I’ve hunted over both quite a bit.
As far as high strung, most labs are way more wound up than the average griff.
I love labs, but they are like retards on meth. Lol.
Only gripe I have with a wpg is the coat takes some maintenance. You can spend some time getting them cleaned up after a day busting brush.
In the field my griff is tractable and thorough. My buddy’s lab is a rocket.
When it comes to retrieving, it’s not a contest. My griff loves water retrieves but can’t keep up with the lab. The lab will retrieve wads if your shooting clays for fugks sake. 😂
At home my griff is mostly chill.
