A rather cheeky design if you own 'that dog'! I have been told that this is an affectionate nickname for a Dog de Bordeaux, hence the half check chains available in 40mm. These are available in the larger size for these guys but also in the standard sizes.
Available currently as 40mm and 50mm widths as clip or house collar, full Martingale or reduced.
During the checkout process there is an option to add measurements of your dog's neck and widest part of their head. Please fill this information and any other requirement into that field so that we can make sure it will fit correctly.
A full Martingale is the traditional collar for Sighthounds and the design covers the full circumference. Whereas a reduced Martingale is closed with 25mm webbing which results in less bulk at the front of the neck. If you have a skittish dog I would recommend the full Martingale over the reduced.
