My dog smelled it walked away and hasn’t touched it!!!

Not to mention this special diet crsp isn’t cheap and you can not get a sampler to see if your fur baby will even it which is ridiculous in my book

Veterinarian suggested this even tho piggy has chicken allergy for her bladder stone. The way the chicken is freez dried in this formula, it does not effect her , she has no chicken allergy from this. She likes the taste and I believe it is helping her condition.

Cleared up lots of bladder stones

So grateful for this food. Our dog had a belly full of bladder stones shown in an xray in July and our vet put her on this food because she also has gi issues and used to need an rx food for that. We were thinking we'd need to have surgery because of the amount of stones, but we had her checked in mid October and they are gone. Cannot believe it and I'm so grateful this saved her from having surgery. She also loves the taste of it and gained 4 lbs from it... So we are watching her intake now. Vet said this was normal for urinary rx food.

Bears developed some kidney/liver issues that recommended switching to this food. He was already on a prescription diet so we were a little hesitant. He loves it

Bears developed some kidney/liver issues that recommended switching to this food. He was already on a prescription diet so we were a little hesitant. He loves it and has had no problems with the switch, so we are pleased. Hopefully, it helps his issues.

So Fast & Convenient

I’m so glad you’re carrying this food now! My dog was on a prescription diet previously and I got it through you. When she had to change to the multi function food

I’m so glad you’re carrying this food now! My dog was on a prescription diet previously and I got it through you. When she had to change to the multi function food I was disappointed that you didn’t carry it. Now that you are I know I can get it quickly and easily. It’s amazing how fast I get your deliveries. It’s just a matter of 2-3 days from “Review your Auto Ship” to having it at my door. I really appreciate that!

My dog ate it !

Although it was new at first and she eventually lost interest , just a little special broth I made to pour on it made all the difference.
