American Bulldogs are one of the few dog breeds that can claim that they were truly developed here in America. This breed is large in size and is very strong and muscular with a strong jaw. There are two types of this bulldog, the Johnson Type, and the Scott Type. While the differences in the middle of these two types is mostly gone now, in the past they had some positive differences.
The American Bulldog is derived from the English Bulldog. The two population mainly responsible for how this breed appears today are John Johnson and Allen Scott. These two men worked together to buy bulldogs and breed them, with the aim of construction a better bulldog.
Eventually the two split ways, but each kept breeding bulldogs on their own and therefore we ended up with two distinct types of American Bulldogs.
The Johnson Type is a large dog with a shorter muzzle. The Scott Type is smaller with a longer muzzle, but today most bulldogs are a mix in the middle of these two.
This dog has a short coat that is plane and very easy to care for with moderate shedding. They come in some colors with blue or merle being the most desired. They can weigh up to 125 pounds, so you right on want to have a lot of room for these dogs in your yard.
Unless very well trained it is not a recommended dog for new dog owners or for those population with small children or cats. These dogs can be very aggressive, so that is why allowable training and socialization is significant at a young age
As you can see the American Bulldog is not for everyone. If you have a large backyard and time to properly train them you can have a very loyal and cordial dog.
