I had a water bottle but my dog never "got" it. At one point he chewed it, so I ended up throwing it away.
Now I have a silicone collapsible bowl that attaches to the side of the crate. He loves it and it's his preferred water bowl for some reason. Weirdo.
Edit: I think this is the one we have - https://www.amazon.com/Dexas-Popware-Pivot-Collapsible-Kennel/dp/B007A4VD1Y
