If u dont mind i being frank, if you use it to wipe away the tear stain, then the fur will become harsh cause if it able to removes stain, meaning it able to remove the protection layour, hence the coat will dry up. The next time the stain will be even harder to be remove. Hope it doesnt cause any discomfort to u, i'm just suggesting based on my personal experience, you guys are free to choose what product you want to use though.
