We recommend the Dogaloo martingale collar because it is an easy-to-use and safe option for your dog. The martingale collar offers a distinct advantage – no matter how hard you pull on it, it does not choke your dog. It only contracts to a certain distance, ensuring that your dog's neck size will not get any smaller. This allows you to adjust the collar to a comfortable width and still benefit from the contraction, preventing your dog from pulling out of the collar without the risk of choking when left alone. While we do not recommend leaving martingale collars on your dogs unattended, exceptions can be made for collars with name tags. There are inherent risks, especially with smaller dogs, where the dog might accidentally choke themselves. Our martingale collars do not feature a snap buckle. Simply place it around your dog's neck and adjust the fit using the adjustable strap. This martingale collar allows you to choose the desired tightness, eliminating concerns about the buckle being a potential weak link. It's important to remember that the buckle is a crucial component, and if it breaks or comes undone, you could lose your dog. Martingale collars are designed to protect your dog, rather than strictly control or train them. Their purpose is to prevent your dog from getting away from you.
