Study Finds Some Dogs Exhibit Addiction-Like Behavior Towards Their Favorite Toys

A recent study by behavioral biologists at the University of Veterinary Medicine in Vienna reveals that some dogs display addiction-like behaviors toward their favorite toys, such as tennis balls or squeaky plushes. Involving 105 dogs of various breeds known for toy motivation, researchers observed behaviors that parallel human compulsions found in gambling or gaming addiction. About one-third of the dogs showed intense fixation, ignoring food and social interactions while obsessively seeking access to their toys. The study highlights dopamine-driven reward circuits as the neurological basis for this behavior, particularly in breeds bred for intense focus like Belgian Malinois and Border Collies. Although many toy-focused dogs remain healthy and motivated, for a notable subset, play becomes excessive and maladaptive, posing potential welfare risks such as stress or injury. Scientists introduced a new metric to assess craving and loss of control in dogs, and ongoing research explores links with ADHD-like symptoms. The findings deepen understanding of canine psychology by showing how their brain chemistry parallels human addiction mechanisms, urging pet owners to recognize when play transforms into unhealthy compulsion.
