Ocean Chew is sourced from marine Elasmobranch fishes namely Ray fish, Shark and Guitar fish. It cleans teeth, prevents plaque and reduces tartar. Ocean chews contain protein from Fish meat, Chondroitin sulfate, a prime natural ingredient for joint support. Our chews possess omega 3 fatty acids, which improves the skin texture, immune system, hair growth. There is no harm if the dog swallows a larger bit with an irresistible palatability stimulant.
