They will need to be tested for heartworms before you can give them any heartworm preventative, which you need a prescription for. Your vet will have to give it to you. I use Heartgard Plus, and it's a chewable, so there should be no problem getting them to take it. My guys stay on it year round, not just in the warm months. Even a warm spell in the middle of winter will bring out the mosquitoes, so it's better to be safe than sorry.![]()
