I think JP's face in that pic speaks for itself. He's adapted to his new situation amazingly. He still enjoys chasing the ball, swimming, and hunting like he did before just in shorter spurts and with less rules and more table scraps.
He gets around well but it does take more effort now so he has only hunted short 20-30 min runs at first light when it's still cool out. JP hasn't got a bird yet this year, I know he will, but if I could project some human emotions on him I believe he realizes his situation and is happy just to be along for the ride.
Unfortunately he is not cancer free and I'm not pursuing anymore treatment. Not sure how long he'll be around but every day with him is a blessing and any walk behind him with a gun in hand is just icing on the cake.
