I call Ace my Mystery Mutt or my SPCA Special, as that is exactly what he is. I got Ace from the SPCA in 2000 when he was 1 1/2 years old. They didn't know his breed nor did they have any history on him, but I am certain he was abused. He is such a good boy and has never given me a moment's trouble. In over eight years of lots of love of patience I have not been able to completely undo whatever was done to him. He startles easily and is very sensitive. He is also shy and timid around strangers (especially men) and sticks to me like glue. However, he is very gentle with children and absolutely loves other dogs. He may be 10 years old but there is still some puppy left in there yet! He is always up for a good chase, wrestle or game of tug-o-war. He also likes going to agility classes. Despite being the oldest dog in the last class, he showed those young whipper-snappers and was top of the class! He may not have the stamina anymore but he has the heart!
