Breeders of Airedale Terriers in Finland sent the bodies of dead newborn puppies for examination to the Finnish Food Authority. At Evira, Professor Marjukka Anttila uncovered a problem in the puppies’ lungs. What they found was a defect in the LAMP3 gene that affected the puppy’s ability to breathe due to a failure in the lining of the lung.

After this discovery almost 7,000 dogs that included 300 different breeds were screened for the gene defect. However, it was only found in the Airedale Terriers. The researchers did discover that 1/5th of Airedale Terriers carried the defect.
The good news is that breeders can have a genetic test performed to determine if their dogs have the defect, thus preventing the spread. With total cooperation between breeders, eradicate the defect.
Researchers have said “As the LAMP3 gene has not previously been associated with diseases, in the future its role in the breathing difficulties afflicting newborn babies should be investigated.” This could be another case where a canine issue leads to a cure for humans. If this genetic defect is in 1/5th of Finnish Airedales, it may be in the breed worldwide.
A recent poll by Preeti Malani, M.D found some interesting facts about pet ownership. Pets included dogs, cats, birds, fish, and other types of pets. The physical and mental benefits were evident as has been indicated by other studies, however this study found some interesting information that families as well as an elderly person should consider when deciding if it is a good idea for an elderly family member to have a pet.
We know that the positive reasons to have a pet include but are not limited to:
- Social connections
- Source of enjoyment
- Feeling of being needed and loved
Some of the negatives to consider are:
- Difficulty to travel
- Enjoying activities outside the home
- Putting pet’s needs ahead of their own health needs
- The cost of pet health care, especially for older pets
- Owner health issues that make keeping a pet difficult
- Owner or other family member’s allergies to the pet
- A need to move into a facility that does not allow pets
- The risk of falling because of a pet
In some cases family support will allow an elderly person to keep a pet. If the family agrees to take the pet and care for it if the elderly person must move to a care facility, that will ease the mind of the pet owner and allow them to keep the pet as long as possible.
If the pet owner can arrange for someone to care for a pet while on vacation, this will solve the vacation issue. The pet owner in most cases will be home more than they are away so watching a pet for them may not be a huge task.
If the pet lover cannot have a pet due to financial reasons, they may volunteer at a local shelter or offer to pet sit for friends. This will give them some quality time with pets without the expense. Another consideration if the person likes birds, is to feed the wild birds. A feeder near a window can be a source of joy with little responsibility. Many people enjoy bird-watching which is a year-round activity.

Often if the family will “think outside of the box” a happy solution can be found for whatever difficulties may be present.
In view of the current corona virus pandemic, I thought this study is very interesting and important for everyone to read and share. Jason Stull, assistant professor of veterinary preventive medicine at The Ohio State University, Armando Hoet of Ohio State’s College of Veterinary Medicine and Gregory Langdon of the College of Public Health did a study about cleanliness in veterinary clinics. What they found is interesting. Please read the entire article that is referenced.
For over a month, using a dye only visible with a black light, they studied how thoroughly surfaces were cleaned. They found that it was almost impossible to clean 100% of the surfaces at the clinic. For the current work, Stull and colleagues assessed almost 5,000 surfaces over the course of the study. On average, 50 percent of surfaces were cleaned, with broad variations by type of surface and hospital location. The human-touch surfaces were the least likely to be cleaned such as medical instruments, dog run handles, and computer mice and keyboards.
I believe it is impossible to completely clean everything in your home so that it is germ free. What I do is use a Fresh Air Surround that kills all virus and bacteria. I have used it for years and I believe my family has had less illnesses as a result. I started using it mostly for my allergies since it cleans the air very well. I also notice that it removes any odors that may occur. The real benefit is that it cleans every surface in your house continually. This is something that every veterinary practice, or any other public place can use. I am not suggesting that it should replace regular disinfecting practices, but it is a great addition and easy to use.
By using computers, scientists have discovered the brain activity that precedes vocalization in Seba’s short-tailed bats. This species is important to study since they use a vocal range produced through their larynx to communicate with other bats. What is of interest to scientists is that besides this species of bat, only songbirds and humans use this method.
Since bats use sonar navigation to maneuver and to find food as well as vocalizations to communicate with other bats, their brain activity is an important clue to help understand human vocalizations.
Julio C. Hechavarria at the Institute for Cell Biology and Neuroscience at Goethe University, investigated brain activity preceding vocalization in Seba’s short-tailed bats and were able to identify a group of nerve cells that create a circuitry from the frontal lobe to the corpus striatum in the interior of the brain. When this neural circuit fires off rhythmic signals, the bat emits a vocalization about half a second later. The researchers were able to predict, based on the rhythmic signals, if the bats were about to utter echolocation or communication vocalizations.
According to Dr. Hechavarria, “. . . we know that the corresponding brain networks are impaired in individuals who, for example, stutter as a result of Parkinson’s disease or emit involuntary noises due to Tourette syndrome. We therefore hope that by continuing to study vocal behavior in bats, we can contribute to a better understanding of these human diseases.”
A recent study at the University of Illinois at Urbana-Champaign confirmed that dogs can suffer from hearing loss the same as humans. What is important about this study is it shows that dogs can suffer from hearing loss due to loud noises. This is especially important for people who use dogs to hunt, and dogs that must work around loud noise such as airports and other types law enforcement jobs.
If dogs must work around loud noise, you can get them Mutt Muffs, earmuffs designed for dogs. This will help prevent deafness due to loud noise.
The other causes of hearing loss are disease, inflammation, aging and hereditary (congenital). The breeds and individuals that have the Merle, piebald, and harlequin coloration are more likely to have congenital deafness. For example about 30% of Dalmatians are born with partial to total deafness. There are about 30 breeds of dogs that suffer from deafness due to genetics.
If you plan to get a puppy from one of the breeds that have a high instance of deafness, you can get a Baer test done to determine if the puppy has a hearing problem.
Better breeding can help reduce congenital deafness in dogs. If breeders avoid breeding dogs with the Merle gene, or who are deaf already, in time the instance of deafness will be reduced. In breeds where the Merle gene is not predominant, avoid breeding dogs that have the Merle coloration.
If you notice a change in your dog’s response to your commands, have him checked by your veterinarian to determine that your dog does not have an infection which is causing a hearing loss.
Most importantly, be aware if your aging dog starts to lose hearing, you will have to watch and be careful that your dog does not become injured because he cannot hear the approach of cars and other dangers. With care, a deaf dog or a hearing-impaired dog can life a long, healthy and safe life.
I was contacted by Scruffy Paws Nutrition for Cats to see if I would test and review their products. After reading about the company and their philosophy as well as their attention to specific health issues for cats, I was impressed, and as my regular readers know, I am very critical.
I was offered the opportunity to try a product of my choice on my cat. Unfortunately my cat would not eat the vitamins, she is very fussy. You don’t want to know how many brands of wet food I tried to find one that she would eat along with her Annamaet dry food.
Here is a quote from their site: “Each supplement has been specifically designed for a certain ailment. So instead of a ‘Jack of all trades’ vitamin supplement that may not do any real good… Ours laser target feline conditions to make a real difference. Using our wealth of knowledge and experience, we formulate a nutritional top up that will supercharge the organ health, and help the body heal itself.”
However, I feel that I should share these products with my followers and hopefully you will check them on the Scruffy Paws web site.
In a recent study at North Carolina State University a human adolescent who suffered from a rapid onset of schizophrenia symptoms was found to be suffering from a Bartonella henselae infection which is associated with cat scratch fever.
This person was treated by an array of doctors for 18 months before one doctor noticed lesions that are associated with Bartonella. When tested it was found that Bartonella was the cause of the schizophrenia like symptoms.
This is an important discovery since now researchers are going to investigate other psychiatric disorders and their connection to viruses and bacteria infections. This could lead to cures for afflictions such as Alzheimer’s disease and other medically complicated issues.
Cats that have Bartonella can infect a person from scratching, biting or even licking a person. Strictly indoor cats are less likely to have it. The symptoms typically are flu-like which include:
- a bump or blister at the bite or scratch site.
- swollen lymph nodes near the bite or scratch site.
- a low-grade fever, which is above 98.6°F (37°C) but below 100.4°F (37°C)
- body aches.
Dr. Bradley Smith from Central Queensland University has conducted a study that proves that the Dingo is not a variety of domestic dog, feral dog, or other wild canids such as wolves, but is its own species.

