I have a lab and a griffon. The griffon is not much of a shedder, huge difference from our lab. I got the dog as a started dog from a breeder in Montana at 10 months. She's been a challenge to train because she is both stubborn and sensitive. Not soft but unique in her personality. Not specific to the breed but they are different than labs to train. I learned started most mean to people out west - almost house broken
Mine will do blind retrieves and is dead calm and quite in the blind while duck hunting. In the field she has an excellent nose. Sweetest, friendliest dog we have ever had. We also have a GSP and if we got a new dog tomorrow it would be a griffon. As with any new dog find the best breeding you can find and or afford.
