I had a GWP for 12 years , first trained to work with the hawk. but after i got rid of the hawk she would work anything. Not like a spaniel or terrier and bush even if nothing in the cover, if she couldn't scent anything in the bush/cover she wouldn't work for nothing.
Seen her get on belly and crawl throu some really thick cover , and if using her on rabbit shed point giving me /mates time to prepare to shoot.
Fantastic guard dog, and great with my kids ( she wouldn't let no harm to the kids )
Depends on how you bring them up
