My name is Nishioka and I bought this multipurpose harness of Medium size from you. I got it successfully in 2 weeks. I have tried it at once during a walk. It fits nice. Many thanks. Our Golden Retriever Taiou is already 3 years old, but he still pulls on the leash. We have tried everything, but hadn't found anything good. We had put on him this harness and I thought while walking: "Really? He had been pulling hard before and now - not". The harness is rather durable. It matches perfectly. I like it very much. The only thing I want to ask you, please, make more sizes for neck adjustment. I will be grateful if you improve this. Thank you!
