Hello, Boxerlover. I was the type of person who used to hate to see a dog muzzled. My story is a little long but you have to read it. My beloved Rottie, Kilo, started become really protective when we moved to the country four years ago. He seemed to think that everything and everybody walking by our house was going to harm us. One day this past January I tied him out. Less than five minutes later I looked out the front door and saw that he was loose. I opened the door and called him in. I looked to my right and saw my neighbor about 30 yards away with a look of terror on her face. Kilo had bit her. Fortunately it was winter and he only got her coat. Well, in Pennsylvania, there is a one bite dog law pertaining to "dangerous" breeds, so we had to have him put down. I can tell you without a doubt that if I had it to do over again, he would have had a muzzle on him that day. I used to hate to see a muzzle on a dog, but I would give anything to be able to look out the front door and see Kilo out there with a muzzle looking at me with those big brown eyes.
Good luck in whatever you decide and let us know how it's going.
