Hemorrhagic gastroenteritis, (HGE) in dogs

/ susanbulanda / 4 Comments

Recently I had to rush my Parsons Russell Terrier to the Veterinarian ER. He had vomited the night before and seemed out of sorts a little bit, but not unusual for a 10+ year old dog. The only thing different that night was that he did not play his “Ha Ha I can catch you but you cannot catch me” game with Babs our Border Collie. This is a nightly ritual around the living room furniture.

When my husband got up the next morning, Riley had had diarrhea and was listless. This was 5:30 a.m. Larry immediately woke me up and when I looked at Riley I knew he was very sick. We immediately took him to the Veterinary ER.

We spent the morning at the ER and then took him to my regular veterinarian when they opened. The diagnosis was Hemorrhagic gastroenteritis, (HGE). Because I had caught the disease before it had progressed and got Riley to the veterinarian right away, he was able to come home that afternoon. By the next day he seemed like his old self but still had a few days of medications and a bland diet left to go.

HGE is a disease that causes sudden vomiting and bloody diarrhea. The symptoms are severe and can be fatal if the dog is not treated right away. The progression of the disease is so fast that a dog can die within 24 hours.

Although it is common in young adult dogs (Riley had it when he was one to two years old) it can show up in older dogs as I found out. It is most common in small breeds but it can affect any dog of any size.

What is important to know is that the disorder occurs very suddenly and without warning. The main symptoms are vomiting and bloody diarrhea which is often bright red, like fresh blood. Some dogs have painful abdomens, they will not eat, can have a high fever and are listless. In Riley’s case his temperature dropped to 98°F.

The exact cause of HGE is unknown but some suspected causes are:

  1. Eating non-food items
  2. Eating different foods that the dog is not used to
  3. Immune-mediated disease
  4. Various toxins
  5. Pancreatitis
  6. Stress (note that stress can be good stress such as excitement about playing, as well as bad)
  7. Anxiety
  8. Hyperactivity
  9. Allergic reaction to food or airborne substances
  10. Intestinal parasites and bacteria

Riley had a battery of tests and X-rays to rule out other causes of his symptoms. Some of the tests that a veterinarian may use could include a CBC, analysis of the blood, urinalysis, X-rays, clotting tests, fecal test, ultrasound or gastrointestinal tract exam.

Treatment must include IV fluids, antibiotics, and in some cases gastrointestinal protectants, anti-vomiting medications and perhaps plasma or colloids. The most critical treatment are IV fluids which must be given right away. If not, the dog will most likely die.

Since there is not clear trigger for HGE, it is hard to prevent it. What I learned is that while a younger dog can tolerate some of the causes, an older dog may not. That means that an owner with an older dog must be more careful. One of the things that my veterinarian stressed is to only feed a high-quality dog food, which I do. Dog foods that are available in the supermarket or discount stores are not high quality. I personally like Annamaet and Wysong foods. Even if you feed your dog a high-quality food, you must also be careful with the treats you give your dog. Poor quality treats may trigger HGE as well. Another important preventative measure is to be sure to give your dog regular heartworm medication as well as tick and flea prevention.

Always keep the phone number and address of your emergency veterinarian clinic handy as well as your regular veterinarian. Some emergency clinics are only open at night and weekends instead of 24 hours. A dog who is being treated for HGE must stay at a clinic under supervision until they are well enough to come home. The total treatment can be costly, Riley’s bill came to over $1000 for both clinics combined. If your dog is young, it might be a good idea to get pet health insurance, many plans are reasonably priced. This is a very good idea if you have a working dog who is more likely to be injured or get sick.

Some people may see the early signs of HGE and feel that the dog will get better in a day or so. What I hope my readers learn from this article is that you cannot wait. It is much better to be safe then have your dog die. The longer the dog suffers from HGE the less likely they will survive due to complications that HGE causes.

Dogs help children with a rare and severe form of epilepsy

Although Lafora disease only affects about 50 children worldwide, it is a deadly form of epilepsy that is common in Wirehaired Dachshunds.

(photo is not a Wirehaired Dachshund but it is cute!)

Many Wirehaired Dachshunds suffer from Lafora, and because the disease is the same in children as it is in dogs, veterinarians and human neurologists have teamed up to study the disease.

Dr. Clare Rusbridge, Reader in Veterinary Neurology at the University of Surrey and Chief Neurologist at Fitzpatrick Referrals, have been working with specialists of Lafora in children at The Hospital for Sick Children in Toronto and have identified a canine gene mutation that causes Lafora in dogs.

They were able to study the progression of the disease in dogs so that they could identify its early stages in children. By understanding the progression of the disease, scientists will be better able to identify it sooner in children and eventually find a cure.

The plus side of these studies is that over the past five years, with the help of the Wirehaired Dachshund Club and Dachshund Breed Council, breeders have tested breeding stock and as a result, have reduced the number of litters that are at risk of having Lafora from 55% to under 5%. Hopefully the continued research will benefit humans as well.

