Have you checked to see if all her teeth are through? Sometimes they are not really fully weaned when they leave the mom that soon. But since she did eat well for a couple of days and then stopped it is concerning. Is there anyway she could have been exposed to an area where other dogs have been? There is a particular parasite that can cause a puppy to lose all appetite.
Maybe try getting some Puppy Replacement Milk at your vet's or local pet store and mix it with your ground dog food. It may taste better to her than the food with water on it. Don't put regular cow's milk in the food through. Goats milk is good, too. |
