Our pet oxygen regulator is easy to use with the portable oxygen canisters. The regulator is equipped with an easy-to-read oxygen gauge that shows how much oxygen is left in each canister. Start and stop the flow of oxygen with a flick of your wrist, and easily switch out oxygen canisters in seconds. You can leave the bulky equipment behind for our lightweight, portable oxygen canisters, which are great for on-the-go or for transport to your veterinarian or nearest emergency care facility.
