I don't think it's a big deal to leave your dog alone for the day (obviously, in a safe penned off area!)
I know it's harder (and riskier) to leave a "puppy", but look at how risky it was to TAKE him! I know everyone always posts that "if my dog can't go, I won't go", and all the other associated problems with taking your dog places where people don't understand or respect your wishes concerning them, etc.
I just think it's SO much better and less stressful for the dog to LEAVE THEM AT HOME in their familiar surroundings! They may whine when you leave, or miss you a bit, but 99% of animals will just sleep the day away while you're gone. Then ten minutes after you're home, they've forgotten you were ever gone!
