My friend had (recently passed away) an outstanding hunting lab. That dog was just super in the upland field and duck blind, and was a sweetheart as well. Just an intense hunter though. I mean, really intense.
About 2 years ago, a GWP was making the rounds in the neighborhood, hopped his fence, and... Well, now my friend has a GWP/lab.
It's a sweet dog, but I swear it is the oddest looking dog I have ever seen. It has a build somewhere in between a lab and wirehair. Coat is all black, with the length and texture somewhere in between a lab an wirehair. It's got a beard, shaggy feet, and shaggy tail. I think he should have docked it, but it doesn't really matter because...
My friend figured it would be a good hunting dog of some kind, so he took it hunting many times. It is his only dog now, so he figured it didn't matter much if it pointed, flushed, or just kinda-pointed birds. Well, it turned out to be "none of the above". It is an absolute turd in the field. Shows no interest in hunting whatsoever. It just follows along and watches the other dogs hunt, watches the birds... It just kinda trots along, happy to be with his master, but not interested in participating.
Anyway, I'm sure 100 people can post 100 stories about all the outstanding mixed breed dogs they've hunted over, but my friend is stuck with a real misfit. By the age of 2, you would think the dog should have showed SOME interest at least once if it was ever going to come around.
So I'm not trying to rain on anybody's "hybrid super-dog" parade, but I would suggest that a lab/wirehair is probably a bad cross...
