Cops: Neighbor demands $150 to return missing dog

In all 50 states pets are considered property, thus, by
holding this lost property the neighbor could be charged with
possession of stolen property. Yes, I know, the dog wandered
away, but the same would be true if you lost your wallet and
someone refused to return it without you paying them money -
they would, at that point, be in possession of stolen property
&, in some states, could even be charged as the one who
stole the property. If your neighbor had uniquely painted
trash cans and the wind blew them into the street and you
found them. You could not refuse to give them back without
being payed a reward. You are, at the moment you refuse to
give them back, in possession of stolen property and can be
arrested. By adding a monetary sum to be paid in order to
receive the stolen property back the individual can be charged
with extortion.

My advise, get a lawyer, have him contact the neighbor with
explaining of the law & threat to file legal charges, and
if his letter does not work go through with the threat. Have
her arrested when other neighbors are out enjoying the day or
doing lawn work, thus embarrassing her. If she gives the dog
back after being arrested, drop the charges, her embarrassment
will be enough punishment.
