We adopted Ed in November and have taken him to two dog parks. Both times, he tried herding the other dogs. The first time the other owners were pretty understanding and didn't mention it. The second time, Ed was following a dog as it was chasing a ball. He wasn't interfering, just following the dog. I stopped Ed for awhile (I had kept his leash on him) to see if he would be interested in another dog, but he just wanted to follow the one dog. Apparently the owner didn't like it and left. After seeing that Ed chased an owner away, I don't feel that Ed is welcome at dog parks. It is his natural instinct to herd, there isn't much I can do about that. So, it seems Ed will not be going to dog parks. Unless anyone has ideas around this.
