One of our puppies isn't doing so well as the others and it's got me worried. She's the smallest of the litter but up until yesterday seemed to be doing well. I'm weighing them every day so that I can see how they are doing and this little one has lost 10g between yesterday and this morning Any suggestions ?? btw.. we've offered her a bottle but she won't suck, we've been rotating her on the teats but again she won't suck.
