Perviously, we have walked our dogs on a collar and lead or a head collar but our rescue Golden Retriever had been used to a harness at his foster home so we chose this harness and we are delighted with it. It is light but strong with good construction and attractive too. The initial fitting took a few minutes to get each of the three adjustable straps to be snug without being tight. Our dog is perfectly comfortable and walks brilliantly with this harness. We combine it with the matching training lead, worn over the shoulder, to give a "hands free" walk. Honestly, exercising the dog has never been easier.
