What is the difference between Revolution and Stronghold medications?
I just started Revolution (bought from a vet) for a small dog, but would like to try it on my larger dog, too. I want to buy it online.

I believe Stronghold is not a product sold in the USA. Both are selamectin. A prescription will be required in the United States to purchase selamectin as it's a heartworm product, and the dog needs to be tested by a vet before using it since if it's given to a heartworm positive dog, it can kill.
