A breeder told me this is the best dog food, didn't even want to go there with all the grain free fluff out there. I started two pups on RC. Puppy formula was good but they been on adult medium for quite some time now and they're not so hot for it in the past 6 months or so. It is Dec 4, 25 right now.. One also dev itchy skin, now I see you changed formula? Why do you do this? Leave well enough alone. My Persian cat food is the same way. She used to look forward to eating her kibble. Not so much anymore. I'm getting worried. Also the closure on the big bag of Medium dog always falls off. You need to fix that. Also reconsider going back to the previous formula. I need to have a word with the breeder I know. He says he knows people at RC. I need to find out if I should switch.

So far I absolutely LOVE this food! My dogs are extremely picky and they eat their kibble with no issues now. It’s stinky but not super oily. Their blood labs came back great. They both have more energy and we haven’t had any infection issues with my older dog. She doesn’t get nearly as yeasty anymore. 10/10 recommend this food, especially with all the research that backs it!

I can’t say enough good things about this food. We have a pitsky who was struggling with digestive troubles. We switched him to this brand and he has now been eating this food for 6 months. I’ve noticed that he has significantly more energy, his stool quality is excellent, his labs are perfect, his coat is shiny and glossy, and he gobbles his food down with excitement with each meal. I am so impressed with this brand.

When my wife opened the box the dog food spilled out everywhere. The bag had a big hole in the side and we ended up losing a lot of what we paid for plus had to find an alternative for storing what we could save since the reclosable bag was destroyed. My doga love the food but I am very disappointed with the packaging.

We have feed Charlie this Royal Canin food for 4 years and suddenly, a month ago, he started to have a skin allergy. We couldn’t figure out what it was and then finally, Royal Canin had changed their formulation. This change introduced more grain into Charlie’s diet and he immediately had an allergic reaction. He was scratching so aggressively that he had lost out in places and wasn’t able to relax. He would be asleep and jump right up to scratch. Once we changed his food to a raw diet, for now, he improved overnight. Back to his energetic self and happy Be aware of changes in the foods for your pets. The bag takes longer to reflect the change than their websites.
