“We have had our dogs on Advantage multi for over 4 years. They are healthy and have never gotten fleas. We have a lot of mosquitoes around here and although they don’t spend a huge amount of time outside, we’ve never had any heart worm or parasite issues. They never get sick from it either. I like that it’s topical. The only thing is, you can’t come in contact with it til it dries on them because it’s poisonous to humans. So be mindful of that around the little ones.”
