Hi,I be greatful for any advice. my yorkie gave birth through the night, sadly 4 of her 7 pups have died. She is very distraught, she is feeding 2 health pups but there is 1 more pup i'm concerned about. this pup had trouble breathing and i had to revive it, now she seems fine but mum wont let her feed and keeps rejecting her.I don't know wot 2 do for the best, should i take this pup away and hand rear it? I'm scared incase we lose this little one aswell.
