Hi both mine get in to water drinking competitions when one sees the other drink - then they also start drinking. I swear they aren't really thirsty. Then some time can go by and they don't seem to drink much at all from their water bowls - and when in this mood they go elsewhere - puddles etc. I find their favourite around the home seems to be rainwater that collects naturally in a bird bath on the patio....
Cockers can be quite perverse....!!!
