dog until you can attach a leash without frightening the dog. If the dog does not want to be caught, you will most likely not be able to grab the dog fast enough to catch him, even if he is next to you.

6) If the dog does not approach you, do not give up. Stay in that area and/or return to that area. You can leave food etc. but do not try to catch the dog.

7) If you leave food for the dog, do not assume that because the food was eaten that it was eaten by the dog. Other animals may eat the food, so continue to search the area. If you can, spread sand around any food that you leave so that you can check for footprints to determine if a dog ate the food. If sand is not available, loose soil will work as well.

8) If you have to search for the dog over a period of time, keep a log of the weather and the location of water sources. The dog will generally head into the wind and seek water.

9) Never forget to advertise. Use every means possible to let the people in the area know that there is a lost dog. Contact all veterinarian clinics, shelters, pet supply stores, and rescue groups. Also post signs in stores with bulletin boards, on telephone poles, especially where children congregate, by public transportation and any other place that you can think of. Be sure to post on social media.  Many newspapers will run a lost dog ad at no cost. Place an ad in every newspaper that is available in your area.

If your dog is not found right away, about every two weeks call everyone you notified, such as the local rescue groups, to let them know that the dog is still missing. This will keep your dog fresh in the minds of the employees.

Always have an up-to-date photo of your dog. If the dog is a breed that looks like others in the breed, a similar picture will do. Remember, the average pet lover will not notice the fine differences between your dog and others of the same breed. So do not panic if you do not have a recent photo. Be sure to expand the area that you advertise in to at least five miles from the point where you last saw your dog.

Keep all your bulletins up to date. If the lost signs that you post look old or weathered people will think the dog was found. When you find your dog, it is important to call all the organizations that you originally notified to let them know that the dog was found. Also remove all your postings.

10) Lastly, never give up. Dogs have been found months after they disappear. Sometimes people find the dog, think it is abandoned and keep it or turn it into a rescue group. This is why advertising is critical.

The amazing ability of dogs to detect scent

In a recent study conducted by the University of Alberta, they determined that a dog could detect fire accelerants such as gasoline in quantities as small as one billionth of a teaspoon.

new ready

The study was conducted to determine the effectiveness of arson detection dogs. To test this the researchers used two dog-and-handler teams. One dog was trained to detect a variety of ignitable liquids, and the other was trained with gasoline. Interestingly, the dog trained on a variety of liquids performed well detecting all accelerants, but the dog trained on gasoline could not generalize to other accelerants at extremely low concentrations.

The reason for the tests was that accelerant dogs will give an indication at a site and when the material is tested in a lab, no trace of accelerant is found.

Those of us who use dogs for various scent work will find this information helpful. The study concluded that a dog could detect odor at one billionth of a teaspoon. In previous studies by Johnson and Johnson, they determined that a dog could detect any scent at one part per trillion.

The variables that must be considered in research such as this are:

The dog’s physical ability to detect odor. Even a good dog will have off days.

The trainer’s ability to train the dog.

The air flow at the testing site.

The age of the material, in other words, how old is the scent source?

And my last comment, if the dog who was trained to detect only gasoline would not generalize to other accelerants at a low level, he was doing what he was trained to do. It does not mean that the dog could not detect the low-level scents. The question that needs to be addressed is do the non-gasoline accelerants have a gasoline chemical that evaporates quickly that the dog would identify at a higher concentration, but at low levels are there other scents or chemicals in the accelerant that are residual which the dog is not trained to find? For example, a dog taught to follow human scent will never follow animal scent. Unless the other accelerants had the chemical composition of gasoline, the dog should not indicate it.

But this is a good study and does give us an idea of the concentration of scent that a dog can detect.

 

A unique custom made storage/tote

Those of you who follow my social media sites know that when I find an especially useful or unique product, or a good book, I like to share it. The other day I went to pick up a chair I had reupholstered and saw this unique product. It is a storage/tote bag made of upholstery fabric. It comes in different colors.

As someone who sews, I liked the use of the upholstery fabric instead of quilting fabric for its durability and substance. It is rigid enough to stand on its own but also has a wire metal frame in the top edge that helps keep its shape. The frame is inside the top edge of the fabric which folds over the frame holding it in with Velcro.

The Velcro is out of sight on the inside of the top edging. You can leave the wire frame in or take it out easily. The storage/tote has one or two pockets on the outside and three on the inside. They have nice size handles.

PENTAX Image

Each storage/tote is custom made by George Gesell my upholsterer. They come in three sizes, 6 x 14 x 61/2” deep, 9 x 18 x 9 ½” deep and 10 x 20 x 10 ½” deep.

