Some Tentative Body Proportions

Yinrih are about 200 cm long from the tip of the nose to the tip of the tail. The back is about 34 cm wide and they stand about 76 cm at the withers. The tail is slightly longer than the distance from the tip of the nose to the base of the tail, allowing them to comfortably bring objects wrapped in the tail up to the mouth and nose.

The back and chest are wider than a dog's, and their rear feet are plantigrade. Their limbs are very muscular, optimized for strength rather than speed or endurance. Because Yih has 12% lower gravity compared to Earth, yinrih may not be as dense as you'd expect animals of their size to be.

Give this fellow a vulpine head and fur, and increase his size a fair bit, and you've got a yinrih more or less.
