I agree with the others. This boy needs to learn that you are in charge. You can do that in several ways eg. obedience classes (I apprecaite this may be awkward for you in your condition) and practising NILF all the time. Do a search on the NILF (Nothing in Life is Free) which basically means that Bear has to do something for everything he wants to do. YOU dictate what that has to be. Here are some examples:

He must sit, wait or lie down, whatever you choose, before being fed, being petted, going for a walk, going through a door, playing, or being given a treat.

Also he must be shown you are the leader by you always going through a door first, you always eat first, only you are allowed on the settee, bed etc.

The privalages of being allowed on furniture can be relaxed if you want but only when he has learnt to respect you and even then only when you allow it.

These are just some ideas. Take more control of Bear yourself. Be firm,fair, patient and consistent and mean it.

He may also be a bit sore from his op, which may make him a bit crabby, but start upping the obedience and NILF NOW.

Good luck.
