We've used Heartgard for as long as we've had Carl. But with 3 dogs that started to get really expensive. Both our dog class instructor and my best friend just use this stuff called Ivermectin (sp?). It's cow worming medicine, but it's the same stuff that's in the Heartgard pills. Neither of them have ever had any problem with Heartworm - and they have lots of dogs. So, we started using this last week. You give this stuff to them monthly. My dog instructor said this is what they used before they had heartworm pills.

Going to training classes 4 nights a week we thought it would be well worth it to put them on Flea Prevention pills. We use Program, because this is what our vet recommended.
