My Indian Spitz doesn't eat food by itself. Six months before it had a leg injury because of the

injection given by a vet and from that time onwards it stopped eating by itself. My mother started feeding it like as we feed a human childin childhood. Now the leg injury has cured BT still it doesn't eat by itself. My dog waits for mother to feed her by mom hand.My dog eat nothing by herself except the chew sticks And now I want to make my dog eat by herself. Please guide me how to do.
