DO NOT ORDER THIS PRODUCT FROM PETCO. I submitted my order on a Wednesday evening and sent my prescription. Re-uploaded it twice. Called 3 times, messaged online support 3 times. Received no help or guidance. Then 5 days later was told to mail in my prescription. 2 days after I mailed it they said my order had been cancelled. If your pet has a prescription and its life depends on it then it might die. Not worth the risk. Absolutely abominable customer service.

My Greater Swiss Mountain Dog has been on Ultamino for the last 3 years. Up until lately, the product has generally been fine, though the clumping that others mentioned have been in quite a few bags. The last 2 bags however, have an oily residue on the kibble, to the point that you can't put it in your pocket for walks without it staining your clothes. You also cannot place it on the carpet for the same reason. Has the formulation changed? If so, it may be time to explore a new product.

After dealing with soft stools, vomiting, and eventually some very quick weight loss, our vet diagnosed our 3 year old Rottweiler with IBD and recommended this food. For the first time in our rotties life, she finally started having firm stools and gained all the weight back. She also seems much happier.

“Quality Manufacturing” No way!! Come on, Royal Canin…get you act together on the production of this food. For the fifth time since 2021 and the second time in a month, I received a bag of this with huge solid clumps of food…some as large as paver bricks. I have to give this food to my dog because of food allergies and it has been a godsend, but now she has been sick the last two weeks and it makes me wonder if these poorly controlled bags are to blame. Given the amount of money this food costs and what’s at stake (the health of my dog!) we expect better!!

If I could give it 0 stars I would. This food made my complete healthy dog develop pancreatitis. My vet prescribed me this food to see if my dog had a food allergy because of skin/itchiness. The first day of feeding my dog this food he was excessively drinking water every 5 minutes which was very alarming to me. As weeks go by he’s starts excessively stretching. Comes to find out he has pancreatitis when he was completely healthy before starting this food. DONT feed your dog this food this is a WARNING. I will be posting about this food all over platforms to warn every single pet owner!

My dog has allergies and the food was recommended by my vet; My dog likes it but when the bag was received it was virtually a solid block. I thought perhaps it froze in route. Nope. There were a few smaller clumps that I was able to break apart but I have 2 solid blocks, the size of a block of ice and cannot chip away at it - Prior bags were fine - this is the first time I have had this problem I have been told by Royal canin: 12/28/2024 Thank you for reaching out to Royal Canin and for sharing your concerns, I am so sorry to hear about this issue. Of course that this is not the quality that we wish for you and your fur baby Gretel to receive. Ultamino is a very “temperamental” product to produce, as the feather hydrolysate is an extremely fine powder that gums up the extruder very quickly. This can lead to variation in kibble size and a stickier kibble consistency, which can lead to kibble clumping. If the moisture level of the kibbles is too low, the kibble won't form properly and palatability goes down, if the moisture level is too high, the kibbles clump together more easily. The plant has been working on ways to minimize this, however it continues to be a challenging product to produce.  Unfortunately, since you do not have the original bag anymore we cannot replace the product nor register your complaint in our system. We do understand your concerns, but without the batch details which are found in the bag, we have no way to investigate or report your complaint.

My dog has seasonal and food allergies. He was on acana for nearly 5 years until it was bought by Purina and the ingredients changed, causing him significant food allergies. We tried other over the counter foods but he still had itching and bloody stools. Switched to this and he's back to normal. My dog gets endless compliments on his coat and his seasonal allergies have improved since using the prescription food. It smells decent for dog food too. I know purina owns royal canin, but somehow it works.

My dogs have bad allergies and have been on this -successfully - for a few years. The bag I received two months ago had some clumping of the kibble, very hard to break apart. Just received another bag from chewy.com and half of the kibble at the bottom is glued together and won’t break apart. There is a separate bread loaf sized brick that I’ve had some luck breaking apart, but with over half the bag’s kibble blued together and not breaking off, most of the bag is unusable. Not a cheap product, this seems like a major control issue. Very few options for hydrolized protein diet, am going to talk to my vet about other options…
