Fantastic article, I loved it and can totally relate!!
We don't have dog parks where I live, but Kodi has to work and earn off leash playtime with my sister's dog or a swim in his pool. He's learned that dragging me into the backyard because he wants to play isn't allowed, but heeling, giving me eye contact and sitting or laying down when I ask will earn him off leash fun. And that just because we go in the fence doesn't always mean he's going to get to be loose either.
The funny part is that people sometimes look at me as if I'm being mean because I don't give in and let him do what he wants! But think that they're being wonderful doggy parents because they let their dogs do whatever they want, when they want including running the neighborhood! No wonder their dogs stare longinly at my sister and I when we walk and train our babies.
