Lost blue dog collar with a small silver tag engraved 'Buddy' and owner's phone number near the large oak tree at the park in Green Bay.

I lost my dog's collar while walking him at the park near Green Bay. The collar is blue with a small silver tag that has his name, 'Buddy', and my phone number. I last saw it by the large oak tree along the walking path. Please let me know if you've found it.
