I am wondering how to get my 5 week old puppy to eat. She won't eat and she has a splint on her right back paw

Why does she have a splint on her right back paw ? Five week old puppy is pretty vulnerable, poohbear. How did you come by having a pup that young? If you tell us more we will be able to answer you better.

Yes we definitely need more details. Like what are you trying to feed her, why she isn't nursing from mom, and what has your vet suggested, and what if any meds is she on? Has she been treated for worms or fleas yet?
