About Dog Heartworm Testing
 

Heartworm disease is a dangerous, but completely preventable infection where parasitic worms grow inside the chambers of your dog or cat's heart and large blood vessels. Left undetected, heartworm disease can become serious and even result in death as worms eventually block blood flow to the heart and lungs. That's why heartworm prevention and early detection are so important! Protect your dog & cat against the dangers of heartworm. By offering both brand name dog heartworm medicines like Heartgard Plus, Interceptor, Sentinel, and Revolution - PLUS economical, FDA-approved bio-equivalents like Tri-Heart Plus - we believe more dogs & cats will be able to receive the heartworm protection they need.

New products on the market include Advantage Multi, a topical heartworm preventive, which also protects against fleas and certain intestinal worms in dogs and cats, and Iverhart Max, a heartworm preventive that protects from most intestinal worms, including tapeworm!

Heartworm Disease, caused by the parasite Dirofilaria immitis, was once considered a disease of the southern United States. But it is now found in every state in the continental United States. The mosquito is the only known vector for transmitting heartworm. Microfilariae enter a mosquito when it bites an infected pet. In 10-28 days they mature into larvae. The larvae enter a new animal's body when it is bitten by an infected mosquito. Larvae mature and migrate to the pet's heart. Worms in the heart mate and produce microfilariae (6-7 months after infection in dogs, 8 months in cats).

An important part of a complete heartworm prevention program is testing. All dogs should be tested for heartworm infection before starting a preventive program. Testing ensures that your pet is free of adult heartworms, and ready to start or continue on heartworm preventive medication. The American Heartworm Society (AHS) estimates that only 50% of dogs in areas where heartworm occurs are actually on heartworm preventives. Of those prescribed heartworm prevention products, only about 75% receive all of the doses. Since heartworm continues to be a fatal disease and pet owners' compliance with heartworm prevention is less than optimal, the AHS recommends these guidelines for heartworm testing >

* In a small percentage of ivermectin/pyrantel treated dogs, digestive and neurological side effects may occur.
