 Is that a spray or what is that, Dog Repair? Yes, that is actually a form of a pepper spray. You know, it's not harmful for the dog. The American Kennel Association and the Humane Society, they all approve of it. It's about 99.5% mineral oil and about 0.5% capsicum extract. So a little bit of pepper spray does no permanent harm to the dog and it lasts for about 15-20 minutes.
