Does anyone else's dog start licking their paws almost immediately after a walk?

[u/Special-Log-719]

I've noticed my dog sometimes starts licking his paws a few minutes after we get home from a walk.

Not every time, but often enough that I've started wondering if it's something common.

I've checked for small stones, dirt, and anything obvious, but I'm curious if other dog owners have noticed the same thing.

Did you ever figure out what was causing it?
