Animal Quote by Edward Custo
““A year-long study by the University of Pennsylvania, ending in 2009 and published in the journal Applied Animal Behavior Science (Elsevier), showed that aggressive dogs who were trained with aggressive, confrontational, or aversive training techniques, such as being stared at, growled at, rolled onto their backs, or hit, continued their aggressive ways. Non-aversive training methods, such as exercise or rewards, were very successful in reducing or eliminating aggressive responses.””
