American Bulldog/Boxer Hybrid or Mixed Breed dog
The American Bull Boxer is a designer or cross breed dog.
What is the American Bull Boxer?
It is a cross between the American Bulldog and Boxer dog.
Mixed breed dogs tend to be healthier than full blood dogs and this is why designer or hybrid dogs are quickly becoming as popular as many of the AKC registered breeds.
There are many registries where you can get registry papers including 5 generation pedigrees also. The best advice I can give you is study each individual breed and determine both the temperament and characteristics in each of the breeds.
Most of your designer or hybrid breeds come in many different sizes, including: Teacup, Tiny Toy, Miniature and Standard.
It's best to ask the breeder the size and weight of the parents to get a better idea of what size the puppy your interested will be as an adult. It is harder with the mixed breeds to determine an exact adult weight.
