Hello Everyone!
Yes, we also have a clean water dish problem. We have 3 Newfies, two 2 year old siblings and one 9 month old half brother. Of course the two boys are pigs and leave their slime & debris in the water dish for their sister! If she doesn't get the first drink from the clean bowl, she will bark until someone changes the water for her! She also has a hidden, well it used to be hidden until puppy boy pig found it, a fresh, always clean water dish upstairs in the bathroom. She hates slime and she lets us know when the boys leave a mess. We recently found out that their Mom does the same thing because the boys in that house also leave slime in the dish and she won't drink from it either. Like Mom, like daughter! Our boys are big pigs but, we love them just the same. The best is when the boys take a drink and if you don't have a drool towel nearby and they get an unsuspecting person passing by, that lucky person gets a wet, full of drool lap! Summer is even better with shorts on! Not sure why we shower somedays!
