Oh, and I forgot to say that you should check the access laws for your state. Many states have or are going to pass laws that allow you to take your SDIT (service dog in training) almost everywhere so that you can actually train him/her in public. Otherwise, it's a bit hard to expose them to elevators, (never use escalators, their pads can get pinched and will bleed), stairs, crowds, etc. Good luck training your dog!
