Took to the vet she said yes the pup was week low heart beat. He was nursing and doing great, when I came home I noticed that the female was full and the male was skinny , Not been eating. I took and pup him on moms chest , he tryed to nurse but just kept droping his head after a minute looking around for another. but still really not sucking. I hear reaspy lung. but vet did not seem to hear it. She gave him clavamox, Said to keep him warm he is on a heating pad. Gave him some nutrical and expressed moms milk and gave him 1cc. Any other things I should to to help him survive??????Blondschillin
