Thanks all! And ya, most of the time, he doesn't know he's sick
He sleeps a lot, and when he plays he's very weak and clumsy, but it doesn't stop him!
He had SUCH a wonderful day today!! He was up for a good 60 % of the day, normally he's up and moving around at feeding time and the occasional energy burst, but today was great! He was barking and howling a lot, biting me, pouncing on Thorin... he was just such a puppy
It really made my day. I think this is the most active he's been for a prolonged period since we've had him
