Hello All.
I wanted to say I hope your boy will be ok,I was a Vet tech/surgical asst for 17 years and mostly the only problems I saw
were male dog scrotums swelling and then having to be ablated or removing the the scrotal sac.
Most Hospitals will use Ice packs on the surgical area for a while when the dog is still asleep and helps with swelling of the incesion site and if the doctor uses a subcuticular closure which is to say that the sutures in the skin will be just below the skin the pet won't have sutures to stick them and that of course brings attention to the area.
As to neutering tom cats,leaving the incesion area open is not a new thing,as I said i was in the field for 17 years and that is the only way that was done. It seems that cats don't mess with it when it is done that way.
They do the same thing to stallions out in the field,they sedate the horse and then cut the scrotum and use the emasculators to crush the cords and then cut them out and they do not suture the incesion at all and the same thing happens with calves.
I know it sounds brutal but they are sedated and don't really know what is going on and I can attest to this as I also assisted with farm calls and saw the above many times .
May I make a suggestion? those of you that are planning on having your pet spayed or neutered ask your vet to use a cosmetic closure and that means that the absorbing suture will be just below the skin and dosen't seem to cause the pet any discomfort and they usually leave the area alone. That is for Dogs male and female, the male dog can also have a cosmetic closure with his procedure.
Hope as up front as the above was that it helps you to make a better educated decision when you do spay or neuter and talking to your Vet about can they do the closure that way. It doesn't hurt to ask.
By the way female cats can also have a cosmetic closure and they usually leave the area alone since there isn't any nylon suture to poke at their skin when they either lay down or sit down.
It also sounds like he may have a tracking abcess that may have opened in a hole from his licking and introducing bacteria into the wound or surgical area.
I again wish you well and that your boy recovers quickly.
