My husband and I have a 10 week old boxer. She is beautiful, fearless, determined and extremely smart. She has just scaled a baby gate with hard plastic criss-cross netting, that was leaning sideways against a wall like a rock climber using her "hands" and "webbed feet" and balanced herself on her hind legs on the one inch wide wood railing. Very scary and impressive at the same time. I hope to find some helpful advice on my puppy at this site.
