neutering of scottie

Question
I watch my neighbors scotties during the day and some eves & am wondering exactly what the vet did to neuter him yesterday.  He did use a laser so there is no incision or bandages so i'm very curious about how it is done. We picked him up at 6PM after his 8AM sign in time, and he was great.  He came home and ate and went out(on leash) to urinate and poop and acted as if nothing had happened.  In fact, the biggest ptoblem is keeping him from jumping on bed and furniture & "roughhousing" with his 2 yr old "sister", Lucy,(Ricky is 10 mos).  The vet said to watch for swelling & keep him quiet as possible!  So, hope you can tell me exactly how they accomplish laser neutering.
Thank you so much,
Sharon

Wow what an interesting topic! Well from the sounds of it(I did a search)it sounds like the opening and the 'parts' are removed by laser,thus less blood and faster recovery time

Hope this helps-this is one of the most interesting qustions i've had yet
