Not dealt with this before, as I've only had dogs not bitches. She is 13 months old, has been bleeding for a couple of weeks-ish maybe a bit longer. That is subsiding now, she still has a discharge but it is less strongly red. she possibly looks less swollen up than she did. She is also trying to mount me! How long does it all last? We are being careful on walks and it will be nice to let her run free again without having to wait to check what the status is of any dog that may be nearby. Usually walk her on the beach so it is easy to spot dogs in the distance. We are going to have her spayed (am dreading it though) but our vet wants to wait until after this season, and when she is fully grown, so a few months time. How traumatic is spaying?