Almost half of Pugs, French Bulldogs and Bulldogs suffer from Brachycephalic Obstructive Airway Syndrome (BOAS)

Short nosed or Brachycephalic dogs such as Pugs, French Bulldogs and Bulldogs suffer from Brachycephalic Obstructive Airway Syndrome (BOAS) which can cause health problems, breathing difficulties and even death. Veterinarians have conducted research to try to determine if there is a way to predict which dogs will suffer from BOAS, (almost half the dogs in these breeds are affected). By determining which dogs will have BOAS, breeders can try to eradicate it from the breeds that suffer from it.

In 2015 researchers at the Royal Veterinary College, University of London determined that dogs whose muzzles were less than half of their cranial length and dogs with thicker necks were more likely to have BOAS. However, they did not feel that this was a reliable way for breeders to select dogs for breeding.

More recently a new study by researchers at the University of Cambridge tried to compare neck girth with chest girth and muzzle length to see if that could predict BOAS. However, they found that it was not easy to measure dogs and it was not reliable. They did suggest that breeders should not use dog with very short muzzles, wide faces and thick necks for breeding.

Dr. Nai-Chieh Liu one of the researchers suggested that breeding for open nostrils is most likely the best and easiest way to improve these breeds. Researchers are going to try to find a genetic marker for BOAS to help improve  Brachycephalic dogs to improve breeding programs.

People who own one of these breeds should have their dogs checked yearly for difficulty breathing even if the dog appears to be OK.

According to the latest research in the UK, GSD’s are most likely to die from complications due to musculosketetal disorders.  Almost a half a million GSD’s were studied by the VetCompass™ Programme at the Royal Veterinary College.

The dogs surveyed came from 430 veterinary clinics. They found a total of 263 disorders, the most common were, inflammation of the ear canal (7.89% of dogs), osteoarthritis (5.54%), diarrhea (5.24%), overweight and obesity (5.18%), and aggression (4.76%).

According to Dr. Dan O’Neill, from the Royal Veterinary College, GSD’s have the second highest number of health disorders, with Great Danes being the first.  According to the report, GSD’s suffer from an abnormal formation of the hip joint, cancer, and degenerative spinal disorders which he feels is a result of breeding for cosmetic features such as a sloping back and lower hindquarters.

This is the first study, which included 17 different breeds, whose goal is to help breeders improve the health of their dogs.

It would be interesting to see how the study compares with the health of GSD’s in other countries.

High cholesterol in dogs may help fight bone cancer

/ susanbulanda / 2 Comments

In a recent study at Oregon State University by Haley Leeper, a veterinary oncology resident at the OSU College of Veterinary Medicine as well as Craig Ruaux and Shay Bracha, colleagues of Leeper in the Department of Veterinary Clinical Sciences, and Austin Viall of the Department of Veterinary Pathology at the Iowa State University College of Veterinary Medicine showed that higher cholesterol seemed to help dogs survive bone cancer longer.

They found that dogs with the malignant tumor, osteosarcoma, which is also diagnosed in humans, typically afflicting teenagers and young adults, that had high serum cholesterol lived on the average of 200 days longer than dogs who did not have high cholesterol.

Researchers plan to study why the high cholesterol helped dogs survive longer and perhaps learn ways to cure this type of cancer in dogs and humans alike.

I personally hope they come up with a cure for bone cancer, I lost my beloved Rottweiler to bone cancer many years ago.

The gene that causes epidermolysis bullosa in the Central Asian Shepherd Dog and Humans has been identified

/ susanbulanda / Leave a comment

The genetic defect that causes hereditary blistering disorders of the skin, known as epidermolysis bullosa, in both humans and the Central Asian Shepherd Dog has been identified as being the same. The defective gene causes the skin to be easily damaged resulting in abrasion and blistering. There are four different types of the disorder, simplex, junctional, dystrophic and Kindler syndrome.

The defective gene causes a lack of collagen between two layers of skin.  Without the collagen, the skin will blister.

Thanks to the gene researchers at the University of Helsinki, Marjo Hytönen, a member of the research group led by Professor Hannes Lohi and pathological tests conducted by the Finnish Food Safety Authority Evira, the defective gene was confirmed.

As a result, tests can be conducted on members of the Central Asian Shepherd Dog allowing breeders to select only those dogs that do not have the defective gene as part of a breeding program. Hopefully, researchers will be able to find a cure for humans.

New discovery may help cure dogs and humans with heart disease

/ susanbulanda / Leave a comment

Myxomatous mitral valve disease (MMVD) and congestive heart failure in older dogs is age related and often affects small dogs. MMVD is the most common cardiac disease in dogs. Once a dog has congestive heart failure they are only expected to live between one and nine months.

img092

Researchers at the Cummings School of Veterinary Medicine at Tufts University have discovered biomarkers in the extracellular vesicles of dogs with MMVD in the form of microRNA (miRNA) which circulate in the blood and urine. What is exciting is that this is the first biomarker based on extracellular vesicles in a veterinary disease.

