    In 48 Labrador Retrievers studied as pairs for life, dogs fed 25% less than their pair mates had a longer median life span and later onset of chronic disease. Used in: blog/is-my-dog-overweight.html
  5. Mech LD (1999). Alpha status, dominance, and division of labor in wolf packs. Canadian Journal of Zoology 77(8):1196-1203. doi:10.1139/z99-099
    Based on 13 summers observing wild wolves on Ellesmere Island, concludes that a typical wolf pack is a family led by the parents, not a group constantly fighting for alpha status. Used in: blog/alpha-dog-myth.html
