How can I get 4 week old puppies to eat solid food? Please help!

Thank you so much! I didn't even think about their toenails. I'll have to do that when my husband gets home. It's tough to keep track of ten puppies. They look like rottweiler/border collie mixes. Mom is about the third of the size of a rottweiler, but has the same markings. We're fostering through the Humane Society, so they have given her some vaccines, but not sure what she went through before that. We're not even sure what her name was. We call her Mattie and she seems to respond well to it. I must say, I'm intrigued with the sprite idea. Maybe I'll give that a shot, too.

Thanks Everybody!
