Amber keeps coming out of the box for a while at a time. Is this ok. Pups are sleeping and heat lamp on so they seem content. Itseems as though she just wants to go and feed and clean then out. Is this ok. Some of the pups have found their voice and really yelp when they want fed or to cuddle up to another pup. This seems to get worse at night.Is this all ok. The other thing is Amber was eating when she was in box as long as I gave her a handful at a time. Now she is out for longer ther is not so much scope to do this and she won't eat from her dish yet. Don't know if I should start mixing tripe in food to tempt her but don't want to start this cycle all over again......HELP!!
