Reeny's thread about her girl's quarter-sized mating wound made me think it was a good idea to do a public reminder...
For those who breed or plan on breeding, you will most likely deal with a mating wound at some point in time(probably multiple times), so please read this thread!
The large mating wounds you read about(or, God forbid, actually have to deal with yourself!) are not actually wounds caused by males. They're ruptured abscesses. The abscess is caused when a male bites down to hard and the teeth make a small, usually unnoticeable, puncture wound. That wound then gets infected and since it's small it heals over rather quickly, thus leaving no opening for the pus to escape. So it builds up under the surface of the skin until it eventually ruptures. The rupture is the large, open wound that you then can't possible miss. :\
When this happens, depending on the size of the wound, you will most likely end up having to take the glider to the vet
to get them oral antibiotics and possible stitches as well. If this is your first time dealing with a mating wound DO NOT try and do at-home treatment to avoid a vet
visit! If not treated properly the wound can end up getting re-infecting and abscessing/bursting all over again into an even BIGGER wound!
Another thing to keep in mind is that most of the time "mating wounds" are an indication that the female doesn't want to breed. Sometimes it's simply that she's gone into heat too soon after having had joeys or that she's been breeding back to back and needs a break. In which case, you should consider separating the pair during her next heat cycle so she can have a break. If that doesn't work, then neutering the male might be another option. However, neutered males will not always solve the problem since neutered males will continue to breed their females. So be sure to continue watching for mating wounds even after neutering. If they continue to occur then the female will need to be housed with another female and not with any males.
I hope this helps.