MMVD is similar to mitral valve prolapse in humans, so this finding can eventually benefit humans with heart disease. While further research is needed, this is a wonderful finding that has potential to help monitor the progression of the disease as well as lead the way to developing treatment for both humans and dogs.

A new study about co-sleeping with your pets

/ susanbulanda / 2 Comments

A recent study examined the practice of sharing a bedroom or bed with a dog. While the authors suggest that more research is needed, they compared sleeping with a dog to the practice of sharing a bed or bedroom with a child.

scan0022

The current concern about co-sleeping with a child focuses on the child suffering from poor health, impaired functioning, developing problematic behavior and sexual dysfunction. However, there is not enough evidence to determine if there are negative effects of co-sleeping with dogs or other pets.

According to the study, the benefit of co-sleeping with both pets and children are saving resources, keeping warm, and feeling safe. It is a practice that has been going on for many years.

When it comes to sharing a bedroom with a dog, as an animal behavior consultant, I recommend letting a puppy sleep in a crate in the bedroom to help the puppy bond with the family and feel safer in a new environment. After the dog is trained and under control, it can be allowed to sleep on the bed with a family member. However, if the dog is not trained it can become possessive of the bed or other furniture to the point of becoming aggressive if a family member wants to move the dog. Whether it is good or not depends on many factors, including the dog’s temperament and the owners ability to train and control the dog.

Rat lungworm can cause meningitis in humans and animals

/ susanbulanda / 5 Comments

Rat lungworm, a parasitic nematode, has been found in five Florida counties so far. The lungworm depends on rat and snail hosts to complete its life-cycle. To become infected, both humans and animals must eat the snails or infected frogs or crustaceans.

Although the fatality rate in infected humans is low, the parasite can cause eosinophilic meningitis if it dies in a person’s brain which can lead to a coma and/or death.

Adults who become infected suffer from headaches, stiff neck, fever, vomiting, nausea, and paralysis. Children suffer from nausea, vomiting and fever.

Animals that are infected can get meningitis, weakness in their limbs or even paralysis, neck pain and central nervous system problems.

Prevention involves washing produce since snails can be very small. Children should be taught not to handle or eat snails. If they handle a snail they must wash their hands. To prevent infection in pets, check their living area including watering troughs or dishes, and watch to make sure that your animals do not eat snails.

Why do dogs chase their tail?

/ susanbulanda / Leave a comment

Seeing a dog chase his tail can be very funny. But why do they do it? There are a couple of theories, although until dogs can talk and tell us, we will never know for sure.

Puppies most often are the ones who chase their tail. It is almost as if they see it for the first time realize it is there and decide it is a toy to be caught. If their tail is long enough, they may catch it, but if it is short they will whirl around until they are tired, never actually catching their tail. When a puppy realizes that the tail is theirs, or they cannot catch it, they will often give up the game. In some cases, they will chase the tail of other puppies. This can be a way for them to expend their energy.

smiling-riley

If a dog has never chased his tail and suddenly starts to and does not have a playful attitude, a trip to the veterinarian is in order. A dog may chase their tail due to skin problems, eye problems or neurological issues.

Some dogs chase their tail because the owners think it is funny and laugh. Dogs know when you are laughing at or with them, and yes, dog do laugh. https://www.psychologytoday.com/blog/canine-corner/200911/do-dogs-laugh

A happy response from an owner is a form of reward or encouragement for a dog and a dog will use what works to get attention from the owner. An example of this is a young Collie pup who was deaf and used to get underfoot. Family members would accidently step on her front paw. When this happened the person who stepped on the dog’s foot would bend down and fuss over the dog, rubbing her foot. After a while the dog learned to limp to get people to rub her foot, even though no one stepped on her.

It is possible that a dog will chase his tail because he is anxious. Physical exertion does relieve anxiety and chasing a tail may be one way a dog deals with anxiety. If this is a possibility the owner should look for other signs that the dog is anxious, such as trembling, panting, hiding, or looking generally upset. Owners are good at reading their dogs and can tell when the dog is happy or not.

Although it is not that common, some dogs suffer from a form of compulsive disorder which is really compulsive behavior http://www.petmd.com/dog/behavior/evr_dog_behavior_compulsive_disorder

and may chase their tail until they are exhausted. If this is the case the owner must consult a certified animal behavior consultant to help cure or control the problem. Left untreated the behavior can escalate and become a danger to the dog. To find a good behavior consultant go to: http://www.iaabc.org

The best thing a dog owner can do is to provide enough exercise for their dog so that they expend their energy in a healthy manner. Some dog owners have difficulty determining how much is enough. This depends on the type and breed of dog. Little dogs do not need as much room to run to satisfy their needs. The larger the dog the more room they need. Dogs that are bred to work typically need to cover a few miles in order to have enough exercise. The age and health of the dog is a factor as well. For a healthy dog, enough exercise is when they flop down and want to sleep. They may need this type of exercise a few times a day. Typically, the morning and evening are the times of day most dogs want to be active. With some planning and research, we can keep our dogs happy and healthy.
