I noticed that my Metoo has quite a bit dead skins on her pawpads, both front paws and feet, but front ones are better. Possibly it's been a while but I didn't notice. I want to know if it is a concern? Because my Meatball doesn't have those dead skin on her pawpads at all. Also how can I make it better? I would like to apply some hand lotion on Metoo's pawpads, but afraid that she will ingest them when grooming her paws.
