Rash

Started this food at the advice of the vet due to crystals in urine. moving from the previous Royal Canin Veterinarian Diet Gastrointestinal Low Fat Dog Food. Mixed in in slowly with the previous and after a week when it got to over half this of this product, a rash appeared on my dogs coat and she began licking herself.

Great food!

I started using this food when I was told by my vet that Holly had crystals in her urine. This product has really helped her issue.
