Gee thanks for the suggestion. I never thought about the water bottle. it certainly is worth a try. I bought him a collar with a bell today thinking if it alerts birds it may alert her that he is about to jump her. Not sure that it will help but at this point anything is worth a try. Not that it is a constant problem. Seems to happen more when we are not here. We know because when we come hair there is her hair all over the place. Again, thanks for the suggestion.
