Mambo, a seven year-old neutered Jack Russell terrier mix, was originally found on the streets as a stray. He lived with — and was treated like a king by — an older couple for a few years, until he showed aggression toward their grandchildren. Now Mambo is an old, homeless mutt with a really spoiled attitude. Mambo is currently at the Enschede Shelter in Holland, where one of the caretakers, Rudd, is very concerned about his future. Mambo’s attitude is keeping him from being adopted. He’s stressed out and has become destructive, and is very unpopular with the other dogs.
