Is there an age at which the ductus venosus should be closed? With normal liver enzyme levels could a shunt be a cause of vomiting and lethargy?  Is this look like a shunt. 10 Week male Briard woth episodes of lethargy, vomiting and weakness/ataxia.

 Apparently ate a christmas ornament and is vomiting. Lab work WNL at present.
