Extremely great with ticks, very good with fleas.

Bear doesn't like the flavor so I always have to poke it down his throat every month, not something I relish doing. I think it's supposed to be braised liver or beef. With it was chicken or even bacon. He's such a tiny guy at 4lbs. Never see ticks, only see fleas if we go into an infested area as it kills them by biting poor Bear then dying.Unfortunately this means Bear requires a second medication to stop his scratching as he's allergic to flea bites. And he's had no internal parasites at all, just have to stay away from heavily flea infested areas.

We used to buy Simparica Trio monthly from the vet, but it was pricier and difficult to schedule time to go there to get it. I really appreciate the convenience of having multiple so it’s just one thing to schedule in my calendar to give it to her! Also, big Simparica Trio fan over here. We love going on long walks in nature, and unfortunately that means Deer Ticks. But even when we’ve haven’t seen them to pluck them off of her, the ticks just die and fall off (as long as we are consistent in giving medicine each month)!

I have used this medication ever since I brought my dogs home as puppies. We have never had any issues. One of them is 4 lbs and one is 7lbs. I love that it treats for fleas, ticks, heartworms, and other worms. I have never seen a flea or tick on my dogs nor worms. They have also never had a positive heartworm test either.
