Yeah it looks like they're huddling to keep warm. Maybe like Dotes said, and plenty of soft bedding, warmth is vital to their health at this early stage.

And check that mum is making enough milk, and can cope with all the feeding, even though she has enough nipples, it's demanding feeding so many puppies, she'll easily tire, and get sore.

All are so cute.

I agree Tracey they seem to be huddling together to keep warm, I know mine slept together but spent alot of time sleeping on their own.

Vet bedding is great for keeping them warm, do you have their weights from birth to now would be intrested to see how they are growing I was forever checking mine, drove my family mad with it.

Glad mum is also doing so well
