With the Kombi Martingale Collar there is no choking effect as with traditional choke chains.On the lead there is still the jingle sound of the chain when the attention of the dog is required for control, pulling or any other behavioural problem.The Kombi Martingale Collars are both fully adjustable to the quoted sizes.The collars are converted into a non-choke standard type collar when the lead is clipped on at this point. The Snap on Kombi Martingale Collar has a unique high quality snap clip. This allows for correct adjustment with any particular puppies with thin necks. Further this allows for easy removal of the collar as and when required even in an emergency. Fittings, fabric and snap buckles are of the highest quality.
