When a dog enters a shelter, it is just as important to pay attention to the dog’s behavioral health as it is to address the dog’s physical health. The Match-Up II Shelter Dog Rehoming Program includes a thorough multi-part behavioral evaluation designed to help shelters learn about the personality and behavioral needs of each dog. Every dog is considered to be an individual, having specific requirements and desires, regardless of breed or background. Match-Up II can often reveal problem behaviors, such as food aggression, that can be helped through the behavior modification techniques described in this section.
