Mutt Mutty Beast by Sigikid
This is Mutt's story as written on his tag:
"Mutt Mutty was adored and pampered for many years. But then her owner, an extremely wealthy New York society lady, died of old age and left the not quite purebred terrier a handsome inheritance. But you can't buy love. That's why Mutt Mutty donated her money and is looking for new challenges - as a family dog, child replacement or in a retirement home. After all the little dog isn't a puppy any more either, but she's so cuddly!"
