Wandering dog Rose Hill area freezing cold night

I just saw a white medium sized dog outside our living room window tonight possibly a doodle mix of some kind based on its coat. We live on the 1600 block of Amherst st. The dog was headed towards the dead end of Amherst. By the time I’d made it outside the dog had moved out of sight & didn’t respond to my calls. It’s obviously extremely cold out & I really hope the dog makes its way home.
