Ok, so I did a +6 and he was up to 11, then at PMPS he was 13....and he perked up a bit. We put our heads together and turns out when I made a crockpot of pulled pork yesterday my husband took the skin and made crackling....and the bit was too fatty for him? He gave to Tucker just before bed. We think the super thick, fatty pork made him sick to his stomach. As the day has gone on he seems more and more himself. Fingers crossed that's all it was, at the moment he ate 2 handfuls of shredded chicken for tea and was much more bright.
