* "Classic" American Bulldogs: These are the older lineage, with a more athletic build, narrower head, and longer snout. They tend to be more energetic and active.
* "Standard" American Bulldogs: This lineage is more recent and was bred for a heavier, more massive build. They have a wider head, shorter snout, and a more laid-back temperament.
These two lineages are recognized by different organizations:
* United Kennel Club (UKC) recognizes both "classic" and "standard" American Bulldogs.
* American Kennel Club (AKC) only recognizes the "standard" American Bulldog.
It's important to note that both lineages are considered American Bulldogs. The difference lies in the physical and temperamental characteristics they were bred for.
If you're looking to adopt an American Bulldog, it's important to research both lineages and determine which one best suits your lifestyle and preferences. Talking to breeders and rescue organizations can help you find the right fit.
