What do I do with these baby rabbits?

Our dog keeps finding baby rabbits. Have no idea where the nest could possibly be since we live in the country. The last one was probably a few days old. We fed it goats milk, then mixed a little egg in with it because that's what the recipes online said. It ate pretty good but stayed so skinny then died 8 days later. Now she has drug one up to the porch that looks like it's only a day old! Conservation didn't have andwers for me. The closest rescue doesn't take anything outside their county. So should I just feed this thing strait goat milk or something else? I don't want to just toss it out somewhere hoping the mother will find it. Because I'm sure the dog will find it first
