He just won't drink from any of his bowls. I keep them clean and change the water daily. I've swapped the stainless steel ones for plastic, swapped the plastic for a pottery bowl but nope. He eats from exactly the same type of bowl with no problem. I'm now giving him ice cubes to keep him hydrated. Totally different story when we go on a walk and he ses a puddle. He'll drink those in a heartbeat.
So I don't know what else to do! Any advice please?
