Not all brands share the same sizing measurements.

Different designers and manufacturers use their own size charts.

A size SMALL from one manufacturer might be a size XS from another.

Even if you think you know your dog’s size, always measure your pet for chest girth and length and look at the size chart to confirm the size before your purchase.
