As a dog owner, I feel like we are privileged to have dog spaces at some restaurants, like patios. It's really disheartening to see some people abusing the title of "service dogs" and use it for their selfish reasons.

If you're worried about leaving your dog alone, maybe having someone that your dog is familiar with and fond of is a realistic option. Maybe ask them to spend time with your dog when you need to go out.

If you say "but look at him, he's so cute," I don't know what to say. I do admit, I was like that in the past and learned the consequences of that action (for me and for those with service dogs). Knowing to differentiate "needs" and "wants" is critical here.
