Uno is a terrific dog whose negligent owners never taught him as a puppy that mouthiness is not a feature prized by humans!  He just needs a "Miss Manners" to show him that toys are suitable for nibbling, but not fingers.  A dedicated or bull-terrier-experienced owner will find it easy to re-direct his oral fixations.  He is about 4-5 years old, neutered, and up-to-date on vaccinations.  He is your typical happy-go-lucky, exuburant, male bully.  He is not dog aggressive, but would benefit being the only dog for the time being.
