Harley has taken to giving himself footbaths in his water bowl. obviously this is making his water very poopy and unsuitable to drink. his water bowl is a small little heavy ceremic crock. he likes to put his front feet in, stand there for a minute and then continue walking through it. any ideas of how to make him stop doing this? i've been making my boyfriend change his water in the wee hours of the morning for the past few nights but we need a better solution!! help!!
