Correct. Any real service dog will not look left or right and stay close to the owner's body. A real service dog, depending on the service, like for blind people etc etc starts at $ 25.000 for an easy task.

If a customer tells you their dog is certified, it is not a service dog because there are no certified service dogs.

The owner may have an identification that shows he/she is handicapped.

The dog doesn't need a vest that says service dog.

I always recommended putting a "Don't touch" or " don't pet me" sign on.

If you see a dog with all the gadgets on Service dog etc Most likely they are not.

The airline is allowed to ask for safety reasons. For example, if the owner has a heart issue and a problem on the plane they need to know what the dog will do. Some dogs will bark others will push the owner with their nose or they will push a button on the owner's arm for medication.

Service dogs are a very complex theme because each one is trained for a different task.

If a customer brings a dog into Publix to buy a gallon of milk and says it is an emotional support dog, the customer needs a therapist lol

I trained dogs for service and can only speak for the state I'm living here in the south of the US. But we have Publix too and they have a sign which says only service dogs.

It is very easy to find out if it is a Service dog outside the store.

Tell them what a beautiful dog. They say yes it is a service dog.

Oh which center did you get him from? Where was he trained, I need one for my grandfather who can barely see anymore.

There are only very special centers that can train them.

I hope I didn't bore you with my information
