Michaela -- I agree how can dewclaws be worn down <G> maybe from excessive holding onto chew bones NOT even if galloping on road that dewclaw wouldn't come into play much touching the ground. I can see how it may help with landing while jumping or turning but just don't see it happening with most dogs that have the front dew claw (sorry Mary-Ann) your explanation for reasons to keep front dewclaw was great.
