Oh just look at that beautiful smiley face!! He's such a happy little chappie! :3 he doesn't look 11 at all either. I've never met a Tibetan spaniel but I do hear they are a bit standoffish, you must be very special to him indeed
My Nanny's little cocker spaniel also had an undescended testicle, he just got both that one and the other one snipped a few weeks ago. I thought my Nanny was pushing it a bit leaving it until now when he's over a year, poor Simba having to put up with that for so long!
I'm not surprised there's been such a change in him, he must be so relieved
