Thank you Dr. Lee. I am not sure if Whipworms are a problem here in Phoenix. I like the idea of Heartgard giving a guarantee on their product as well as all of their donations to animals.

My question now is, if my vet only wrote a 6 month prescription, do i need to go to the vet every 6 months to get a refill prescription and a heartworm test? If I have a year supply for my other dog, do I need to get him retested after 1 year or will vets generally refill the rx without another heartworm test?

Thank you.
