3 week old lab not eating
We got a lab that is about 3 or 4 weeks old yesterday. When we got him home, he threw up dog food. Went last night and bought him ol roy puppy food. Tried to feed him that and a bowl of water. Lapped up the water just fine, wouldn't touch the food. Later on he threw up the water (a few times). Tried again this morning, same thing. Went to the pet store and bought Esbilac a milk replacer for puppies. Can't get him to even attempt to try this. What do I do next?! :confused:
