Initially, when we bought this product in November, we used it every other week to assist in basic maintenance for the rough surfaces my two GSDs often encounter. This week, we had 12+ inches of snow which was followed by -20 degree temperatures with windchill reaching around -50. Both dogs have been suffering even going out to go potty briefly. (There is no way that they would wear boots or socks – they simply stop moving when I put them on.) Their paws were cracked and dry and it was apparent that they were suffering. The past 2 days I have been applying a light layer of this magical stuff and have seen a major improvement!! We are so thankful for this item. Will continue to use it and spread the word to other dog owners!! Thank you!!
