How many dog breeds are there in the US?

There isn't a definitive answer to how many dog breeds are in the US. This is because:

* The American Kennel Club (AKC) recognizes 190 breeds, but this list is constantly changing.

* Other kennel clubs, like the United Kennel Club (UKC), have their own lists, which can include breeds not recognized by the AKC.

* Many mixed breed dogs exist, often with unique combinations of traits.

* New breeds are being developed all the time.

Therefore, the number of dog breeds in the US is constantly fluctuating and depends on which source you consult.
