Hey! sorry for the late response, the way curezone is setup is a little confusing. It's a shame that this thread didn't get the attention it deserved! I think this information can be very valuable to a lot of us here. The reason it's not known better is for the very reason it never been heard before. People make the assumption that only dogs or other mammals have anal glands but this is not the case at all.
I'll try to get a hold of the doctors name and phone number but right now i'm having difficulty in doing so. I think the doctors responsible are long gone im afraid :( I don't know if any other doctor picked up on this or not. Its a very tricky subject. If you want to know more PM and i would be glad to talk. take care
