Do you like roulette? We’ll be honest — there’s a chance your dog may like this product and enjoy the taste, but the majority of pets will not; and when they don’t, they’ll never go near where you spray this stuff again! Not only will your dog’s bark officially be worse than its bite, but what truly makes our Bitter Anti Chew Spray different is this: it’s made from the most bitter substance on the planet and is devoid of alcohol and propylene glycol (potentially toxic to the kidneys & liver), which means your pup can sink its teeth into your favorite stuff for the very last time without it gnawing away at your conscience. It doesn’t get any bitter than this! Gentle. Effective. Safe for most surfaces.
