Heartworm

Heartworm has been diagnosed in dogs in all parts of the world and is actually very common. This may be due to the fact that heartworm has a virtual 100% prevalence rate in unprotected dogs living in highly endemic areas. Heartworm, also known as Dirofilaria immitis, is transmitted by mosquitoes. The mosquito injects a microscopic larvae which grows into an adult worm six to eighteen inches long inside the heart of the affected dog.

The worms can cause mild symptoms, such as coughing, but with time, more severe symptoms such as congestive heart failure, weight loss, fluid build up in the abdomen, fainting spells, anemia, collapse, and death usually occur.

Luckily we have several excellent medications which can prevent heartworm if given as directed. There are oral medications which need to be given monthly, and which also help protect against some intestinal parasites. There is one topical medication which is also applied monthly. An injectable medication, ProHeart, which is administered every six months, is back on the market after being withdrawn for several years.

Even if a dog has been given preventatives, it is still important to have annual checkups for heartworms by doing a blood test. Many people are not totally compliant about giving the preventive medication on time, and no medication works perfectly. If a dog has heartworms and it is given a dose of preventative, there can be a reaction that is detrimental to the dog, even deadly.

Heartworms were once thought to be rare in cats. Now we know the incidence is anywhere from 10% to 50% of the canine rate. Heartworm disease in cats is different than in dogs. Cats usually test negative on the routine blood test done in the hospital, the worms are smaller and usually do not produce microfilaria which are like baby heartworms that circulate in the bloodstream. Veterinarians have to do different tests, sometimes more than one, to diagnose heartworms in cats.

The symptoms in cats are different also. Cats usually have asthma signs or cough, even vomit. Cats can die acutely. The treatment for adult heartworms in dogs is expensive and potentially harmful to the dog. This is why it is much better to just prevent them in the first place. There is not a treatment for adult heartworms in cats. Many veterinarians are now recommending monthly heartworms preventative for cats in addition to dogs, since heartworm can be such a serious problem.

    Bart V.
  • "I will continue to bring my furkids to Buck Road. They are absolutely wonderful with my dog and have been a great resource for my cat who suffers from allergies and kidney problems. They really care about their patients and their humans, and listen to me when I have concerns. They are never, ever overcrowded. Usually there is maybe one other dog in the waiting room. That is a relief and keeps everyone's stress levels down! The facility is clean and staff is always friendly and willing to walk you through, step by step, the treatment plan ahead. I never leave feeling confused. I love this place - and we keep coming back despite moving pretty far away!"

  • "I've been bringing my pets to Buck Road Animal Hospital almost from the time they started and I have never had anything but positive experiences there. The staff feel like friends to me and they always make you feel like they're happy to see you and your pets. The vets take their time with you and your pets and they go out of their way to give you any information you might need about a pet's condition or treatment. I have A LOT of pets and some of my dogs have aggression issues but you'd never know it to see them there. They understand how to make any animal feel at ease and even my most difficult dog is welcomed there. I'd never go anywhere else. Best veterinary practice anywhere."
