Are dogs allowed

I believe all service dogs are welcome any where

Yes

Yes I have seen all kinds of dogs not just service dogs.

Only service animals are allowed into businesses that carry any kind of food (I too see people sneak in very little dogs)

Service dogs allowed

Service dogs.Legally. People do sneak in some little dogs.

I've seen people bring little medium size dogs in places like Wal-Mart. They are discrete in some cases because I think it's against health code. I love Doggies.
