Thank you Mary T for taking a found dog in today, and thank you Beatris for scanning him! The phone number for the registered owner wasn't current, so Mary messaged microchip hunters for help.
I was able to get a hold of the grandparents of the registered owner, who let her know to call me. She let me know that she had rehomed "Moose" a few years ago, and that she would try to get a current number for me. Thankfully she did! They were missing him, and were happy to know he was found and was safe. "When he joined our family in 2018 we named Him Leo, thank you for your help, my son and daughter just left to pick him up."
Mary said "The best was seeing Leo’s reaction when he heard & saw them!"
Thanks again to Mary and Beatris for their help getting Leo home, you made a dog and his family very happy!
Leo's family will be transferring ownership on the microchip too!
