Pet Dental Water Additive

Oxyfresh 456 is a 16 oz liquid supplement added daily to a dog or cat's drinking water. It targets plaque, tartar and bad breath without brushing. The formula is odourless and tasteless so even picky pets accept it. Veterinarians have recommended the brand since 1984.

Daily Use Practical Limits

The additive only works when the pet drinks treated water each day; animals that share a bowl or prefer running water may receive an inconsistent dose. It reduces new plaque and tartar but cannot remove heavy calculus already bonded to teeth. Severe periodontal disease still requires professional veterinary cleaning under anaesthesia.

Check Before Ordering

Confirm your pet has no known sensitivity to stabilised chlorine dioxide, zinc acetate or chlorophyllin-copper complex. Ensure a fresh 16 oz bottle will be used within a reasonable period after opening to maintain efficacy. Verify the cap measuring system suits the volume of your pet's water bowl.
