Mitigation model 2, use of cooling after exercise in summer: canine variables tested through binary logistic regression for their association with coat use in winter to facilitate activity. Increased odds of coat use are indicated by an odds ratio greater than one; an odds ratio lower than one indicates reduced odds of coat use.
