My Stella loves it

We began noticing are big girl Stella having some stiffness when getting up so my vet referred me to Royal Canin. After a month on this diet we have noticed a vast improvement in her. She no longer has difficulty getting up and in the morning in the morning and in fact has started acting like a puppy again! Thank you for improving my Stella's health and mobility!

Best Choice

This was recommended by our vet because my dog was having reactions to other food and having would stop eating, after we made the switch she eats as soon as I put it down every time with no issues, and showing health improvements, it’s expensive but it’s worth it for my healthy best friend

Helped Our Lab's Injured Knee

Our lab injured her knee and we were told she may need surgery if a treatment plan of meds and glucosamine supplements failed. She wasn't getting well enough to take off the meds until our vet placed her on this diet. Within weeks, we were able to cut back on her meds and surgery is no longer on the table. We couldn't be happier.

Monies worth

I used earlier other dog food ; my tassy used to eat but after a mouthful or two she walks away. Ever since we started with Royal Canin,we literally have to pull her away from it.

Love the omegas

All of my dogs are fed this and they love it. Jumping around at dinner time...can’t wait. The omegas are great for their coat. They are labs and are basically waterproof!

One of the best foods out there!

Our almost 13 year old American Bulldog absolutely loves this food. Not only does her coat look better but this has been amazing with her mobility. We had tried Adequan glucosamine injections at the vet with not much luck but after weeks on this we can already tell a difference! Thank you for all your innovative products!
Royal Canin response

Terrific taste!

My Labrador loves this food. I know she is a Lab but she eats with gusto. Thank you. And, although she is 11+ she is still very active and runs around, in and out of the lakes. Always tons of energy.

Great food!

My 9-year-old weimaraner has been eating this for 2 years. I don't have a dramatic story; I put her on this when she reached "senior status" in the hopes of protecting her joints as she ages. She looks amazing. Her haircoat is soft and shiny, she maintains a good weight, and her stools are small and perfect. She loves the food and I love Royal Canin!
