This won't go anywhere. I'm fairly certain that under the law a pet is considered property, so the maximum amount a plaintiff could sue for would be the value of the pet. A purebred greyhound can easily be obtained for under $1000, so the $50k lawsuit is bs.
The libs are trying to go from pets to companions. It won't be long before they are wanting to marry them.
But he’s one of the family! Think of the heartache! < /sarcasm>
