The Bull Mastif is a relatively new breed of dog that came about only about a century ago. This dog is the culmination of crossing a bulldog with a mastiff, seeking to carry over the best features and traits of both. The wrinkly face of this canine seems to be always stretched into a smile. Indeed, the Bull Mastiff is usually a friendly, outgoing dog. However, the size - more than 100 pounds is common in an adult male - and protective nature make it a natural guard dog. Show off your loyalty to your canine companion with a Bull Mastiff T Shirt. Or choose a Bull Mastiff Women's Scoop Neck T Shirt as a gift for that woman who loves this breed.
