Hi guys looking for some help we have a 7 month old border collie , an amazing dog great temperament, how ever , sleeping is a different story , no matter what we do how late we go to bed , how late we walk him or how many times to tire him out he will bark at 4am or 5am or anytime inbetweene, I know hes only a puppy , but is there anyway we can get him to sleep a bit later ?
