Choke Chain, German Type (Oval Type) Chain Collar Made of Stainless Steel For Small to Medium Dogs 2.5 x 400mm A: Head Circumference (Size needed for choke chains, choke collars, etc.) ◆ This is a training choke chain that helps prevent pulling during walks. Made of stainless steel, it is highly durable. ★ Example) If the actual neck circumference is 29cm, it would be 34cm (29cm + 5cm), so a 35cm size choke chain is appropriate. At this time, be sure to also measure the head circumference and confirm that the choke size is within 35cm before purchasing. For dog breeds with large heads, such as Chihuahuas, French Bulldogs, and Boxers, if you only choose based on neck circumference, the choke chain may not pass through the head, so please be careful. ◆ 20 x 320mm is also available♪ #Training #Training #PullingHabit #Choke #Collar #Necklace #Chain #ChokeChain
