Tuff Foot..Misty used to shred her paws every single summer, on every walk, every run etc.. droved me nuts, I tried a million things. she HATES the Tuff foot, I think it stings her a bit when I put it on, but I only had to do it a few times and it toughened up her pads, I dont even bother with the maitence applications and her feet have not shredded since. I lent it to a friend who was havuing the same issue with her dog, she used it like twice and hasnt had a problem since.
