“Originally I purchased Sentinel through Allivet and not the vet office because of the price difference. Through my vet I was paying $52 every three months (I have 2 small dogs who take this monthly for fleas/heart worm protection), through Allivet I pay about the same price for a six month supply...recently my vet office stopped carrying this product so now more than ever I'm thankful for Allivet!”
