Should we allow our 4 month old GSD puppy access to water while he’s crated during the day while we are gone?

Hi,

We got our German Shepherd puppy 2 weeks ago while my girlfriend was on break from school vacation. He has learned to go to the bathroom outside, but has an occasional accident. The question I have is that he will be left in the crate from 8 am to 3 pm Monday to Friday. Should he have access to water while we are not home during this period of time? We have heard several different opinions, but it seems a little cruel to leave him without water for that period of time. Obviously, he is 4 months old and has to pee quite frequently. I notice if he drinks a couple bowls of water at one time he has to go once an hour for a few hours. What is your recommendation on the amount of water or lack thereof to give him during this time period?

Ps. I am asking you because of your excellent answers on your webpage.

Thank You,
Mike
