New research suggests that certain dogs exhibit an astonishing attachment to their toys, prioritising play over essential activities such as eating, resting, and even interacting with their human companions. This intriguing study, recently published in the journal *Royal Society Open Science*, sheds light on behaviours that might be interpreted as addiction-like in nature among various breeds.

The study involved nearly 1,700 dogs from 33 countries, with their owners asked to rank their pets based on statements related to their attachment to toys. Phrases like “My dog is a ball junkie” and “When my dog is prevented from playing, he or she becomes stressed and agitated” were part of the survey to help gauge the intensity of this obsession.

Distinct patterns emerged regarding which breeds are most prone to show these behaviours. Sheepdogs, terriers, and retrievers were identified as the primary breeds that may exhibit toy-related addiction behaviours, such as distress when their favourite toys are taken away. This research highlights a peculiar phenomenon where certain dogs seem to be unable to disengage from their toys, even in the face of food or the desire for companionship.
The findings indicated that dogs displaying the highest scores on the obsession scale showed signs that could be reminiscent of addiction, including a heightened level of focus and excitement towards their toys. These canines reportedly struggled to refocus their attention even when their toys were no longer present. Such persistent behaviour is often characterised by a compulsive need to play that can overshadow even fundamental needs like sustenance.
While the research draws parallels between dog behaviours and human-like addictions, the researchers caution against equating the two directly. Alja Mazzini and Stefanie Riemer, the study’s authors, emphasised that their work is intended to outline behavioural patterns that are somewhat similar to those seen in human addiction, rather than asserting that dogs experience addiction in the same way humans do.
The study builds on previous work by Mazzini and Riemer, who conducted an earlier investigation involving 105 dogs noted for their high play motivation. From this smaller sample, they found that a substantial number exhibited behaviours congruent with addiction-like traits. The current research extends those findings by analysing a larger and more diverse population of dogs and gathering insights from their owners regarding daily interactions with their favourite toys.
The results from this extensive study may have broader implications for understanding how to best care for these beloved pets. Recognising the signs of excessive toy attachment could guide owners in managing their dog’s playtime and ensuring a balanced lifestyle. It may prompt owners to be mindful of their dog’s engagement with toys while also fostering healthy social interactions.
As our understanding of canine behaviour continues to evolve, studies like this one are crucial for recognising the nuances of how dogs interact with their environments. These insights could lead to better practices in training and care, ensuring that dogs’ physical and emotional needs are met, even in the face of their undying love for a simple toy.
The research illuminates the profound bond between dogs and their toys, indicating that for some pets, playtime can evoke feelings of euphoria that are hard to replicate through other means. As pet owners look to deepen their understanding of their canine companions, this study represents an important step in unveiling the complexities of dog behaviour.
