Canine Heart Disease

Canine Heart Disease

It has often been said that our dogs are "all heart" and fortunately most of these hearts are working beautifully, but we do occasionally examine patients whose hearts are not quite working up to par. In fact, according to the American veterinary medical association, about 1 in 10 dogs nationally, or about 4.2 million dogs have some form of heart disease. This disease can be a heart valve disease which we see more commonly in the smaller breeds, or be a heart muscle disease, called cardiomyopathy, which we see more commonly in the large and giant breeds.

Some of these diseases are inherited, and can be detected very early on, while others develop later on in life, and can sometimes be difficult to detect. That is why it is very important to examine the heart very thoroughly as part of all routine exams-especially for middle aged and older pets. With valve diseases, we will often hear a murmur as the first sign of a problem. With the heart muscle diseases, or cardiomyopathies, the earliest signs might only be detected via radiographs, an ECG, or on an echocardiogram, which is a special heart ultrasound study. There are some new blood tests for heart disease on the horizon which may soon change the way we diagnose these problems. Because heart disease can occur later in life, routine monitoring is always important, and a clean bill of health last year doesn't guarantee the same this year!

Since both valvular heart disease and cardiomyopathy can lead to heart failure, early detection and treatment is essential to help slow the progression of the disease. Treatments vary based on the severity of the disease and the patient's overall health, so a thorough physical exam, complete with blood and urine analysis, is always recommended prior to treatment. When caught early, before the onset of noticeable clinical signs, treatment may simply involve a special diet with or without one or two daily oral medications, and, of course, frequent follow-ups. As the heart disease progresses, other medications may be indicated, and in cases of advanced disease, a referral to a veterinary cardiologist-an animal heart specialist-may be in order.

The good news is that there have been many advancements made in the treatment of canine heart disease-there are even dogs walking around today with pacemakers! When diagnosed early, heart disease is much more treatable, which allows this important member of your family to enjoy the longest, best quality of life possible.

Puppy Potty Training
You have just adopted a new puppy, but now how do you potty train your new pup? If it is crate trained when you get it, then it is probably accustomed to going on newspaper. You can place some newspaper outside and bring your dog out to it. Make it understand that you want it to go outside to go to the bathroom. While it is in the house, keep it confined to a small area and never lose sight of it. Only correct its behavior when catching it in the act. A dog will not understand reprimand if it is after the fact. You must keep it confined so it learns where it sleeps. When a pet considers an area “where it sleeps,” it will not relieve itself there if at all possible. Slowly introduce it to new areas of the house while keeping extra close attention to its behavior. Keep your dog crated or outside when you are not home to monitor it. It is much easier to teach a puppy from scratch than to try to break bad habits that it picks up without supervision

Does Your Pet Make You Sneeze?
Do you suffer from allergies and are considering getting rid of your pets? Well have you tried this yet? Try keeping your pets out of your bedroom and use air purifiers in the rooms you spend most of your time in. Use a HEPA filter in air purifiers and vacuums, as well as on your heating system. Try dusting at least once per week using a damp cloth. Be sure to wear an allergy mask while cleaning. One last word of advice: Don’t run ceiling fans; they can cause allergens to become airborne and circulate throughout your house.

How to Stop Begging
Many of us have begging dogs, but there is a simple solution to stopping the behavior. Try to keep your dog occupied during dinner. Either feed it at the same time that you eat, or give it a toy to keep it occupied. Beyond that, ignore your dog if it should beg while you are eating. And most importantly, do NOT give in to its persistence. Remember, your dog learned this behavior at a prior time because it begging worked.

Table Scraps...Bad For Your Pet
While half of pet owners admit to feeding their cats directly from the dinner table, experts warn that this can be detrimental to their health. Table scraps can lead to overweight cats if not carefully measured. Or worse, certain foods such as avocado, raisins, grapes or onions can be toxic to pets. You can check with the ASPCA online to see a list of other poisonous foods.

Horses and Dehydration
When horses have lost too much blood or fluids from dehydration, they enter a dangerous state of low blood volume or hypovolemia. Veterinarians administer saline solution along with other fluids to restore blood pressure and volume to normal levels. A horse in danger will present with a rapid heartbeat, weak pulse, and cold extremities.

"Remember to Have Your Pet Spayed or Neutered"
I think Bob Barker said it best, “Remember to have your pets spayed or neutered.” I didn’t understand it back then, but it turns out he was right. While neutering will calm a hormonal male and eliminate testicular cancer, spaying eliminates any chance of pregnancy or uterine cancer and significantly reduces incidence of tumors of the mammary glands. And by the way, because they are low risk and extremely common procedures, the price is right. .

Senior Pets
More than 50 million U.S. households are caring for aging pets. Dogs are considered to be seniors by age 7 or as soon as 3, in extra large breeds. As they age they can become anorexic and may refuse to drink liquids as well. Senior pets require special care to remain at their optimum health. Monthly home exams become especially important in senior care. Semi-annual veterinary exams are a must. Your pet’s weight, eating habits, lumps, bumps, teeth, and gums should all be monitored for any negative changes. If you do find changes, consult your veterinarian.

Cracked Hooves in Horses
Cracks in the hooves are a major cause of lameness in horses. Veterinarians say that quarter cracks are usually accompanied by a sheared heel. Both need to be addressed in order to heal the horse, which can be a lengthy process. The overloading of the heel causes compensatory changes in the hoof and takes time to correct back to its normal structure. It is biomechanical dysfunction that causes the overloading in the first place. Regular examination including chiropractic can help prevent the imbalance in the hooves.

Dog Digestion Problems
A dog with digestive problems may be suffering from a more specific ailment. Pancreatitis can cause diarrhea, vomiting, and lethargy. A thorough examination and lab tests can confirm the diagnosis. Although pancreatitis is not curable, medications can help to minimize symptoms in canines. Any dog that is vomiting frequently, having diarrhea, or is losing weight for no apparent reason, should be examined by your veterinarian.

Brushing Everyday
When it comes to pet’s teeth, daily cleanings and regular professional cleanings are best, and not just any professional. Dental hygienists and such are certainly better than what pet owners can do, but they are still are not up to par with veterinarian techniques. To properly clean your pet’s teeth, animals need to be sedated. Whenever administering any medication, there is always some risk, but the risk is minimal and the benefits are great. In order remove the hard plaque, sharp or other painful tools may be used. Because the tools must reach deep into the gum line, even the subtlest movement can cause damage to a pet’s mouth. This also allows the doctor to perform a thorough oral examination on your pet.
