Information from the shelter's facebook: Nick was picked up as a neglect case and once we had won custody of him he was adopted into the family that owned Shadow where he lived happily for 2 years. Then several months ago both he and Shadow were turned into the shelter. Both dogs are about 5 years old.
I don't know why he's not listed on their petfinder but the shelter is doing a whole bunch of updates and they're missing a ton of dogs on PF, so that could be why. Here is the link to his album on FB: Click Here
