Hi,
I was reading at a park picnic table once when a pit bull came racing across the field with its owner chasing after it far behind. Two park workers ran to the table next to me and jumped on top of it, and, thankfully, the dog followed them, but ran by me first. I grabbed its collar, and, again thankfully, it stopped and waited quietly until it’s owner caught up. Of course, they explained that the dog was friendly, but it’s really frightening for many people to be chased by a dog. I had another instance where two pit bulls ran up to my young granddaughter. Again, the owner gave assurances of their friendliness when she caught up with them, but it definitely made me feel nervous having them approach unleashed. You can use a long leash in public settings which can give your dog some running space, but still give yourself control over whatever situations arise. Your dog looks like a great companion!
