I bought a Pomeranian puppy from a pet store last year. She was sick with kennel cough and loaded with fleas. I have since spent hundreds in vet bills, not only for her, but also for my other dogs, who caught her kennel cough. The pet store's guarantee says I have a right to be reimbursed for the puppy's vet bills (though they haven't yet paid). But can I also sue them for the vet bills for my other dogs?
