Does anyone use this or have any recommendations? Our puppy is 17 weeks old now, when she came to us her paw pads were like velvet as she hadn't been walking outside. Now they are starting to feel "worn in" just wondered if there is anything worth buying to keep them soft or should I just leave her be? It's not bothering her at all, it's just me noticing it and to me it's like us having dry, rough feet lol but I guess it's normal for dogs?
