I brought this lead for my Boerboel puppy, as I had brought another make with string inside, that lasted 2 days! This is brilliant and my dog likes it. It is heavy duty and will hopefully last me a long time. My puppy will grow to be a mininium of 70kg so this lead will do well. It is quite heavy but not enough to make your arm ache! The wide webbing is very strong and the 8 metres is great for the dog to go off and play but still have control. Highly recommend this lead for a large dog or a big puppy, like mine, very strong and very long. I love it!!
