Our 4 month old pup tends to sleep 10pm - 6am when we've been getting him up, taking him in the garden for the toilet and then for a short walk then home for breakfast and he's back in bed from. 7-10ish. However the last few mornings when we go to him at 6am he just doesn't want to get up and no amount if coaxing will persuade him. He's not poorly or in pain, everything else is fine. What would you do? Enforce the routine (which fits in with our family / work) or let him stay in bed?
