The No-Knuckling Training sock is a way to help provide training support to dogs that drag their back legs often, and is designed to enhance proprioception (the sense of where the parts of one's body are in relation to each other). It's lightweight and comfortable, with multiple sizes to give your pet the best fit available. It's perfect to help rehabilitate dogs recovering from spinal surgery. It's intended to be used for brief periods, multiple times (2-5 minute walks).
To apply properly, first wrap the training sock around the hock joint on the lower hind leg (see attached sizing picture for more information about where it should be applied), with the adjustable cord on the front of the dog's leg. Then, secure the velcro straps, making sure not to make it tight enough to cut off the circulation or interfere with the mobility of their rear leg. Then, place loop cord under the middle two toes (as shown in the third image under "images" on this page), and tighten the top of the cord so that it is taut.
Sizing Guide: First, measure the length from the top of your dog's paw to the center of their hock joint, as shown in the second image under "images" on this page. The Small fits dogs with a measurement of up to 4 inches (most dogs under 30 lbs), the Medium fits dogs with a measurement between 4 and 6 inches (most dogs between 30 and 60 lbs), and the Large fits dogs with a measurement of more than 6 inches (most dogs over 60 lbs).
