My whippet has been on revolution with good results for flea control. He has not been on additional heartworm meds. Considering changing to Advantix, which repels mosquitos. Should he also receive heartworm meds? If so, which?
Yes, your pet will need heartworm meds if you change to advantix b/c advantix does not prevent heartworm. Some options are Hartguard Plus and Interceptor. vetcare
