Maybe the Metacam is kicking in, making him feel more comfortable and that is why he is now wanting out? how long are you confined to barracks - can you take him for a car ride and short, gentle on lead walks..or is it not allowed atm.
for you and Riley
On thurs the vet says no walks for 12 days, so now 10 days , maybe next sun-mon all being well, a street walk,
We could do the car, good idea , might do that,
I have been letting him out the front where its cool, he loves to sit for ages and just observe things, people pass, cars, kids play, dare anyone come near to talk and he gets too excited and barks too much , so I usually only let him out there if its quiet.
