From dogs with kidney stones to small dogs rescued by shelters, this dry dog food has proven to be high-quality due to its results.
Vets often recommend it for allergies and certain health problems in small dogs. However, though chicken or beef should always be the first ingredient of a healthy dog food product, corn was added to this product recently. This is unfortunate, as many dogs develop digestive issues when fed corn-based feed.

  • Helps in maintaining metabolism
  • Good for dental health
  • Contains a mix of vitamins and antioxidants


  • The new formula may cause diarrhea and other stool issues

Whereas Royal Canin’s small breed dog food may have been effective in helping smaller dogs with health issues in the past, and many dog owners still use it, you may want first to take a look at whether your dog can handle corn or not.
