Blue Dog Designs presents its Help 'Em Up Harness, designed for 10- to 30-lb. dogs recovering from surgery, and even for cats. Small, aging dogs often suffer from spine and back issues, and the harness was developed to aid in recovery, the company states. Larger cats—heavier than 10 lb.—that are recovering from surgery also benefit from the harness, which aids in post-surgical physical therapy, according to the manufacturer. It is designed to distribute weight over the large surfaces of the chest and hindquarters.
