Sentinel is one I am certainly considering as well. I just want to have a few good names of products to go talk to my vet about to switch to. right now he has my Shih Tzu on Trifexis. although we have never had problems with it, it is expensive and I decided Id rather just switch and be safe with all the stuff being said about it. My yorkie pup hasnt been started yet, but I know I dont want her on Trifexis.
