Excellent service, great pricing

When we took a look at what our vet was charging (for like 5 pills!) we knew we needed different solution. Chewy is a fantastic resource for us, our girl is older

When we took a look at what our vet was charging (for like 5 pills!) we knew we needed different solution. Chewy is a fantastic resource for us, our girl is older and on multiple meds. Their RX pricing keeps things from spiraling financially.

Probably the people who answer the phone when I call

Without this meds my Willy won't eat.We always had a problem with him not eating.I think bc he ended up being abused and not given any food.

My cat Franklin needs this to counteract the effects from another necessary medication. It works very well. 2mg is the same dosage contained in a dose of the transdermal gel, and much cheaper.

Unfortunately, I lost my boy, Star, before I had a chance to use these, so I passed them on to a friend whose pet needed them. But the price was so much better than any place else I checked. I should have known Chewy would be the best! They always are!

Yeah....she's eating again!!!

I have a 13 yr-old dog who was struggling to eat due to anxiety. She was regularly losing weight every month she was weighed. At first, I thought it was the food

I have a 13 yr-old dog who was struggling to eat due to anxiety. She was regularly losing weight every month she was weighed. At first, I thought it was the food. I changed that out. It worked for a couple of weeks but she started to not want to eat if I was away, etc. She will start to eat within 10 min of giving her this pill. She has also eaten despite my being out of the house. She's finally back to a healthy weight.
