Query: It's a miracle!

The Easy Walk harness is the best invention. It's like a miracle for my 50 lb blk lab who would pull so hard and choke himself the entire walk. I hesitated to use the gentle leaders - with a black dog, sometimes people are afraid of this love bug and the leader looked too much like a muzzle. I'm so glad I found this instead. Walks are so relaxed and enjoyable now. It took a couple of tries to fit him but I found a helpful youtube video online. I paid a lot more for this at petco but had to return the large for a medium size because he's petite. Highly recommend!
