Extra small dogs are susceptible to constipation due to their long digestive tract, compared to their small body size. This is due to increased fluid to being removed from the colon, leading to dry stool. X-SMALL Adult is formulated with highly digestible proteins and an optimal fibre balance (including psyllium) which help to regulate and ease intestinal transit. Low Indigestible Proteins (LIPs) help to limit the indigestible protein reaching the colon which becomes fermented by the bacteria and this helps to improve stool quality and odour.

An extra small dog's skin and coat are a reflection of their overall state of health. X-SMALL Adult™ is formulated with anti-inflammatory omega 3s (EPA and DHA), vitamin A, biotin and highly digestible proteins to help contribute to a healthy skin and coat.

Quality food from a trusted brand

[This review was collected as part of a promotion.] I have been feeding my small dog Royal Canin for some time now and am always impressed with the quality of the food and my dog never turns it down. The pieces are a nice size for little dogs, the food is healthy for my dog and my vet backs it. It’s a win for me

[This review was collected as part of a promotion.] I received Royal Canin X-Small Adult dog food in the mail about a month ago . My little guy is super picky when it comes to dry dog food . I have tried numerous brands with him. He will actually eat this brand with no issues at all . I like this brand because they don’t have fillers and artificial flavors in their dog food .

My pup eats this with no topper!!!

[This review was collected as part of a promotion.] I love that they've got real ingredients packed into these tiny bites. It's like a gourmet meal for my dog every day. I've noticed he eats this kibble WITHOUT a topper, which means he LOVES it. i also like the packaging because it keeps the kibble very fresh. If you've got a little or big pup with a big appetite for deliciousness, this dog food is the way to go.

Great food

[This review was collected as part of a promotion.] My small shitzu loves this food. It’s the only dry food she will eat. I started using it as snacks to train her. Now she eats it for her meals. Royal canin has never let us down. We have recommended to other dog moms and dads. We will continue to purchase and use.

[This review was collected as part of a promotion.] My dog definitely seems to take to this particular brand of dog food. It does not have a horrible funky smell to it and has her full of energy and being in a healthy state . The bag zipped up and I loved that to.

My chihuahuas LOVE it!!

[This review was collected as part of a promotion.] My 2 Chihuahuas have spoken! They absolutely love the size and taste of this Royal Canin x-small dog food. I started mixing it in with their normal dry dog food and they pick out these kibbles and leave their regular food behind. I love that it's formulated for their size and good digestion. The extra small pieces are so great especially for my Nigel as he only has 4 teeth. These are great for him. They will be getting this great dog food from now on. If they love it, then I want them to have it. So happy to have found a great nutrional food in a tiny kibble.

Buddy loves it

[This review was collected as part of a promotion.] I got this for my Cocker Spaniel Buddy. He really liked it! So much, he would eat it out of my hand, off the floor, in his bowl, pretty much any place. The size of the nuggets we just the size he liked.

Great food for small and older dogs

[This review was collected as part of a promotion.] I have a shorkie who is a little over 8 years old and she loves this food. She has some teeth and gum issues and needs soft and small foods. This dog food mixed with her wet dog food makes the perfect combination. The small bites makes it very easy for her to chew. We used Royal canine for our bulldogs and now we are using this food for her. We trust the brand and our dogs love it!
