Henry has qualified for the national championships each of the past three years and this was his first title.
Butler said Henry also is an outstanding retriever.
“He is one fine field dog,” Butler said. “He loves duck hunting and is just crazy about pheasant hunting. He has been out many times doing both of those. That's a good break from training.
“He's fun to watch. That is the best part of the duck hunting with him, just watching him go get ‘em. He just does everything at a high rate of speed.”
In addition to this year's national championship, Henry became a Master Agility Champion in 2012 by finishing first in more than 60 agility competitions and earning second place in more than 30 more.
But in many ways Henry is very much like any other Labrador, Butler said.
“He is a tail-wagging, loving Labrador,” Butler said. “It's an incredible honor to work with a national champion and to bring a title to Oklahoma, but Henry obviously enjoys his treats and a good scratch behind the ears much more than the honors and accolades.”
