American Kennel Club [SEP] History
In 1906, the U.S. Department of Agriculture ruled that any dogs imported to America who were not registered with the AKC would have to pay a duty charge; this was later changed in 1911, allowing any dog registered with a kennel club in its home country duty-free entry into the country. Soon after the AKC, CKC, and KC produced agreements that made any dog eligible to be registered with the club in its home country, eligible for registration in the remaining two clubs as well. In 1909, the group moved to New York and became incorporated.
