R’ Chanina ben Antignos says: [If] it has a wart on its eye, or the bone of its foreleg or hind leg is notched, or the bone in its mouth is split, [or] one eye is large or one is small, [or] one ear is visibly large and one is small, [it is a blemish,] but not if it must be measured. R’ Yehudah says: [Also, if] one of its testicles is twice the size of the other, but the Sages did not concur with him.
