We bought a 10 week old maltese who was diagnosed with a liver shunt and had surgery. He can never have protein. He passed AKC Canine Good Citizen and passed the Certified Service Dog. He was privately trained and then tested. He is our precious Spencer who weighs 7 lbs .25 oz. He was born July 9 , 2009. When I freeze , I say feet and he begins scratching at my feet. Somehow it works and I stop freezing. On occasion that I do fall. I say help, if no one is around ,he runs over to the emergency box and presses the button . The monitoring station calls and if no answer, help arrives.
