You can try supplemental feeding with dog milk replacer and keep him warm and next to the mother and others if possible. Sometimes there is an underlying medical problem with the runt and in spite of your best efforts they do not survive. Dogs and other animals have litters with several pups because there is often one or two that don’t live. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Lucky.
