Our Corgi loves Royal Canin

We switched our pup from Royal Canin puppy food to adult food without any issues. He loves meal time and his weight had been great.

Liquid poops & bad farts

This food has given my dog so weird stomach issues. Her poop is runny and she has really weird smelling farts. I do not recommend this.

Royal Canin medium adult food.

I have fed Maggie several dry foods in trying to find the right one. I started with the one her breeders used. She ate it but was not excited about it. When it was recalled I tried another. After research I decided on Royal Canin. So far she loves it. I do feed her some fresh food as a topper on her evening meal. She likes dry food so I thought I would go with what I felt was the best.

Trash ingredients

I won’t feed my dog this food. I received a bag after fostering to adopt. For the price of this product, you would think the ingredients were better…. Normally the ingredients are listed in order of amount in the product. The first one is brewers yeast…. Although this product has benefits large amounts of it is not. The second is chicken by-product, I feel enough has been said about the trash ingredients. I don’t even want to donate it to the shelter.

Even more tasty than the delicious Canin puppy kib

My puppy just turned one and we bought the first bag of the Canin adult food. I didn't think he could love his dog food more than he loves the Canin puppy food but he proved me wrong...the adult food is even more delicious.
