I just recently got a dog that is hound/black lab. He's kind of crazy, but hey, he's still a pup. I had some hemp string laying on the ground and I noticed that he really enjoyed chewing on it. I know that I have chewed on hemp before because I tend to chew on stuff out of habit, but is it okay for him to chew on it? Just wondering because if I made a chew thing for him out of hemp it would keep him occupied for awhile. Thanks in advance for your help.
