Big Old Pup’s Revolutionary 5-in-1 Hands-Free Dog Leash System Will Transform the Pet Walking Experience

Innovative Leash System Supports Five Functionalities Dog Owners Rely on Every Day

(PRUnderground) August 18th, 2025

Big Old Pup, a pioneering pet solutions company dedicated to solving real pet problems, today announced the launch of its breakthrough 5-in-1 Hands-Free Leash and Seat Belt System. The revolutionary product combines five essential functionalities into one ergonomically designed solution: hands-free walking, in-car doggie seat belt, reflective safety features, mobility hoist support, and integrated storage.

Founded by lifelong dog enthusiast and product innovation expert Corey Lieblein, Big Old Pup was born from a profound moment of recognition that the pet industry lacked truly utility-based solutions engineered to address genuine challenges faced by dog owners.

“After years of caring for dogs, I witnessed firsthand the gap between what pet owners actually need and what’s available in the market,” said Corey Lieblein, Founder and CEO of Big Old Pup. “Our 5-in-1 Leash System isn’t just another pet accessory; it’s a high quality, thoughtfully engineered solution that transforms the entire walking experience while addressing critical safety and mobility concerns.”

The new Big Old Pup 5-in-1 Leash System features: 

  • Hands-Free Walking Technology: An ergonomic, padded cross-body design that eliminates strain on shoulders, wrists, and fingers by utilizing the body’s core strength for natural dog guidance. The system also includes a leash extender for added versatility and an additional support strap.
  • Instant Car Safety Solution: The leash transforms in seconds into a secure in-car seatbelt safety system with an integrated universal seat belt buckle, addressing the thousands of car accidents and pet injuries caused annually by dogs improperly secured in vehicles.
  • High-Visibility Night Safety: Ultra-reflective fabric used on the cross-body design and woven throughout the leash enhances visibility during night walks, reflecting light from vehicles and streetlights to protect both pets and owners.
  • Mobility Hoist Support: A built-in support system designed to assist older dogs, those recovering from injury, or nervous pets on stairs and challenging terrain, allowing owners to provide gentle lifting assistance.
  • Integrated Storage Pouch: A sleek, low-profile compartment positioned for quick access to essentials like phones, keys, credit cards, and waste bags completes the hands-free experience.

The inspiration for Big Old Pup manifested itself during a Spring 2024 moment in New York City when Lieblein witnessed an elderly gentleman struggling to lift his small dog. This experience, combined with Lieblein’s 25+ years of expertise in consumer product design, manufacturing, and quality control, sparked the realization that the pet industry needed genuine innovation focused on utility rather than aesthetics.

“Every feature in our 5-in-1 system addresses a real challenge I’ve experienced or witnessed during decades of dog ownership,” Lieblein explained. “From the physical strain of traditional leashes to the safety concerns of night walking and car travel, we’ve engineered high quality, durable solutions that make life better for both dogs and their humans.”

The Big Old Pup 5-in-1 Hands-Free Leash and Seat Belt System is available for purchase through the company’s Shopify website at bigoldpup.com, Amazon, and TikTok Shop.
