Our greyhound came into season a few days ago. The Devil one is neutered and we are doing short lead walks at quieter walking times, so it's not really a problem. She is bleeding all over my house. I don't remember my mum's lab bleeding that much, but I've been told it's normal and my house is fairly wipe clean, bar one carpet, which is dark red anyway.
The problem is since it started she is weeing in the bedroom every night, which is the only carpetted room in the house 
. It only started when her season started, which makes me think it's connected? Will it stop when her season ends or do I need to start setting my alarm at ungodly hours to retrain her?
