Highly recommended by vet

My vet asked what food I give my dogs and when I said Royal Canin he replied, “Oh, that’s the best!” Made me feel reassured that they were getting the quality of food I was hoping for. We switched from adult to the senior version of this food and both dogs love it just as much.

Good Choice

My dogs have always eaten Royal Canin but my current boxer decided she no longer was interested unless "goodies" were added. I switched from 7+ years to the 10+ and she's happy and eating with or without the added enticements,

What my vet recommends

As always, Chewy made it so easy to get the diet my vet recommends for my senior pup. Ingredients are very consistent so she never has any gastrointestinal issues.

Well liked

I have been using Royal Canin products off and on since 2004 with my cats. My daughter’s Aussie has been staying with me for the past year. I put him on the senior formula for medium dogs. He seems to like and tolerate it well. (He’s not at all spoiled. He gets RC for 3 weeks of month and gets a “casserole “ of boiled or roasted chicken, pumpkin, rice, peas, green beans, apples or cranberries and spinach for the 4th week. ) He just turned 14. I am pleased with the Royal Canin product line.

senior dog loves it - finally eats again!

We fed Taste of the Wild for 10 years. When our dog got older, he started being less interested in the old food. He also started having loose stools and generally seemed like he had belly aches. We switched to this brand after our vet recommended and we did a lot of research. We transitioned food very slowly, as he had been on grain free all his life. He loved it and would pick out the new food from his bowl. He now eats the Royal Canin only and gobbles it up! His stools are much firmer now and he whines less (probably because he actually eats and isn’t hungry all the time!).

Out of 7+ years, so bought 10+

My dog is 8.5 years old, and I use the Royal Canin 7+ food for medium sized dogs. This time, the 7+ food was out of stock, so I tried the 10+ food. The dog likes the food, and I appreciated having SOMETHING to order, as all the local stores didn't have anything similar to my needs. Chewy came through!

So impressed with chewy

Chewy always has what I need at a fair price and expedited shipment for no extra cost! I can hardly purchase this 10+ food anywhere anymore. They have either ran out or the price is too high! But it’s always available at Chewy

Good product

My older lab really seemed to like this food, however, when I went to reorder, it was out-of-stock :(

She is finally eating again

Our 16 year old baby is finally eating again. She has become very picky in her old age and the boxer food she once loved is just too much for her. We were having to soak the large pieces in water and hope that she would eat the mush. Day one with this senior food and she inhaled it!!! So far no bloating or gas, which is amazing! (We did mix it with the previous food, but she basically sifted out the new bites)

Saved our 13 yr old sheltie

If you have a senior dog that has trouble getting around, this is the food! About a year ago, our blind sheltie started having trouble getting up and would drag his back legs. It was so bad, we had to start carrying him around everywhere. He would whine and panic every time he tried to get up and couldn't. I randomly bought this food since its one of the few marketed for 10+ years. Ever since he started eating this in feb, he no longer has trouble moving around or getting up. It took about a month of eating this food to see the results, but we are so happy with this purchase!
