17.5 Long Line is worth considering if best simple mid-length line is your priority in long-line dog leashes. Check fit, current price, and retailer availability before buying.
Skip it if no alternate length or width on this product page is a dealbreaker, or if your pet needs a different fit, size range, or retailer return policy.
Compare related options, then check current details with the retailer.
Pupford
Pupford is the least expensive retained option and still provides a handle, solid clasp, 30 ft length, two dog-size variants, and 24 product reviews. Nylon is economical and familiar, but it is less weatherproof and less wipe-clean than the coated-webbing leaders.
Mendota Pet
Mendota is the strongest non-coated-webbing alternative in the ranking. The line uses the brand's multi-filament polypropylene rope with UV coating and comes in six trainer configurations from 20 to 50 ft, including a 1/2 in Pro Trainer and high-visibility Super Cord options.
PRÊT-À-PUPPY
PRÊT-À-PUPPY offers a wider 5/8 in line in five useful lengths and includes a coordinating storage loop. It is handcrafted in Mississauga and ships worldwide, but the US-localized starting price is higher than several larger evidence-base competitors and only two product reviews were available.
Viper by Dogline
This fixed 20 ft Viper line stands out for its Herm Sprenger stainless-steel hook and three width choices. Dogline publishes a 570 lb breaking-strength claim for the hook, not the complete leash, and offers separate 10, 15, and 33 ft versions for handlers who need another length.
Trailblazing Tails
Trailblazing Tails is the only retained option with three clearly published webbing widths tied to overlapping dog-weight guidance. It works as a handle-free drag line or extension by default and can become a conventional long leash by adding the brand's Handle Option 3.
Train Right! by Coastal Pet
Train Right! is the only cotton-web option retained, giving handlers a familiar soft material and a swivel bolt snap across 6-30 ft official configurations. The 20 ft version was currently offered by Petsense for $24.99, but cotton is less practical than coated webbing in rain, mud, or repeated wet trail use.
