Review on Durable Stainless Steel Pet Training Collar For Medium To Large Dogs - Darkyazi Pinch Collar In Silver (XL-23.62 In×4.0Mm) by Sherman Lancaster

I sent it back, not because it does not work. let me explain. I have a mastiff. i measured her and it should have been snug according to measuring her and the product. however it was past snug. I looked all over the internet as to how this could be. essentially you need about 2 inches more than whatever size you are buying, so for example if her neck is 23 inches, she needs a 25 inch collar. I thought, well ok, i will buy one or two individual prongs then, but this company didn't offer it so i sent the whole thing back. So i think how to fit a dog could be somewhere on the description perhaps, and also the option to buy extra links would have been great. other than that it seemed to be of solid construction and i wish i could have kept it.
