Abstract
We measured nipple sizes of 29 captive wolves (Canis lupus), of known breeding histories, throughout the year and tested distinctions among various known breeding statuses of 20 wild wolves examined in northeas tern Minnesota from May through September. For ca. 8 mo of the year on ly breeders and nonbreeders can be classified. Distinctions between cu rrent and former breeders were not reliable.
