The neck guard by Puppia is a new product concept that was created with dogs that have delicate throats and have tracheal problems. Its design includes a traditional collar which is integrated in a neck guard (wider and slightly thick and soft material) to prevent dogs from choking. The Barron Neck guard is a fall/winter neck guard that features a removable checkered pattern guard. It is available in Wine and Grey in sizes ranging from Small to Extra-Large. Please note that because these products were created with small/medium dog breeds in mind, larger sizes (i.e. Large, Extra-Large, etc.) do not necessarily mean larger breeds. Please refer to image of the size chart. As a general rule of thumb, if your dog falls in between sizes, it is usually better to go up a size. Weight figures are for estimates only. Always use actual measurements.
