I would completely agree with the above. 6 hours is far too long to leave an adult dog let alone a puppy!

Leaving a puppy for any amount of time should be done on a gradual basis. For example, walking into another room and closing the door for a few minutes, until he/she can happily be left for 10 mins or so. Only then should you venture outside and even this should be done in stages.

You really should consider finding day care for your puppy until you can follow the above.
