K-9 Orthotics & Prosthetics President Dr. Jeff Collins, who has a prosthetic limb himself, operates on border collie Driftwood to prepare the pup to receive two prosthetics for his back legs. Animals such as Driftwood that have met with misfortune, whether from a birth defect, accident, disease or even human cruelty, are now getting a second chance at life due to human intervention and technological advances.
