Help! One Week In With 14 Week Old Puppy. We Can't Get Him Outside Quick Enough. Already Messed Up (boy Now That Fits!) By Rubbing Nose In It, Etc, So Now, Is It Too Late To Try The Crate? I Bought A 3 Ft. Adjustable Pen (no Top) And It Worked One Day, But He Can Climb It, So Should I Buy A Crate? Also: How Much Should A Puppy Eat?