Dr. Smith also says that “Further evidence in support of dingoes being considered a ‘wild type’ capable of surviving in the absence of human intervention and under natural selection is demonstrated by the consistent return of dog-dingo hybrids to a dingo-like canid throughout the Australian mainland and on several islands.”
He goes on to say that there is scant evidence that any canid species are interchangeable with Dingoes even though most canids can successfully interbreed with them.
This is an interesting statement to consider. How does it apply to other hybrids such as dog/wolf mixes and donkey/horse mixes? It also brings into question the theory that dogs are descended from wolves. Is it possible that the ancestor of the dog was a canid sub-species and not a wolf just as the dingo is its own species?
A study by the Swedish University of Agricultural Sciences and the National Veterinary Institute to determine the safety of raw meat diets for dogs found that the raw meat diets contained harmful levels of bacteria for both dogs and humans.
All 60 samples tested contained Enterobacteriaceae species, which are indicators of fecal contamination as well as other contaminants.
The samples were from 10 different manufacturers, and originated in Sweden, Norway, Finland, Germany and England. The raw meat was from at least one source including: uncooked meat; edible bones and/or organs from cattle, chicken, lamb, turkeys, pigs, ducks, reindeer or salmon. Some of the products also included vegetables, vegetable fiber and minerals. For humans the various bacteria found in the raw diets are especially dangerous to infants, the elderly and those whose immune systems are weakened.
Similar studies have been done in the US with the same results and conclusions. Another report states, “Proponents of raw diets for dogs point out that dogs are biologically similar to carnivorous wolves, and claim that the benefits of this type of diet include healthier skin, coat and teeth, more energy and smaller stools, according to PetMD. However, there is very little scientific evidence to support these claims. In fact, most of the scientific research on raw meat diets for dogs shows that they could do more harm than good.”
I have said this before to my clients, dogs and other members of the wild canine family can only eat what is available to them. That does not mean that it is the best diet for them. For example, if wolves and foxes could cook their meat, or if they had other types of food available, they would eat a different diet. If a “natural” diet was that healthy they would live more than the few years that the do. Think about it.
New research by scientists at the University of Nottingham suggests that manmade contaminants found in the home and diet have the same adverse effects on male fertility in both humans and domestic dogs.
This study was done to explore the cause of the declining human male fertility in recent decades with studies showing a 50% global reduction in sperm quality in the past 80 years. A previous study by the Nottingham experts showed that sperm quality in domestic dogs has also sharply declined.
The researchers found that two chemicals, the plasticizer DEHP which is in most homes, found in carpets, flooring, upholstery, clothes, wires and toys, as well as the chemical polychlorinated biphenyl 153 which is banned but still present, even in food to be at least partly to blame.
No studies have been done to see if these chemicals have the same affect on cats or other domestic household pets. What we can do is keep abreast of the latest research and hope that these chemicals will be altered or banned.
