NEW YORK -- U.S. veterinarians are practicing ever more advanced medicine on the nation's 77 million dogs, 90 million cats and other pets.
In New York City, a German shepherd with a cancerous liver received a $2,000 chemotherapy treatment via a catheter. And a black cat with a lung problem had a CT scan on a half-million-dollar machine offering the fastest 3D imaging available.
Miami veterinarian Dr. Patty Khuly says that for many people, investing in a pet's life improves the quality of their lives.
Advanced medicine perfected on pets sometimes leads to procedures for humans. A doctor at the University of Wisconsin-Madison School of Veterinary Medicine says a surgical technique to repair torn knee ligaments in dogs was so successful, it's now used on NFL players.
