Safe for your pet

I'm pretty funny when it comes to me giving my dog pills for everything but I have large dogs which comes large problems. I stumbled upon this at the Humane Society Vet in my town and have stuck with it for years now. My dogs can take this on an empty stomach wrapped in something pill pockets ect. I keep the animal in for the next 3 hours so they don't try and eat grass and then get sick. They ingest the pills and in the next few hours you can see the fleas dying.My dogs got fleas from the squirrels in my yard and were misereable a few hours after this they are all so happy to not have fleas. Has a flowery smell to it so my dogs can smell when its coming so mask it.

Awesome product, amazing service!

Awesome product, I wouldn't even think about using anything else. I have used Comfortis for years with multiple dogs (my own and fosters) and it has never let me down... fleas gone within hours! This was the first time that I ordered medication from Chewy, and I have to say that I was pleasantly surprised with the ease and quickness of the entire process! Thank you Chewy!

KILLS FLEAS FAST

Our 2 labs Zoomer and Zeke had been scratching for weeks but we couldn't find any fleas on them. We ordered from Chewy and thought it would take a week or so to receive. We got it in 3 days from the day we ordered. Not to mention great price. This stuff works fast. Within 2 hours we saw fleas falling off them dying. Thank you Chewy!

Wonderful product

When we moved in with my mother in law to help take care of her. We had a Coocker Spaniel he did not have fleas till then and I heard Abigail this product I tried everything else first and nothing worked I gave him that and by the next day I didn't see any more fleas on him. And when my mother in law passed away she asked us if we would take care or her Australian Shepherd and he had hair missing because of fleas so we started giving him this and his hair came back and he no longer is digging at his skin.

Effective & Easy to use

It’s bitter but better than alternatives. Comfortis is super easy to crush w/ mortar & pestle, then sprinkle & mix into wet food. The only way I’ve found to ensure complete consumption.

Oops I messed up

I got this hoping it did all 3(flea,tick,Heartworm) my mistake. And my pup is 132 lbs so I didn’t get enough meds. This works great for my sister-but I need to pay more attention

Flea meds.

I was able to purchase my dog’s flea medication for the first time through Chewy. I was able to get a discount, for which I was very grateful. I received a call from Chewy, letting me know they were still working on contacting my dog’s vet. I really did appreciate them calling to let me know. The vet doesn’t even do that for their patients! I will keep ordering from Chewy from now on.
