Snake bites, puppies and a grumpy old dog.

So I'm sitting here on BYC and I hear one of my 10 new puppies scawl, do I run outside and begin the seach for the injured puppy. All I find is 6-7 black fuzz balls under the AC unit under my window. After I put them away, I'm walking back to the house and see mama dog (Molly). She got her nose in the mouth of a copper head or something and she looks like the target dog, she's a choco. lab. I'm quite used to snake bites in dogs, as my jack russel terrier mix is a snake dog, she normaly kills all of the snake around my house, so of course she gets bitten. Her record is 13 times in one summer, so normaly she gets bitten about 5-6 times a year, but ether she has gotten more sneaky or it just doenst affect her anymore. Anyway, the pups are being weaned but are not totally off of mama's milk. Can she still nurse them or will the venom affect her milk as well?
