I have a 4 year old female Basset that has always been healthy. Just recently her bed, blakents and pillows are always wet. It doesn't smell like urine and we have been very careful of making sure she goes out to relieve herself many times throughout the day. We can't seem to figure out what the liquid is. Seems like clear water and there is so much of it at once but we never actually see her do anything. Anyone have any ideas?
