i've spoke with my vet about the new heartworm medication. it's a shot that lasts for 6 months. She said that it was new and she was trying it with some other patients. i live in florida with alot of misquitos and am worried that it might wear off early or cause a severe reaction. are these valid concerns or is there more information i can get before giving this shot to my dog?
I have been using it for about a year and have not encountered any problems. vetcare
