Rukavina, G. M., Young, J. D., Grant, M. G.

Abstract

Our approach was to design a toy rotation scheme that would provide each dog with a different toy on a weekly basis. .. At the end of a 2-month evaluation period, only 4 out of the 9 toys (Dental Ball, Dumbbell, Havaball, and Kong) were completely successful at meeting our standards ... while also providing lasting appeal to our canine population.
