Overview
Royal Canin Breed Health Nutrition Shih Tzu Adult is a chicken flavored dry dog food built specifically for adult Shih Tzus, sold in a 2.5 pound bag with a kibble shape designed for the breed's jaw structure.
Royal Canin builds its breed specific lines around a matched kibble shape as much as the ingredient list, and this formula is positioned for skin and coat health, dental hygiene and reduced stool volume and odor, concerns owners commonly raise with small, flat faced breeds like the Shih Tzu. At 2.5 pounds the bag is a small starter size rather than a bulk buy.
- Breed specific formula and kibble shape for Shih Tzu
- Chicken flavor, protein rich recipe
- Supports skin, coat and dental health
- 2.5 lb bag size
Who it's for
Fits owners specifically feeding an adult Shih Tzu who want a breed matched kibble shape and formula. Not intended for other breeds or for puppies, since it is built and shaped around one adult breed profile.
Strengths and trade-offs
Drawn from this product's published specifications.

Performance notes
