“I've been using it for over a year for two small dogs 12 - 16 LBS each and they have no negative reactions. No problem with any parasites or fleas. Good product.”
“Sentinel spectrum is just what we needed to control fleas! Living in Fl is hard not to have fleas. Even humans bring them on the house. Allivet is a Fl based company highly suggested by my Vet. for low cost and convience. I use them for all my animals.”
