We adopted Pepper in July. We were told he was a Lab, golden and Great Pyrenees mix. According to his DNA profile, his father is a rat terrier and his mother is 1/4 chow. Interesting! He is definitely a chewer. He is also a great jumper. His favorite game is to jump up and try to knock his cup of kibble out of our hands! His canine sister is a greyhound. He definitely loves to give her a hard time too.
