Raustyk, my rott. had to wear one when she had cruciate surgery. The first couple days I had her home (which was the day after surgery) she was ver frustrated with the e-collar but then settled down. Cruciate is a bigger surgery then neutering so luckily she was pretty calm. I just kept her pre-ccupid with lots of chewie toys and kong it seemed to take her mind off the collar. Good luck. Sometimes after a few days of wearing that they learn to leave the sutures alon. Under close supervision you can try to take it off and see how he does. Good luck!
