Lupine's No-Pull harness is perfect for use as a training tool, using a pull-and-release action, so that your pull turns the dog from the direction he’s going, towards you. Immediately, as he is redirected, release the pull, so the lead is slack. Made using the same quality webbing and hardware as Lupine's other products, so you know it will hold up. Lupine offers a terrific lifetime guarantee, even if chewed!
 
Here is an introductory video showing how to use this harness.

One size: 16-26"
 
To see if this harness will fit your dog, use a cloth measuring tape to measure your dog's girth just behind the front legs. If you don't have a cloth measuring tape, you can use string or twine and hold it up to a yardstick to see what the length is. Be sure to add 10% to that number for some leeway, and if the final number falls within the size range of 16-26", you should be able to use this harness.  Taking a moment to measure before purchasing will help avoid having to exchange, which just wrecks everyone's day!  : )
