4 week old puppy questions?!?

4 weeks is plenty old enough to begin eating a "Gruel" Made of moist puppy food and canned CHOPPED BEEF Pedigree canned dog food all smashed together. Offer water or Esbilac milk replacer in a bowl. He is whining because he is a baby. Equivalent to an infants cry. There's always a pup in every litter that is nosier then all the others. Dawn should help with fleas. Make sure the bedding is washed to not re-infect the pups and they are thoroughly dry and free from drafts.
