My dog has been off heartworm medicine for about 3-6 months.
1) I wanted to know if it was okay for me to start him on heart worm preventative medicine now (interceptor) or should I take him to the vet to get tested and then start him on the drug?
2) Is there a problem if a dog has heart worm and you start him on intercept, and will it kill the heart worms if he does have it.
You should have your pet tested prior to starting the heatworm med. If your pet has heartworm disease then the interceptor will NOT treat it. vetcare
