Q. Does a 2 yr old dog have to be tested two times a year for heart worms when the first test was good

Answered By
PAULA SIMONS

A. The heart worm test does need to be repeated if your dog was not on heart worm medication consistently every month through out the year. If your dog had it's heart worm medication every month without fail, it may not be important to do bi-annual heart worm screenings unless you are concerned about Lyme disease. (The heart worm test will also test for Lyme and a few other tick borne diseases)
