Never tried it, but it sounds bad since I read it could be purchased at petsmart according to a site (did a quick google search). I bought a flea medicine at petsmart and later found out it was almost deadly. Well not really but has a TON of side effects.
"I have never heard of Vectra before, but a quick google search indicates that the veterinarians are getting some generous kickbacks for pushing this product. Just a heads up." -

At the place I volunteer for the doctor mentioned that many people have been saying how advantage and frontline aren't working as well as they used to and they have to use it more often. He suggested Comfortis. I'm switching over as soon as we run out of advantage.. in 6 months lol.
"I actually couldn't find much info about using it for a spot treatment except in a patent application for Hartz (which is owned by the same parent company that owns the maker of Vectra)"
(same website as before, Hartz is terrible. Will never buy anything from them.)
