I posted a thread concering changing Samson's food from Puppy Chow to Nutro Lamb and Rice. After two days mixing the puppy chow and nutro, and him refusing to eat the lamb and rice. I purchased canned lamb and rice and started mixing it with the dry Nutro lamb and rice. Late tonight he finally ate all of the dry and canned. Tomorrow may be a different story, as he changes from day to day.
