This is what a dog under control looks like: returning to me after I call him.
Here's the deal: If your dogs are coming after mine, regardless if one is wearing a muzzle, I'm going to say something to you. I've taught my dog not to react the way his instincts told him to, by barking and lunging at dogs when he's afraid of them, and instead use other means of communication to tell other dogs he's not interesting in engaging with them. It's now my duty to protect him when he's doing the right thing, and your dogs aren't. If your feelings get hurt in the process, too bad. My dog—and his training—is more important to me than your feelings.
Today at Black Park there were lots of dogs, since it was a nice Bank Holiday Monday. Most were fine; Sparky goes wide on the path or swerves into the brush to avoid meeting them face to face; something he (and most dogs) consider rude.
But then two boxer-like dogs come toward us, one wearing a muzzle. The white one goes after Sparky, who has swerved into the brush, so Sparky comes toward us, looking for help. That's when the other dog joins in the "fun", and both dogs chase after Sparky, who I've motioned to run forward in an effort to avoid confrontation. I also put my hand out toward the two boxers, hoping to halt their progress or at least alert their owner to the fact there's a problem here: I don't feel comfortable around large dogs any more than Sparky does, frankly, especially when I see one has already been deemed aggressive enough to wear a muzzle.
When the dogs pursued Sparky, I told the lady to call her dogs. At this point, I was a bit angry that she hadn't already done so, as anyone else would have immediately if they noticed their dogs becoming too interested in another dog who was clearly trying to avoid them. She shouted that he was wearing a muzzle. "I don't care; my dog doesn't like to be chased!" I replied.
Then I told her she needed to teach them recall, since in my experience, the number one reason owners don't recall their dogs when necessary is because they know they can't, and they want to avoid embarrassment.
After this she called me a stupid bitch, and I just laughed. Because she's the one who's stupid. If your dog is wearing a muzzle, there's even more reason to teach recall: One day a dog will take offense to your dog's rude behavior, and will respond with a bite. Or two. Your dog won't be able to reply with his teeth, which is going to make him pretty angry, and more likely to snap the next time he's out without a muzzle. A dangerous situation you've created by not keeping your dog under control—and by this I mean preventing him from practicing rude behavior around other dogs or people.
My number one loyalty is to my dog, not to your feelings. I'm also American, and I wasn't bred to avoid confrontation the way so many of your fellow British countrymen are. I will tell you off next time you allow your dogs to chase mine, and publicly embarrass you if that's what it takes. I'll also be happy to explain how you can teach your dog recall: it's not hard. If I can do it, anyone can.
Your dogs will be a lot better off, and so will your feelings.
But if it makes you feel better to call me a stupid bitch, go right ahead. I've been called worse when defending dogs in your country.
