Simparica TRIO

Lauren Stergis
I have purchased this item a few times over the last year for my dog and the product works great for her. No fleas/ticks and her last heartworm test was negative so I would say the product works. The best part is the great price from Sierra Pet Meds for it. While prices have gone up on virtually everything in this world, it is gratifying to find what you need at a great price, thanks Sierra!

My Doberman has never had a problem with this and having such a sensitive stomach that is something. It is so nice having 1 pill for flea, tick and heartworm and that’s effective
