If it was found near Pacific, its my neighbor's dog as they live a block from there near the corner of 4th and Park (cluster of houses at the end of Riverside Park). Their house is the one towards the back of that corner that faces out towards 4th St.
Not sure how to get ahold of them as I'm rarely home. Its a mother and daughter - don't know mom's name but she supposedly work nights at Gallagher's. Daughter's name is Jessica; she's usually home.
I wonder if they even know the dog is gone...they don't seem to take especially great care of their critters. They had some cats that they were feeding, but have now stopped, and they're always begging at my house. Perhaps animal control could pay a visit to them... (?)
