Dog clothing isn’t one-size-fits-all — because dog bodies aren’t one-size-fits-all. In this Boston Made Pets breed fit guide, we explain why most dog apparel sizing systems fail and how different body types (long-back, deep-chest, broad-shoulder, and petite breeds) require different cuts to stay comfortable. Learn the most common breed-specific fit problems, why dogs reject clothing even when it “fits,” and how to choose wearables that support movement, confidence, and real comfort — the Boston Made Pets way.
