Los Angeles (AP) — More veterinarians are using wheelchairs, orthotics and prosthetics to improve the lives of dogs that have lost limbs to deformity, infection or accident, experts say. The move is driven by persistent pet owners who embrace their animals as family and aren’t deterred by the cost and commitment of outfitting disabled dogs with the devices. At the same time, there have been great strides in technology to keep up with U.S. soldiers returning wounded from war, and veterinarians have adapted the materials and know-how for the rising demand from clients.
