Not recommended
The M/L size was too small for my 17 kg French Bulldog. She is not overweight — she is simply a larger and taller-built French Bulldog. Unfortunately, the diapers don’t seem to be designed with the French Bulldog body shape in mind. They slip off immediately and don’t stay securely in place. Even if the size had been correct, I don’t think the shape or design would work well for her. The sizing and fit are very misleading.
