Is My dog too friendly?

No such thing as a too friendly dog. I'm glad to hear that your dog is quite innocent and doesn't have a mean bone in its body. I think a lot of dogs are quite like yours but don't have good enough owners that the dog becomes disrespectful to others over a period of time.

My dog was the same way too, except if she would be eating and someone wanted to take her bowl away. That's the only time she'd be upset with anyone. Don't mess with her food!
