I used Revolution at the advice of my vet. Deegan was nine weeks old at the time and weighed 2.5lbs. It says that it is ok, for puppies 8 wks and older, but always consult with your vet.
I really like Revolution because it covers a number of things, such as, worms, mange, fleas and tick and larva and a couple other things too, but I can't remember exactly.
I had a bad experience with Frontline one time with my Sheltie and will never use it again.
As for the butt thing, I am not sure totally. Could just be itchy, could worms, but I would watch him and if he conitues to do it, ask the vet. |
