I have a 5 day old puppy who is not eating. What's wrong with him?

Is he still with his mother? If not, why not?

Are you feeding him puppy milk if he's an orphan, or are you trying to make him eat solid food?

No it's a 8 day old and were bottle feeding

DO NOT feed him cow's milk. That may kill him or make him very sick. Call a vet and ask what to feed the puppy. Or check at a pet supply store for canned puppy milk.

Where is his mother?
