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.

We have tried many flea products trying to get rid of a bad flea infestation after we fostered puppies. This is the only thing that worked. It took a few weeks to actually get these with the prescription process, but all the dogs are are not itching anymore. Fleas are gone after one treatment so far.

I've had dogs for 20+ years and Comfortis has been the ONLY medication that works fast and well! I have never had an issue with my dogs taking it either. Highly recommend!

We use this product with a prescription and send it through Chewy for the price. It works for our puppy and is better than a lot of other brands and you only have to give it with food once a month.

Absolutely works great! Having it shipped is the best thing ever!

I have three dogs. If I treat all three at the same time with Comfortis, it rids not only my dogs of fleas, but my house as well. I'm not sure how that works, but it does. While described as a monthly treatment, I find that unnecessary. I just wait until I see fleas again. I had to treat them this week; but before that, my last treatment was so long ago that I don't remember it. It's been literally years.

My monster dog has allergies. Even after adjusting food, shampoos, you name it, she was pulling her hair out and scratching endlessly. Comfortis is the only medication that has stopped the itching. Her coat is shiny, bright and she has quit pulling at herself, rolling constantly. It's a relief to me that she feels relief.

This product works so well and I couldn't get it in my area. Chewy .com is a pet saver! Thanks so much!

Fleas are an issue this year, never prior. I tried every natural product which would more than likely work if it wasn't a horrendously bad year of flea explosion. I'm extremely hesitant to use anything chemical but had to give in and after researching decided Comfortis would do the least harm to the dogs. Ticks have not been a problem so I couldn't see also adding that chemical into their bodies.

I needed to get a new prescription of Comfortis for my dog, which had to be approved by her vet. Chewy helped with this and within a few days the Comfortis arrived on my doorstep. So easy!!
