Have had my 9 week old puppy for 2 days now, me and my wife are after some advice on leaving our puppy at home whilst at work, I work 15 hours a day 3 - 4 times a week and my wife works 4 hours a day 4 times a week and one day working 7 hours, we are currently leaving him in an open crate in the hall way which he has access to a little food and some water and lots of his toys, also he had the radio on, he seems to be ok with the routine but we was hoping maybe we could be doing something else ?