PENTAX Image

I can think of a million uses for these storage/totes such as storing kids toys, tailgating, picnicking, pet supplies, traveling, books, a trip to the beach or pool, storage for knitting, sewing, crochet or stationary supplies. They also work well in closets. The handles make it easy to pick them up with vacuum cleaner attachments in them sitting at the bottom of the closet. The small size sits nicely on the back of a toilet with rolls of tissue handy. But use your imagination.

If you are interested you can contact George Gesell at georgefgesell@gmail.com or call him at 410-346-6421 for colors and prices.

Coronavirus structure clue to high infection rate

This is an interesting study and one that everyone should read. According to the study conducted by Gary Whittaker, professor of virology, is the senior author on the study at Cornell University, primates, cats, ferrets, and mink are the most susceptible to the human virus.

According to Whittaker, further research into feline coronaviruses might provide further clues into SARS-CoV-2 and coronaviruses in general.

New strain of canine distemper in wild animals

A new strain of canine distemper has been found by pathologists with the New Hampshire Veterinary Diagnostic Lab at the University of New Hampshire. The infected animals were from New Hampshire and Vermont. The animals infected are fishers, two gray foxes, one skunk, one raccoon, and one mink. This is a distinct strain has not yet been found in domestic dogs. There is no way to determine how many animals are or have been infected that are undetected by veterinarians and researchers.

img039

Symptoms of distemper in domestic dogs include respiratory disease, oral and nasal discharge, gastroenteritis and in advanced stages, neurological disease. If your dog should show any of these symptoms, take it to your veterinarian immediately. It is very important that you get your dog’s yearly shots to prevent infection.

What is important to note is that pathologists discovered that this distinct strain was identified in one raccoon in Rhode Island in 2004. This means that the disease has traveled.

The questions now are how far it will travel and how likely is it that some domestic dogs will catch it and spread it among the pet dog population. Dog owners should be diligent in watching their dogs, especially if they have an encounter with a wild animal.

Pets and autism

It has been fully documented that children who suffer from autism can benefit from living with a pet. However, a new study by Gretchen Carlisle, a research scientist with the Research Center for Human-Animal Interaction in the MU College of Veterinary Medicine has found that the parents of autistic children also benefit from having a pet in the family. Having a pet reduces the stress in parents despite the extra responsibility of owning and caring for a pet.

IMG_0236 email sz

The study goes on to stress that the right type of pet should be selected that will help the autistic child. They suggest that in some cases a quieter cat may be better than an active dog. Certain types of birds or small animals might also qualify as a pet. They also suggest that the child be included in the selection of the type of pet.

As a certified animal behavior consultant, I want to add that if the family decides to adopt a pet, extra care must be taken to ensure that there are no behavioral issues with the pet that could cause an extra level of responsibility for the parents. For any child, being forced to rehome a pet due to behavioral issues after the child becomes attached to the pet is not a desirable situation.

This is why it is important to thoroughly research the types of pets as well as the individual animal to make sure it is suitable for the spectrum of autism the child has. One way to do this is to consult with a qualified dog, parrot or cat behavior consultant (iaabc.org) or an experienced dog trainer if a dog is a consideration.

Petting zoos pose a risk of infection for humans and animals

Professor Shiri Navon-Venezia of Ariel University, Ariel, Israel and colleagues conducted a study to see if there is a risk of infection to both humans and animals. “Extended spectrum beta-lactamase (ESBL) and AmpC-producing Enterobacteriaceae (AmpC-E), which are resistant to a number of commonly used antibiotics, have become a matter of great concern in both human and veterinary medicine, so understanding the likelihood of them colonising the animals is critical to evaluating the risk that may be posed to visitors.”

The researchers also found that if an animal was treated with antibiotics it was seven times more likely to shed MDR bacteria.

Petting zoos are important for educational purposes as well as bringing happiness to both adults and children. However, it is important that petting zoos provide hand washing stations. People who go to petting zoos should wash their hands before and after interacting with the animals.

While this study focused on petting zoos, the same rules should apply to fairs where livestock is housed for show and competition. Many people pet the livestock or walk near their stalls. It is important to note that some of the bacteria comes from the animal droppings, so care should be taken to clean the bottom of shoes before you enter your car or home. If you wear flipflops or another type of open shoe such as a sandal, it would be wise to wash your feet as well. This is critical if you own pets.

If young children are allowed to interact with animals, be careful that they do not put their hands on their faces, in their mouth or handle food before washing thoroughly.
