Dog won’t eat it

I have a small mixed breed dog with separation anxiety that drugs don’t touch. I can’t really tell if this diet helps because he refuses to eat it. He sniffs it, looks at me, then walks away. I mixed with with another food and he’ll take a few mouthfuls but tries to eat around this food. He hasn’t eaten a full bowl of food in a month since starting this food. If you have a picky eater, beware, this food is too expensive for how unpalatable it is.

I have a young male pomsky with extreme anxiety (on Prozac) and this is the ONLY food that has made his poo solid! It is prescription food and a little pricey, but worth it to us. My only complaint is the size of the bag! 8 pound bag is as big as it comes!! I haven't been able to find it in a larger bag...please let me know if comes in a 20/30/40 pound bag. Thank you:)

My Vet suggested this food as a supplement to her regular food in order to keep her mood stablized. The food works great she seem more "calm".

Quite dog

Thank you Royal Canin for this amazing product. This has changed my dog after only two bags. He is calmer and doesn't bark at everything. He has a lot less anxiety now. Even people who come to visit us have commented on how much more relaxed he seems. I highly recommend this food to anyone with a spaz dog!

Miracle Food

This food literally brought peace back into our house hold. Im a veterinary technician that has tried everything for my Chihuahuas behavior issues. It has been a daily struggle for 9 years, we were 1 step away from putting her on Prozac. After starting the Calm diet Mias personality has changed for the better. She's playing again, not urinating or defecating in the house or biting at people, and wants to be part of the family again. And she just seems generally happier which is the best part. Thank you so much for providing such a wonderful product!

We love hearing that Mia is doing better!

Kibble is perfect size

I have a hyperactive 3 year old miniature poodle who finds it difficult to settle down. My vet gave her an injection to calm the licking, itching and overall behavior. He also suggested I try Royal Canin Calm. I’m sure the injection has long worn off as this was several months ago and I see improved behavior.

My dog loves it!

I'm so happy to give food to my dog that is good for her and something she enjoys.

Satisfied with product

I had been feeding my dog Urinary SO but was recommended this product due to her nervous nature and it being part of the s/o index. She is a complicated case but I think the food does help and best thing is she loves it!

Great quality diet

My dachshund loves this food, and I love knowing that he's getting great quality ingredients with the research to back it up. I do wish there was a moderate calorie option do that he didn't have to eat such a tiny amount.
