I worked at a vet clinic only until very recently. The vet I worked for is a younger vet and would not carry ProMeris or Comfortis. He said there had been many dogs have reactions and even died from these products. He does carry Revolution. Revolution works for smaller inside dogs. Although there have been some dogs it just doesn't work on. He also carried Frontline Plus. I use Frontline Plus on my dogs and I've had no problem with fleas at all.

As for heartworm prevention, I've only ever used Interceptor and that's all I'll ever use. It's very hard for the dog to overdose on it. We had a woman's Maltese open and eat an entire 6 month supply. It never fazed the dog. As said before Revolution also prevents heartworms. ALTHOUGH we've had a couple dogs come in that had been kept on Revolution get heartworms anyway.
