The doctor pushed the blood work and it's back and it's completely normal. We were basically told the only way we can possibly find out is post-mortem. We've made the heart wrenching decision to put him down, it's clear he's becoming miserable and he's rapidly losing mobility and weight. The only question is when... Emily is gone and doesn't know we got the results back. We don't want to pick her up then drive over right afterwards to put him down. We're all very upset. We still haven't even had a service for Nikki.
