* "K9" refers to dogs in general. It's short for "canine" and is often used in law enforcement and military contexts.
* "Breed" refers to a specific type of dog. A Bull Terrier is a specific breed with its own characteristics.
While Bull Terriers are dogs, and therefore canines, they are not a separate "K9 breed."
Here's how to think about it:
* K9: A broad term for any dog used for work, training, or specific tasks.
* Breed: A specific type of dog, like a Bull Terrier, German Shepherd, Labrador Retriever, etc.
Bull Terriers can absolutely be trained for work, but that would make them working dogs, not a specific "K9 breed."
