As a dog and animal lover, I 100% agree. I can understand companion and service dogs, but the squares do become very easily over crowded. Along with the possible stress on the poor animals, my daughter gets so excited to try and pet them(she knows not to bother working dogs), but a lot of time, unfriendly owners turn their nose up at her when she compliments their dog or asks to pet. It's sad
As far as businesses go, my mom had a dog that she considered her "service dog"(she was getting him licensed when she passed away) and took him everywhere. When my mom was sick in bed, we would trick him into getting up to go outside by telling him we were going to Lowe's lol! He loved going to visit Lowe's and riding in the cart, loved the attention he would get. And that's really the only time he would get out of the house, as he was always by my mom's side, would never leave her.
At appropriate businesses, totally acceptable if they're properly leashed or in the carts.
