Last month, Zachary and his girlfriend adopted an adorable dog, Sophie, from a rescue organization. She had been transported across several states from a shelter to her new home, but arrived extremely ill. Her new family rushed her to the veterinarian, where she got badly needed but expensive treatment. The vet claims that Sophie should never have traveled in her condition, and would have showed symptoms long before the transport left. The rescue claims that she wasn't sick before departure. So who should pay this vet bill?
