Heartworm Preventatives for Cats
Currently there are two forms of heartworm preventative approved for use in the cat.
Heartworm Preventatives for Dogs
Currently all heartworm products for dogs are given on a monthly basis. These should only be given to dogs who have been tested for heartworms and found to be free of disease. The cost of testing is nominal and only requires taking a blood sample. Most veterinary clinics will conduct the test in a hospital laboratory and have the results 8 to 10 minutes later.
