Oh Smuttly, you are too darn cute!
I agree that harnesses are the way to go. Winston scratches at his, but he's learning to love it. Molly knows to tolerate it because it means we are going for a walk! If he is a puller when he is older, look into the Sporn harnesses (they're available at Petsmart). Molly pulled to the point that it hurt me to walk her. Sporn harness stopped it the first time out. But I didn't resort to that until she was about 6 months. Winston will need one soon too. Ugh he is strong at 4 months (and 30 lbs).
