What a sweet face!

First I'd check her for fleas/ticks, (is her fur badly matted underneath?) maybe give her a bath and a flea collar, quick trip to the vet if you can ...

What a face! Bet she's half that size wet ...

I'd of course check with all the local shelters/vets/animal control, see if anyone is missing a chow pup ... just in case she belongs to someone but got loose/lost ...

What a sweet face!
