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 An injectable medication, ProHeart, which is administered every six months, is back on the market after being withdrawn for several years.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.

Read What Our Clients Say

  • "We have a new 8 week Boston Terrier that we took to Springfield Vet yesterday for the first time. Absolutely pleased with the service, attitudes and genuine care shown to our little boy. The whole team was so professional, but took time to talk to you and explain everything. Dr Cynthia Wiseman is so wonderful, she sat in the floor did Logan's exam and played with him. What bedside manners. I will continue to use them, I highly recommend them to anyone looking for a caring and professional vet."

  • "We absolutely love this vet clinic and the staff! The facilities are modern and always clean. Everyone is always so friendly and genuinely care for you and your animal- they make you feel as if you are apart of their family.

    Our boy, Samson, is a Rottie (and quite the problem child). We are usually in the clinic almost every other month for something and they are always so helpful and show great care and love for our pup! We are very picky/protective puppy parents, so we were very grateful to have found both Dr. Cynthia and Dr. Heath shortly after getting Samson.

    We have definitely found our "home" in the vet world, and would highly recommend to anyone who is currently looking!"

  • "I have taken my dog here since he was a puppy. The staff are so friendly and caring, a very clean place and they always get us in quickly. When we come in no one passes us without greeting my dog and I and they're never in a rush to get us out of there."

  • "We decided to start taking our new kitty here this past fall and we love it! He was not on his best behavior (to say the least) for his first appointment, and the staff was so patient and was still able to safely run his bloodwork and give him his vaccinations. Every service has been reasonably priced, and they did everything they possibly could to make sure that our little guy was off to a healthy start after we adopted him. What I love is that they really seem to focus on the small details, too, like trimming our cat's nails after remembering that I had expressed interest in doing so at a previous appointment, or supplementing his flea treatment with something to safely speed up the process. We will definitely keep coming here as long as we live in Springfield!"

  • "I have been taking my dog to SVC since 2012 and when I adopted my cat in 2015. I have never had a bad experience. We have seen Drs. Heath & Cynthia Wiseman and I love them both. Always professional, always take their time when looking my pets over, asking questions, and answering mine."

  • "We’ve been taking our Moose there for a few years now. After swallowing a toy when he was a puppy, getting fixed, having surgery on his eyelids a couple times, and most recently having a breed specific illness; I can I say I would recommend everyone to go here. They’ve taken the best care of our boy time and time again and went above and beyond."
