Royal Canin Breed Health Nutrition Yorkshire Terrier Adult 8+ can give your senior Yorkie the tailored, complete, and balanced nutrition he needs. This formula features an exclusive combination of antioxidants to help support healthy aging, and has an appropriate, 15% lower phosphorus level than Yorkshire Terrier Adult to help care for his kidney health. It also delivers biotin and omega-3 and -6 fatty acids to help maintain a beautifully soft and luxurious coat. Plus, the small kibble shape and size help reduce tartar formation by encouraging your older Yorkshire Terrier to chew, and this kibble can be softened with warm water, which can bring out the aroma and allow for easy eating.
