This is the first warm coat that has fit my German Pinscher, so we are delighted with it. German Pinschers tend to have slender necks, deep chests, and a moderate tuck at the loin. That makes it hard to get a good fit. Either the coat is too tight in the chest, or it flaps around and twists at the loin. This puffer coat does not do that. I wish it came in more colors, however, the blue is quite attractive.
