I have to keep the water for the dogs and Bruce empty because Aubrey will play in the water. So I fill it for them several times a day and only leave water in it when Aubrey has gone to bed for the night. This is a huge pet bowl. That several times a day isn't always enough for Molly. She lets me know she wants water by flipping this huge water dish around the room with her foot or nose. It's quite successfl because you can't stand the racket it makes long enough to ignore her. lol She'll also do this if she thinks her supper is late. Bruce the cat came to us with a similar habit. If the dish is empty he starts pawing it. If we don't hear him......he eventually gives up, curls up inside the water dish, and goes to sleep. Yes, my dogs and cat drink out of the same bowl. I'm guessing by sleeping in it Bruce hopes to get first dibs the next time it's filled. lol Now Betsy, she's the really smart one. She lets Molly and Bruce do all the work for her, she just makes sure she's front and center when it pays off. by the way Molly and Betsy have been getting along fine of late. I think Molly is feeling her age.....and then some and was cranky. They're separated to eat, and in certain situations where I know it triggers excited behavior from Betsy.......they're gated apart until Betsy has time to calm down. So far it's working.
