I bought this collar and the matching leash for my 3 year old, 50 kg, rottweiler. First of all I was surprised by how fast I recieved my order, since I live in Norway. Secondly, the quality of the collar and leash was extraordinary, especially given the nice price. But the most surprising was how good my dog looked wearing the collar! Usually he only wears loose, metal collars, because his big rottie neck doesn't look espesially good in tight, leather collars. But this one looks amazing on him! And it provides great control for me and comfort for him. I can absolutely recommend this collar to other owners of big dogs! Thank you very much for suppling solid, quality equipment!
