Dog park behavior stresses out dog owner

DEAR HARRIETTE: I go to a dog park weekly, and there’s one dog owner who keeps letting their dog jump all over me and my dog, even though I’ve repeatedly tried to set boundaries. I’ve politely asked them to control their dog, and I’ve even stepped in front of my dog to block the other dog when it gets too rough, but nothing seems to stick. Every time it happens, the dog owner laughs it off and says, “Oh, he’s just excited!” or “He doesn’t mean anything by it,” but I feel disrespected, and my dog seems stressed by the repeated interactions.
