1. I can't count the number of times a dog owner has told me, "My dog won't hurt you, he's just excited!" Meanwhile, they're actively struggling to stop said leashed dog from lunging and jumping on me. No, if a dog owner has to fight to stop their dog, that dog is not under control. They both need obedience training. If it keeps happening, that's an owner problem, not a dog problem. (It's especially bad when I see a child who's obviously too small to keep the dog under control.)

(And, the smallest dogs are the worst. They're usually off-leash and spoilt rotten.)
