I am looking for the owner of a lost dog

On December 13 (Wednesday) I protected my hesitation dog near Mr. Motomachi Dog Tail (DOG TAIL). The color is black and brown and the hair is long and fluffy, the size is medium size.
Please see the picture below. Collars and clothes are also attached, and it seems to be a domestic dog because it is accustomed to humans.
If you have any information, please contact the Town Hall Resident Affairs Division (Mr. Sato).
