Brand Story I am the brand founder of HHKJ and a dog lover. Many years ago, I adopted an abandoned golden retriever, unfortunately his neck is always allergic, so I tried different types of dog collars for him. Meanwhile, I felt time-consuming and hard when wearing these collars for him, and there were also safety risks. I felt so tired to choose collars then I decided to make a nice collar for my doggie. I was pleasantly surprised that my doggie was very happy when he was wearing the collar I made. It is really an amazing dog collar so I decided to share it with you who love dogs like me. May you and your lovely dog have a great time together with our collar product. Yours Emma Read more Love dogs, we are serious, and you?

Meanwhile,the neoprene padded collar is more breathable and comfortable.
