The American Heartworm Society has good information on this debilitating and often fatal disease in dogs. Our discussion here will focus on the dog's disease prevention, and treatment. Cats can get heartworm, but do not suffer fatalities like the dogs. We will provide prevention and treatment to dogs until research deems it necessary and prudent to do so for cats in our area. The protocols used here are tailored to the individual dog's disease state, lifestyle and personality. This is not a one size fits all program. Prevention is offered after appropriate testing and monitoring and can be in the form of monthly pills, liquid, or a twice a year injection. Treatment can be a short, fairly inexpensive process, or it can be a long, step by step expensive series of medications. It is always best to prevent this disease in the first place. There is no state that is immune to this disease nor is there a time of year when it is safe to not be on prevention medication. Wild canids like the coyote also carry the disease and serve as a permanent reservoir of infection for our dogs. Jump to our Heartworm Page for more information.
