My clydesdales were the most destructive creatures ever. Every morning water was everywhere, all of them would pick the buckets up with their teeth and dump it and we had three buckets in their stalls, dumped everyone, then they would smash the buckets.
I made a bucket bracket out of 6 x6 treated lumber, put one huge bucket in the center and snapped the bucket to the lumber stand. It worked so well I made one for him to eat out of too. I will get a photo today.
I like to dump the old water and give fresh everyday, and I am able to do that with this set up.
