You need to keep him eating whatever he will eat. Try to feed him severaL small meals. Give him a pea size amount of nutrical every 3 hrs. If he ever gets down as you say and the nutrical doesnt bring him out of it youve got to get him to the vet right away so they can get an IV in him. You might want to have your vet bile acid test him because pups with liver problems also have trouble maintaining their sugar levels |
