We have two jack russell dogs and one is marking and urinating in their room. We also are dog sitting a little poodle (girl) who has also been spayed but one of our dogs is smelling of her bottom. Do girl dogs still go through a cycle after spaying? Would this be the cause of the male dog doing this as it started when I put her in the room with them while I had to be away from the house for a few hours and she urinated in the room?
