A family in Bristol has decided to take an unusual approach to getting their lost dog back -by spraying their urine around their neighborhood. An animal behaviorist gave them the idea.
Of course, my first suggestion might be putting up lost dog posters and checking the local shelter, but I'm no animal behavior expert.

of course this needs to be done before the pet goes missing..
good luck!
