Physical exam, x-rays, electrocardiogram and an ultrasound of the heart will offer great information and will help your veterinarian and veterinary cardiologist make a diagnosis and create a treatment plan for your dog. Close monitoring may be needed after initiating therapy, as the medications prescribed can affect other internal organs.
When therapy is successful, you will notice a decrease in coughing and an improved ability to breath. As a rule of thumb, your veterinarian will ask you to report if the breathing rate is faster than 40 breaths per minute at rest.
Much progress has been made in the treatment of heart failure and with proper care and monitoring, your dog's quality and length of life can be greatly improved.
Heartworm disease mainly affects dogs but sometimes affects cats. It’s found in warmer and temperate climates and it caused by the bite of a mosquito. It affects dogs in all 48 continental states, and Hawaii, Puerto Rico, the US Virgin Islands, and Guam. It is not usually found in Alaska because the weather isn’t consistently warm enough for the worm to grow in the mosquito and cause disease in dogs. It is also found in wild animals such as wolves, coyotes, and foxes. In North America, heartworm disease is most easily spread in July and August.
Heartworm is caused by a worm called Dirofilaria immitis. It has a life cycle where the mosquito picks up the early worm stage called Larva 1 from the blood of an infected animal and then the worm goes through several stages in the mosquito and is spread to a new animal when the mosquito bites it. It then takes at least six months before the dog can be tested to show that it has heartworm. The worms can grow to be 10 inches long and there can be many worms. They live in the heart and lungs of dogs and cause severe damage. Testing is done annually to prevent this damage so treatment can be initiated quickly.
There are several products that can prevent heartworm. These medications should be given monthly year round. The medications also contain a preventative for intestinal worms, such as roundworms and hookworms. Giving the medication continuously is best even in northern climates that do not have mosquitoes year round. It also helps to get in a routine. Even forgetting one month of prevention can cause heartworm to develop.
Heartworm can be treated safely in most dogs, but it has some risk and is expensive. Once a dog tests positive, we will do additional testing to see if there has been some damage. Radiographs sometimes show damage to the heart and blood vessels. The heart can enlarge on the right side of the heart where the worms live. This x-ray picture is called a Reverse D because the heart looks like a backwards letter D.
Blood work is done to see if there is any organ damage. There is a strict protocol for treating heartworm in dogs that is recommended by the American Heartworm Society. On the first day of treatment the dog is started on heartworm prevention monthly. Prednisone, an anti-inflammatory, is started for several weeks to prevent lung damage. An antibiotic, doxycycline, is started to help with complication that can be caused by a bacteria that lives in the worm, called Wolbachia. The dog must be kep very quiet, no running at all while it is being treated. As the worms die they can block the blood vessels to the lungs and cause very serious lung disease and even death.
On day 60, the medication that kills the adult worms, called melarsomine is injected into the dog’s back muscle. Prednisone is started again to protect the lungs. The next month, two shots of melarsomine are given a day apart. Prednisone is started again. The dog must be kept very quiet for 2 months after this last injection to prevent thromboemboli of the dead worms from affecting the lungs. This is a very important part of the treatment as the dog can die from the dead worm breaking off in large pieces in the lungs. During the fourth month, the blood is tested for microfilariae (immature worms). If the immature worms are present, a medication is given. We must wait 6 months before testing for heartworm again to make sure the worms are gone.
Advocates of raw diets argue that raw diets are better for cats and dogs, but the purported benefits of raw diets are either not supported by research or are not due to the diet being raw per se (see "The Raw Truth, Part 1", located under Westgate Pet Clinic's "our veterinarian's page" under Dr. Karlin).
Since there are no demonstrated benefits and there are risks associated with feeding raw diets, the AVMA (American Veterinary Medical Association) and AAHA (American Animal Hospital Association) have both issued statements against feeding raw diets to cats and dogs. The main objections to feeding raw diets relate to concerns about bacterial contamination and concerns that raw diets may not be complete and balanced.
To make matters worse, it was determined that the outbreak was caused by a strain of canine influenza not previously seen in the United States. This new strain, H3N2, was thought to have originated in Asia.
For the past decade, the only known canine influenza virus type was strain H3N8. This strain of influenza has been traveling around the United States and causing outbreaks of infection for many years.
The new H3N2 strain of influenza did make its way to Minnesota and confirmed cases were found in dogs residing in Detroit Lakes and St. Paul.
Up until recently, the only canine influenza vaccine that was available was for the H3N8 strain. Westgate Pet Clinic was previously recommending vaccinating dogs for H3N8, with the hopes that it would provide some protection against the H3N2 strain.
Westgate Pet Clinic now has the H3N2 strain of influenza vaccine available. This vaccine needs to be boostered 3 weeks after the initial vaccine, and then yearly after that.
