Guest Blog: Feline Heartworm Disease





By: Scott Gellman, VMD
1. My Indoor Cat Can’t Get Heartworms.
Heartworm disease has been found in all 50 states, in all climates, and in mosquitoes both inside and outside homes. All cat owners should be mindful of the fact that it only takes one mosquito to infect a cat, and the only way to reduce the risk of your cat becoming infected is to keep them on monthly heartworm preventive medication.
2. Heartworm Disease Is a Dog’s Disease.
The good news is cats do not suffer from heartworms as often as dogs do; however the disease they cause is equally serious. Unlike dogs, cats do not serve as a natural host. In fact, many worms in cats are produced in a smaller number and often die before reaching adulthood. A typical heartworm infection involves up to six worms, primarily juveniles. Despite smaller numbers, cats are still susceptible to serious pulmonary and cardiac damage while fighting, the often undiagnosed infection.
3. It’s a Heart Disease.
The name “heartworm disease” is a misnomer, as the disease mostly affects the lungs and not just the heart. Signs are often mistaken for feline asthma, allergic bronchitis or other respiratory diseases.
So what are the signs of heartworm disease in cats? The most common signs of feline heartworm disease are coughing, lethargy, and difficulty breathing. Periodic vomiting or anorexia may also be indicators of heartworm disease; and in more serious cases, weakness, collapse, seizures, or even sudden death.
4. Only Adult Heartworms Cause Problems.
Cats do not need an adult heartworm to start showing signs; in fact, larvae are a main cause of the problems. Studies show 50 percent of cats infected with heartworm larvae have significant disease of the small arteries supplying blood to the lungs. Since most worms in cats die before reaching adulthood, many infections are often missed. However, for those adult heartworms that do not die, they can live as long as 2-3 years in a cat, causing irreversible damage to the heart.
5. If My Cat Has Heartworms, I’ll know immediately.
Signs of heartworm disease can be difficult to detect in dogs or cats, especially in the early stages. In cats, signs of heartworm disease can be subtle and misleading because they’re similar to signs of many other feline diseases.
Application of a monthly preventative, such as Revolution, year-round is extremely important in preventing your cat falling prey to this devastating disease. It is equally important to stay up-to-date, as missing even a couple of months of preventative may give the worms the chance to reach adulthood.

Canine Flu In Chicago: How Does This Effect Your Dog?


In the past couple of days, several news outlets, including ABC News, TIME magazine, and CNN, have reported a rise in the number of canine influenza cases in the Chicago area. In the wake of this "outbreak" in Chicago, our doctors want to make sure you are well-informed about your pet’s health! 

Here are some fast facts about canine influenza and what you can do to protect your dogs.

What is Canine Influenza?
Canine influenza, or "dog flu," is a highly contagious respiratory disease in dogs caused by an influenza A H3N8 virus (not a human influenza virus) that originated as an equine (horse) influenza virus.

How is the virus spread?

  • An infected dog can pass it to another dog through aerosolized respiratory secretions (panting, sneezing, etc.)
  • Canine contact with contaminated objects 
  • By humans who move between infected and uninfected dogs

What are the symptoms?
  • Coughing
  • Sneezing
  • Fever
  • Clear nasal discharge that progress to thick, yellowish-green mucus
  • Rapid/difficult breathing
  • Loss of appetite
  • Lethargy

Should I be concerned with putting my dog in daycare or boarding at a kennel?
Dog owners should be aware that any situation that brings dogs together increases the risk of spread of communicable illnesses. As long as good infection control practices are in place, pet owners should not be overly concerned about putting dogs in training facilities, dog parks, kennels, or other areas frequented by dogs.1

How can I protect my dog from Canine Influenza?
Since dogs have no natural immunity to this virus, the canine influenza vaccination may be recommended (and often required by doggie daycares and kennels) for any dog who interacts with large numbers of dogs.

What should I do if I think my dog has Canine Influenza?
Schedule an appointment with your veterinarian so that he or she can examine and evaluate your dog and recommend an appropriate course of treatment.
