This sturdy canine is a cross between the Bulldog and the Mastiff. Originally bred as gamekeeper dogs, this breed is now popular as a pet. This heavily illustrated book avoids technical language while offering sound advice and reliable information to current and soon-to-be pet owners. Written by animal specialists, veterinarians, and trainers, the titles in this series focus on pets of all kinds--different dog and cat breeds, birds, fish, reptiles, small animals, yard animals, and even exotic pets. All ''Pet Owner's Manuals ''are filled with high-quality photos and instructive line art.
