I have talked to my vet about this in the past, because when Cisco gets too excited or scared he will express his glands. Yes, it can be stinky! The vet told me that he didn't belive in expressing glands without having a real medical issue. He said that this is normal for dogs. I have never seen Cisco scoot, but for sure he has expressed himself. So I just don't worry about it. I do think regular bathing can help.
