I highly recommend muzzle training to everyone. A dog can bite just as quickly out of aggression, as they can out of fear, as they can out of pain. In my car, I have 2 emergency muzzles in my first aid kit because a dog in pain (even the sweetest dog on earth) is still capable of biting.
For all my reactive or aggressive dogs, I require muzzle training. It’s a great safety tool that can prevent a lot of heartache. Not only is it a deterrent from being approached by strangers (and dog lovers) but it helps assist in behavior modification.
