This is Just an FYI kind of message:
NEVER spay while the girls are in season because of the increased blood flow to the uterus. The increased blow flow can cause complications and cause them to bleed much more than they normally would which of, course, if they can't get the
bleeding to stop would cause the death of the animal. It is a very risky surgery to do a spay while a bitch is in season. Actually, since she is already in season, they should wait about 2 mos. This will give the hormones time to go back to normal and to make sure that all the blood flow has also gone back to normal.
