Re: What do u have Watering bowl or bucket for winter?
you can try use a water heater, ones made for fish tank, but problem I can see with one of those heater is the dog can easily pull it out and chew on it. Most of them are glass and they are all electric, so if you got a chewer, then I wouldn't use it. If your dogs are calm and you know for fact they won't pull it out then I think it'll work.
