That’s what my friend tells me. Everything is different between the English Labs and the American Labs trials.
She considered it a honor to be asked.
Awhile back, our Hunting Retriever Club magazine ran a special feature on 4 or 5 UKC Hunt Test dogs who were invited to Britain to run in a field trial there. These were top UKC dogs and they did very well - although some of the dogs were puzzled at first by the different conditions, they thought it through and noodled it out.
The AKC field trials in the U.S. have gotten so rarified that the UKC started doing "hunt tests" as being more of a realistic test of hunting conditions that a real hunting dog might actually encounter. And the hunt tests got so popular so fast that the AKC had to start offering them too!
I don't do field trials - I'm not good enough - I do hunt tests. My dogs really enjoy it.
