certainly was not the smartest dog i have ever owned but he was the most fun! we both grew older together and knew each others limitations. i got him when he was approximately 1-1 1/2 years old, he was a stray that had been hit during rush hour in traffic (couldn't find owner, tick infested and no collar or id). he enjoyed being held and swung back and forth, this would give him a burst of energy just as if he was still a puppy.
i miss this dumb old dog and won't forget him!

Looks like he had some Corgi in him. Sorry for your loss.
