I have a 14-week old Shepherd mix puppy who definitely pulls on his leash when we walk, but that's as to be expected at this age, so that's actually not why I was thinking about getting him a gentle leader.
He's got a bigger problem of eating literally anything loose on the ground; I'm attempting to train him out of it but that's obviously going to take some time. While that's happening, I was thinking about getting a gentle leader attached to a harness just to gently keep his head up. But I obviously don't want to do anything that would hurt him or cause any future problems so I wanted to see if this was a good idea in general -- and if it's not, if it's something with regards to his young age or not?
