1. Staffordshire Bull Terrier
The Staffordshire Bull Terrier is a cross between the modern-day bulldog and the old English Terrier; a breed which is, sadly, extinct these days. The breed was developed to participate in dog fights, which are thankfully illegal these days. Staffords can live up to 14 years. The breed got official recognition in 1935.
A Stafford is an intelligent, brave, balanced and loud breed. It is very obedient to the master of the pack and they tend to be very tolerant to children. However, you should be careful with other male dogs around them. No matter how good you socialize them, they can have aggressive tendencies towards other male dogs.
If you are looking for a dog which is a cross between a guard dog and a companion dog a Stafford might be the perfect breed for you! I do recommend the Stafford only to people which already have some experience in raising dogs. You do need to invest a lot of time, patience and love in this breed. The training of this dog must be done really consistent and firm, if you don’t do this they will become the leader of the pack and they will control you instead of the other way around.
