So I think this is going to sound really wierd, but Molly has one really short nail on each of her front paws. It is the middle nail and I'm sure it's because of the walks we take her on (We walk a couple miles a day on mostly on asphalt). It doesn't bleed, but she spends a lot of time licking it. The other nails are short as well, but not like these two.
Any ideas on how to stop it from becoming so short?
