Has anyone seen this "training collar" before? Scruffy Guider Dog Training Collar It's supposed to be a good correction collar, that doesn't hurt the dog's neck. It's "Limited choke." What caught my eye about it was that it has a handle of sorts, and how it spreads the pressure evenly over the dog's neck. I highly doubt that it works well as a "correction" collar, and I doubt that it's impossible to harm the dog's windpipe. It looks uncomfortable, above anything else. I have no idea how it would inhibit pulling on the leash. Just curious. Would any of you try that on your dog?
