Easy to chew

[This review was collected as part of a promotion.] Been using Royal Canin dog food since our German Shepherd Angel was 6 mos old we had to put her on adult dog food because of birth defects. She just loved the adult food but when it started to get hard to chew we switched her over to the aging dog food. The adult food was a star shaped about an inch in diameter but the aging food was a oval shaped O that was easier to chew. She ate this food up until we had to put her to sleep at 13 1/2 yrs old. All Royal Canin food stayed with her not like the other food where she would have to go the bathroom 2 to 3 times a day this food she had her regular bathroom goings once a day. And our dog was very picky on what she ate this passed her pickyness because when we would take her to the vet the vet would give her treats she would not eat them at all. Thank you Royal Canin for being here in the time of need.

Great dog food

[This review was collected as part of a promotion.] Both dogs love the taste but don’t over eat b/c they get full quickly and are able to maintain weight. Love that it has the nutrients to keep them healthy as they are getting older

My dog loves this food!

[This review was collected as part of a promotion.] I switched my 8 year old pitbull/boxer mix to this food and she loves it! She has been a picky eater with some constipation. She is eating great, and having regular stools just a month later!

Great for my aging GSD!

[This review was collected as part of a promotion.] I finally found a great balance for my 8 year old GSD with skin and hip issues. I needed a food to support his joints, keep him lean and help his skin barrier against allergies. This food has done it all! I love the science behind all of Royal Canin's diet's and and thrilled to have found the one perfect for him!

Love it!

[This review was collected as part of a promotion.] My 9 yr/o Labrador Jack never leaves the bowl empty. The bigger kibble makes him take his time. Since he has some food allergies Royal Canin has never had any effects on him from the Puppy to the Senior. After 9yrs I still have people telling me he looks so healthy and love how soft and shiny his hair is. He also has healthy gums and teeth!

Couldn't be Happier!

[This review was collected as part of a promotion.] My GSD has been eatting Maxi 8+ for over a year now. His skin and coat look great! He loves this food and we couldn't be happier with the results we have seen

Dog loves it

[This review was collected as part of a promotion.] I have a 10yr old German Shepard and just getting him to eat can be a pain sometimes. I changed his food numerous times and he’d be interested but then turn away later but with this one he enjoys all the time. The kibble is a great size since he like to swallow his food it slows him down. I also like that it has joint supplements and is catered to my senior dog.

Great quality and happy pups!

[This review was collected as part of a promotion.] I have been feeding my oldest dog Royal Canin ever since his vet recommended switching food brands to help with his skin allergies. Sure enough, his skin cleared up and he is as happy and energetic as ever! He is 12 now and the aging formula seems to give him all the energy he needs and keeps him at a healthy weight. I’m definitely glad I was introduced to Royal Canin.

Great for Joint Health!

[This review was collected as part of a promotion.] My Shepard-Lab mix (we think... DNA results are pending) has been on this food for about 8 months now and she’s doing really well! She’s going on 12 years old and there’s not a better food we’ve encountered that gives her the mobility that this food has. She takes a glucosamine supplement on top of it that she’s been taking for years and the two combined does wonders for her. I would recommend this for anyone with an arthritic, geriatric dog.

My dog loves it!

[This review was collected as part of a promotion.] My dog was picking at her old food, and now she scarfs this food down! I’ve really noticed an improvement in her coat quality!
