The BIKO Progressive Resistance (PR) Bands is an elastic resistance band that runs from the dorsal midline D ring of a standard Roman harness to the tarsal area of the dog’s hind limbs, just below the hock. The bands come in a color-coded system of progressive resistance – yellow (light), red (medium), and green (strong).
 
The bands stretch slightly as the dog walks and assists the forward movement of the feet, also protecting and preventing the feet from knuckling under.  This is very helpful for dogs with poor muscle strength, or nerve disorders that prevent proper foot placement.  As the right hind limb moves forward, the resistance that develops in the left Biko PR Band prevents the left foot from slipping sideways or backwards; the process is repeated on the other side as the dog walks.
 
With more stability and control, dogs with hind limb weakness, lack of coordination, or decreased proprioception can get much more benefit out of exercise – whether walking at home or exercising at a rehab facility.
