Therapy Dog or Service Dog

Sooooo, I'm working a German Shepherd that is in training to become a service dog.  He has a Service Dog vest and I'm in a store shopping for shampoo.  As I'm standing with a bottle in my hand reading the back label, an employee approaches me and asks "Is that a seeing eye dog?"  My answer- "Yes.  He's reading this shampoo bottle to me telepathically."
Here's what you need to know about Service Dogs and Therapy Dogs and the difference between the two...

1.  By definition, a SERVICE DOG performs a task that the handler is not capable of doing for himself.  Seeing, hearing, alerting of medical conditions, retrieving, stabilizing, etc.  A service dog should be wearing I.D. and is allowed by law into any establishment.  Cesar Millan- I love you- but Junior is NOT doing anything you can't and shouldn't be given Service Dog status just so you can fly with him.
Interacting with a service dog:
Do not stare.
Do not avoid eye contact.
Do not pet a working service dog.
Do not ask the handler "What does he do?"  Rude 101.  That's like asking someone in line at the pharmacy what they are getting medicine for.  It's none of your business.
If you must- simply compliment the handler on having a wonderful dog.  Keep moving.

2.  THERAPY DOGS only need to be well behaved and obedient.  Their main task is to provide stress relief and comfort by simply being a dog.  There are several organizations that provide certifications for therapy work but it is not required.  Certification is merely proof that the dog has demonstrated his ability to behave appropriately in public situations and some organizations insure their certified dogs in case of the unexpected.
If you ask first, it's usually quite fine to pet a Therapy Dog.
   I get a lot of requests from people wanting service dogs, who do not have a medical prescription or a disability for which the dog can compensate.  Many people simply feel better if their dog is with them and would like to be able to take them every where they go.  I wish we lived in a world where that was possible, but right now it's just not legal!
More and more businesses are allowing you to bring you dog.  If you do take your dog in these places, be sure they are well behaved and do NOT leave a mess!  I always make a point of thanking the owner/manager for allowing me to shop with my dog.  I tell them when I have chosen to make a purchase from them rather than a competitor based on the fact that I was allowed to bring my dog in- especially in the summer when it's too hot to leave them in the car!
