Already seen that. All they show you is when the *CURRENT* STANDARD was approved. They do not even tell you what revision it is.
The latest GS standard was approved 1978. The GS has been in the AKC since 1913.
We need a real history, and even the AB&TCC doesn't give it to us on their site. But their winners history indicates it was c. 1980. I know B&Ts were recognized when I was running around shows c. 1985.
