Differences in Toy/object attachment between dogs average and extreme on Ball/toy and/or Food responsiveness. Dogs high on Ball/toy and low on Food responsiveness (HTR) had higher scores than dogs in the other groups, except for dogs high on both Ball/toy and Food responsiveness (HTFR) or dogs average on Ball/toy and Food responsiveness (ATFR, i.e., average on reward responsiveness) on Toy/object attachment. Dogs high on both Ball/toy and Food responsiveness (HTFR) scored higher than dogs average on reward responsiveness (ATFR). The error bars represent +/− 2 SE.
