We share the same dream!!! It is my dream to start a Doggie Day Care in the Pittsburgh area with many of the same ideas you expressed. However, I would also do obedience training as an additional service.

If this is your dream then GO FOR IT!!! It is going to be a little more difficult for me since I am already in my 40's and have financial responsibilities that prevent me from abandoning my current job in order to pursue something that is percieved by many as a risky endevor vs a stable environment.
