kaspera79:The answer is simple from a dogs mind. Toilet water is colder, often times fresher, and may taste better because of the container. Also, animals don't really rationalize the source of their water.. Are your regular dog bowls plastic, ceramic, or steel. They may leave a taste preferred less. Yeah, I know less than toilet. Try washing the drinking bowl and changing the water a few times a day the water may be stale. (not you zero, but anyone who has this problem)... And always put the lid down on the toilet.. I sound like my wife now. If the toilet has been cleaned recently the chemicals can still be in the bowel, and if your dog is in the habit of drinking from a toilet, that could have a bad result.
