The girl gets Interceptor or Sentinel for heartworms. If she is taking
interceptor and gets fleas then I use Frontline Plus. If she were to be taking Sentinel at the time I'd probably go with Advantage.
Thr boy takes Heartgard Plus. Thinking about changing him to Interceptor. No good reason why though. I just feel like it.
I've used Frontline Plus on him. Thinking about going to Sentinel for the summer.
I don't like Revolution and am watching Advantage Multi to see how other dogs react. Too new for me. I tend to accidentally bathe after topicals anyway. Pills are better here.
For heartworm drug usage, we follow the recommendations of the AHS.
