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.

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.

My vet does not carry Simparica Trio for small pets. It’s very easy to order from Chewy. My vet provided the written prescription, I just had to order it online and then mail in the prescription. The prescription is good for a year.

Peace of mind

Got this for our pug puppy as her first ever dose, and she had no issues or reactions. It was also very easy to give to her, as she ate it just like a normal treat

Too complicated

I understand that for fleas medicine the laws ask for vet approval.. but is it difficult to look for the vet approval “EVERY SINGLE TIME ”you need the medicine.

Easy and convenient

Chewy reached out directly to the Vet to obtain the prescription, within 4 days we had already received the medication. The pill is easy for a small dog to swal

Way Too Expensive

Price was almost double from the first time I ordered it. It was expensive the first time, so it's too expensive for me.
