The Bluestem Oral Spray with Vanilla Mint flavour freshens your dog's breath - fast! Safe and effective, Bluestem attacks the harmful bacteria that cause periodontal disease. The difference is coactiv+, a powerful technology that uses only food-grade, scientifically developed ingredients to safely breakdown biofilm, where the harmful bacteria associated with periodontal disease multiply. The no-startle nozzle is easy-to-use allowing you to treat even the most sensitive of dogs. Just gently lift the upper lip and spray liberally on each side of the mouth, coating teeth and gums. For DOGS ONLY.
