Think Smart Long Line


Think Smart, Lead With Kindness! For every Long Line purchased, a biothane leash will be donated to the Humane Society of Boulder Valley!

Looking to give your dog freedom of movement, but want to have the security of a leash? Long lines give your dog the ability to sniff, explore, and stretch their legs while still safely being held by their human adventure companion. 

Biothane long lines are waterproof and are easily cleaned by wiping them down. Long lines are great for those working on recall skills, or those wanting to explore with safety in mind. 

All long lines have an auto-locking carabiner for a clasp.

Available in 20' and 30' lengths and the following widths:

1/2" (best for dogs 25 lbs and under)

If you would like a custom length, please send me an email at hello@thinksmartdog.com
