Can a 4 month old collie use interceptor and advocate for heartworm prevention?
Vet gave pet Interceptor Yellow at last visit, and one tablet to take in a month. Since then have bought Advocate which also claims to prevent heartworms. It is time for the Interceptor, but applied the Advocate last week. Worried about the two together causiing her problems.
