Mountain dog have been fantastic. Very quick delivery. I ordered quite a bit over a couple of deliveries and one item didn’t fit so I sent it back and the received a prompt refund. The Ruffwear leads, harnesses and collars I ordered are very good quality and I am so pleased with them. The Crag lead is comfortable to hold and practical. I have my dogs on the shortest option to walk along the path to the field then I can extend it easily to double the length. The clip is very secure and although it takes a few seconds longer to put on and off it is safe and secure and I don’t worry about it coming undone when the dogs are playfighting. Very happy with my purchase. 5 stars!
