|What Can I Do to Prevent Heartworm?|
Luckily, there are several excellent heartworm preventatives available. Before starting preventative treatment in the dog though, a veterinarian will do a blood test to check for adult heartworms. If a dog is given the preventative medicine but it already has the infection, there can be a reaction that may be severe, even possibly fatal. So it is mandatory that all dogs be checked for the disease before starting any preventative. Also, several organizations, including the American Heartworm Society, recommend that dogs be tested annually for heartworm, and remain on the preventative medicine year round.
There are many brands of oral monthly preventatives, two types of topical monthly preventatives, and an injectable medication which is given every six months. All these medications are by prescription only.
If you have concerns, make an appointment to speak to your veterinarian about testing, prevention or treatment. Your veterinarian is a local expert at preventing and treating heartworm.
Heartworm is a long, string-like parasitic worm that has the scientific name Dirofilaria immitis. It earns its common name by living in the host’s heart, lungs, and blood vessels. Heartworm can cause severe lung disease, heart failure, organ damage, and death. It is transmitted only through mosquitoes to a variety of species including dogs, cats, ferrets, wolves, foxes, ferrets, sea lions, and in rare instances, humans. Heartworm can affect any breed of dog or cat.
Heartworm infects animals all over the world. Once inside an animal, a heartworm can live five to seven years, and grow up to twelve inches long. Adult heartworms look like strands of cooked spaghetti.
Mosquitoes spread heartworm to the host animal. When a mosquito bites the animal, it transmits infected larvae through the bite wound. Once inside an animal, it takes six or seven months for the larvae to mature into adult heartworms. These adult heartworms mate and the females release the offspring, called microfilariae, into the host animal’s bloodstream. Mosquitoes then ingest these microfilariae when they bite the infected animal, completing the lifecycle of heartworm.
The parasite lives inside a mosquito, and develops into infective larvae in 10 to 14 days. Microfilariae cannot become infective larvae without first passing through a mosquito. This means heartworm is spread only through mosquito bites and not by casual contact.
The presence of the parasites inside the heart and lungs causes a large degree of inflammation, and can severely interfere with blood flow. This can cause coughing, asthma -like signs, heart failure, weight loss, fluid build-up in the abdomen, or sudden death. If your pet develops heartworm, your veterinarian will do tests including chest x-rays and blood tests to determine how seriously it is affected. Treatment includes doxycycline and an injectable drug named Immiticde ℞ which is derived from arsenic. The treatment takes several months, and can also cause side effects.
For all these reasons, it is much better to just prevent heartworm in the first place.

We have been clients of Los Robles Animal Hospital since 1986 and have always received excellent service and pet care.
Best vet clinic in town!!
We love Los Robles!
There are no words to truly express how wonderful Los Robles is. The staff there has taken such good care of our dog over the years, and there is no one I trust more when it comes to her health and well being. Without their genuine care for her, she would not be the relatively healthy dog she is today. It is this attention to detail and genuine care for our pets well being that makes them like family to us. We are forever grateful for the people at Los Robles and all the things they have done for us and continue to do.
LRAH always exceeds my expectations. I LOVE this place - you have a customer for life
