Fido's Chew Stop Spray is a bitter-tasting training aid for dogs and puppies that chew furniture, shoes, plants, and other household items they shouldn't. A few sprays on the target surface make it taste unpleasant enough that most dogs lose interest quickly. Safe for use on fabric, timber, and plastics, and suitable for puppies going through the teething stage as well as older repeat offenders.

The active ingredient is denatonium benzoate at 200 mg/L — one of the bitterest compounds known, but non-toxic and odourless to humans. It works on contact rather than through scent, so the deterrent only kicks in when the dog actually mouths the item. Available in a 200ml bottle for spot use around the house and a 500ml bottle for owners covering more surfaces or dealing with a persistent chewer.

Owners reach for Chew Stop when redirection and chew toys alone aren't cutting it. It gives you a way to protect specific items — a couch leg, a skirting board, a favourite pair of shoes — without punishment, while you work on training the behaviour out.
