K9 Sport Sack Plus 2 Small Backpack Dog Carrier - Comfortable Ride

Our review of the K9 Sport Sack Plus 2 Small finds it best suited for owners who want a durable, comfortable way to bring a small dog along on walks, hikes, or bike rides. The single biggest reason to buy is its reinforced comfort design: thick, padded shoulder straps and a padded back panel let the carrier support more weight and remain comfortable over longer outings while keeping the dog secure and ventilated. It is a practical, well-built option for dogs in the 13-16' length range who need a close, supported ride.

Key Features

• Backpack dog carrier: The Plus 2 is designed as a backpack-style carrier so owners can carry their dog hands-free on walks or rides.
• Padded comfort: Thick, padded shoulder straps and a padded back panel distribute weight and reduce strain for longer, more strenuous adventures.
• Size guidance: The Small fits dogs 13-16' from collar to base of tail with a girth up to 27', helping buyers choose the right fit for breeds like Jack Russell Terrier and Pomeranian.
• Multi-functional storage: A removable storage pack plus two full-size water bottle holders provide space for gear, treats, and hydration on the go.
• Ventilation and fit: Patented taper-fit design and mesh panels support and stabilize the dog while allowing cooling airflow for comfort during the ride.
• Durable construction: Heavy-duty 600 lb. test webbing, triple-stitched seams, and bar tacks on high wear areas are built to last through frequent use.

Who It's For

This carrier is ideal for dog owners who want to bring a small, active dog on longer walks, hikes, or bike rides while keeping hands free and distributing weight comfortably across the back and shoulders. It works well for owners of small breeds around 13-16' long and with a girth up to 27', such as Jack Russell Terrier, mini French bulldog, and Pomeranian.

Owners of larger dogs or pets that do not enjoy being restrained in an upright position should look for a larger or different style of carrier. Also, if a pet needs complete freedom of movement instead of upper arm openings, a different travel solution would be more suitable.
