We just got our 4 month old boxer pup, she is an angel. We have her in a kennel during the day. Our problem is we work from 8-5 and the pup cannot wait that long to poop. It has been messy. Is it O.K. To hold off on feeding her until we get home at 5:00. My husband can get home aroung noon or 1:00 sometimes to check on her but even then she has an accident.
