I was glad to find this question as I'm afraid I will soon have a similar issue. My cocker, 2 years old, has been lucky enough to have me home all of his young life. Now, due to a change in my husband's work status, I'm starting to look for work myself. No idea at this point how many hours a day he will need to be left alone, but I am very worried what the change will do to him. Apart from the issue of having to "hold it" until someone comes home, how can I prepare him for the loneliness he is bound to feel?
