Because, by the owner's admission, it is dog aggressive, and as we all know, the world is populated by idiots who don't control their dogs. Thus muzzling the dog aggressive dog is the only reasonable course of action. My dog aggressive one is never out without a muzzle because it's up to me to make sure he doesn't get himself in trouble when somebody's loose dog approaches him
It’s far from a ‘reasonable course of action’ to muzzle a dog just because it’s dog-aggressive. How would the Doberman defend himself if attacked by an off lead dog? Doberman could end up dead thanks to the muzzle!
I have a dog-aggressive dog who is ALWAYS on a short lead in public. He’s a rescue who has been attacked many times by other dogs especially bull breeds. Thanks to his size and quick reactions mine always gets the upper hand when attacked.
Though I worry about him eg what if a pair of dogs attack him or when he gets older, will he be as adept at defending himself? We walk him on private land as much as possible but to get to that land we often pass through areas with off lead dogs. Most dogs have enough sense not to approach an unfriendly or scared dog. Those that do get in his face or jump on him learn a swift lesson (as do their owners).
Muzzling him deprives him of his ability to defend himself if attacked. His safety is my priority.
I’m not going to muzzle him just because people don’t train their dogs not to approach a dog on-lead. I try to drive off-lead dogs away if I see them approaching, and shout to the owners to recall, and mine will bark and lunge if the dog keeps coming.
It’s not my dog’s fault he’s a rescue. He’s only aggressive to dogs never to people. I’ve spent a fortune on residential courses and training. He has a red warning harness. If some fool lets their off-lead dog jump all over him he will react aggressively and (as I have explained to these owners) I’m not responsible for any vet bills. They’re at fault for letting their untrained dogs get into his face!
