Dog Friendly Co harness sizing
Dog Friendly Co’s No-Pull Dog Harness chart lists chest girths from 39cm to 103cm across 6 sizes. Does not start as small as most, so very small dogs need another brand. It also stops lower than most, so the largest dogs fall off the end of its range.

This chart is the No-Pull Dog Harness. Dog Friendly Co make other harnesses, and a chart published for one is not automatically right for another — check the box before ordering a different model.
What Dog Friendly Co calls the same dog other brands would
Letter sizes do not travel between brands. For a chest measurement of 71cm, the finder recommends Dog Friendly Co M using chest girth alone. Also covered by: L. The same measurement gives these chart results:
- Julius-K9 — 1; also covered by 0, 2
- Ruffwear — M
- PetSafe — Medium; also covered by Medium/Large, Large
- Kurgo — Large; also covered by Medium, X-Large
- Blue-9 — M; also covered by M/L
- Rabbitgoo — XL; also covered by L
- Puppia — XL; also covered by L
- PetSafe 3 in 1 — Medium
- PawSafe — M; also covered by L, S
- Wonder Walker — Medium; also covered by Large, Small
- Top Paw — gap in the published chart. 71cm falls in a gap in Top Paw's chart, between Medium (up to 68.6cm) and Large (from 71.1cm). Re-measure first — a reading this close is often a little off. If it holds, the Medium would be at its loosest and the Large at its tightest.
These recommendations use chest girth alone. The size finder also considers published weight guidance when you supply weight. If you already know your dog’s Dog Friendly Co size and want it at every other brand, convert it directly — the tool opens on Dog Friendly Co and reads out every size that overlaps.
Where the size ranges meet
Dog Friendly Co has overlapping size bands. For example, M and L both cover 67–75cm. The finder recommends the most central match by chest girth and keeps the other covering sizes visible; published weight guidance can help choose when weight is supplied.
Some size pairs also share a single endpoint: XXS / XS at 45cm; XS / S at 53cm. At each of these exact measurements, both named sizes cover the chest.
The published chart leaves a gap: S ends at 61cm and M starts at 62cm. No listed size covers a measurement strictly between those endpoints. Re-measure and ask the maker before choosing; the finder shows the gap without assigning a size.
Near the bottom of a size’s range, the straps run close to their tightest; near the top there is little adjustment left. The size finder shows that position and every covering alternative.
