Generic affiliate blogs write "The 10 Best Dog Harnesses" to maximize SEO search volume. They reuse generic manufacturer XS-to-XL tables that fail in practice. We built a structured reference database.
One dog size is not equivalent to another. An M size in Julius-K9 sitting at 58cm sits right on the border of a Ruffwear XS or S. This fitting inconsistency is responsible for roughly 50% of pet equipment returns.
Never buy gear based on breed or weight alone. Girth and torso outline determine pressure distribution.
We normalize brand size tables using physical sizing bounds and document our verification dates.
