Missing Frenchton (Palmer Lake)

Missing dog. Small black and white boston/frenchie mix. Her older brother passed away today and when I took him to get cremated she got out of the yard through a hole under the fence. Her name is Momo and is 9 yrs old but doesn't act like it. No collar but she does have a microchip. I live off Lake Dr SW in Palmer Lake. Please contact me if you have seen her.
