But annual testing of dogs that are on heartworm preventative is not necessary. While testing that often is not harmful to the dog, it can take a toll on your wallet. Unless you feel the need to test that often, you should just keep your dog on the preventative. 4 мая 2021 г.
Does my dog need heartworm test?
Annual testing is necessary, even when dogs are on heartworm prevention year-round, to ensure that the prevention program is working. Heartworm medications are highly effective, but dogs can still become infected. If you miss just one dose of a monthly medication—or give it late—it can leave your dog unprotected.
Is heartworm blood test necessary?
In a word, yes. Heartworm testing is very important to the health of your dog. If your dog is heartworm positive and you put it on certain types of heartworm preventative, it could have detrimental effects, including death.
When should a heartworm test be done?
Any dog of any age can, and should, be tested annually. Since it takes 6 months for a pet to develop a positive response on a heartworm test, we recommend that annual testing begin no earlier than 6 months after the end of the heartworm season of the previous year which is usually considered to be October 15th.
