We have a Labrador. She is not quite 2. At night we put her out for a wee and when i do this i always wait and watch until she has wee'd then bring her in. DH has, on a number of occasions, put her out, wandered off, and is not aware if she has wee'd or not. This makes me mad. Should i be cross about this? It can take time and in the winter it is cold when waiting and watching but i think we should know if she has gone or not. Is this an unreasonable request?
