I didn’t think I’d spend my career fighting for dogs to be allowed to play fetch. But here we are.
Four years ago, I noticed little hints of pet parents being warned about playing fetch. I had clients whose working dogs got no exercise.
“We used to play fetch, but the previous trainer told us to stop so he wouldn’t become a super athlete,” one Aussie owner told me. “The arch of the ball in the air causes adrenaline spikes,” one trainer wrote. “It causes compulsive disorder” is a common theme. “They are addicted”. The list goes on and on.
At that time, I warned that it would spread like wildfire, and indeed it did. Now, the concept that fetch is bad is in most pet households. Why do I care? Because many dogs are underenriched. Most dogs are underexercised. Taking away the one joyful thing they do is terrible. Especially when the claims are false.
Yesterday, I was tagged on a post about fetch. My followers know I’m pro-fetch (because I’m pro-happy and excited dogs). Heck, I wrote a chapter in my book about fetch.
When I saw the post, my heart sank. The post, with the click-bait “HERE’S THE SCIENTIFIC TRUTH NO ONE TALKS ABOUT,” had 900 shares. Then 1000. Now 2.1k.
I’ve tried so hard to stay out of these debates. I just want dogs to be happy, but the world is on fire, everyone is stressed, and we’re all focused elsewhere. But this morning, someone shared it with a cattle dog group. One commenter said, “I play fetch with my dog once a week, and now I’ll rethink that.”
And just like that, my heart snapped in half.
In 2.1k shares, there are countless guardians who will stop playing with their dogs because of that post.
So, I woke up this Sunday morning and found myself here, making this post, attempting to put a bandaid on the gushing chest wound of the assault on happy, excited dogs.
The first claim of the viral post is that fetch mimics the predatory sequence. This is the pattern that all predators use to hunt. They find the prey, then they stalk it. Next, they chase, then grab, bite, kill and consume. The poster says that fetch is bad because “the kill bite never comes” and reports that “the dog is neurologically left in a state of arousal.” I get it. When paired with words like “dopamine,” “adrenaline,” “and cortisol,” it sounds potentially bad.
If we are concerned about completing the sequence, we can rest easy knowing the dog does, in fact, “capture” its ball “prey.” If they want to shake it, they do. They can if they want to hold it with their paws and rip it apart with their incisors, instinctively acting out the “consume” part of the sequence.
But fetch isn’t a broken predatory loop. It’s a modified, learned behaviour that is naturally rewarding, fun to do, and often reinforced with positive feedback and the ball being thrown again.
Not every dog must complete the full sequence to experience satisfaction or neurological "closure." Many have been selectively bred not to complete it (e.g., gun dogs retrieving without damaging prey and herders bred for various tasks). You might see some of your breed’s version come out during fetch, like when a border collie stalks his ball.
There’s no evidence that fetch causes chronic stress. Cortisol spikes during activity, including play, but this is not pathological. It’s a normal response. Studies do not support the idea that fetch causes chronic arousal or leaves a dog dysregulated. Chronic stress is caused by uncontrollable, unpredictable stressors, not voluntary play.
Studies show that predictable, rewarding exercises like fetch can reduce stress when balanced with rest. The claim that “dopamine is not the reward chemical—it’s the pursuit chemical” is a half-truth. Dopamine is involved in wanting AND liking. If dopamine release from play were inherently harmful, food training, nose work, and toy rewards would also be "dangerous" because they rely on the same reward circuitry. But there’s no evidence that normal play dysregulates the brain.
A meta-analysis on canine behaviour problems (Tiira & Lohi, 2015) found that lack of activity is associated with increased problem behaviours, including anxiety and destructiveness. Dogs, especially high-energy breeds, need both mental and physical outlets. Fetch can absolutely be part of that. It’s not "coffee for a child with ADHD”. It’s more like recess for a kid who’s been sitting all day.
While play can resemble predatory behaviours (chasing, biting, shaking), which is why we have stuffy squeaky toys, tug toys, balls, herding balls and candy-coated ways to let our dogs kill things, it’s functionally and emotionally distinct. Play triggers positive affective states in the brain and is associated with dopamine, endorphin, and oxytocin release—not just adrenaline and cortisol. Studies in dogs and other mammals show that play is self-rewarding and contributes to stress regulation, not dysregulation.
We also know dogs can distinguish between real predation, acts of aggression, and sexual behaviour vs play. That’s the whole point of play. It’s like humans playing house when we’re kids. Dogs are acting out the real-life version of what they might need to do, from fighting to hunting prey.
Again, no peer-reviewed studies show that playing fetch daily creates “chronic sympathetic dominance,” weakens immune systems, or causes behavioural burnout. These claims rely on theoretical ideas, not research. In fact, routine play, when balanced with sleep, training, enrichment, and calm time, contributes to emotional regulation and well-being.
On top of all of the fake scientific-washed bu****it, the concept that it makes dogs less focused on their handler is where I really want to pull my hair out. Our dogs are literally focused on us for survival. They are captive animals, rarely getting more freedom than a zoo animal. They rely on us for everything from potty breaks to feeding, and these days, they can’t even sleep where they choose. I’ve never met a dog who is less apt to focus on his handler because of fetch, but if I do, I’ll congratulate him for having some agency in his day, some ability to not care what the human is doing.
In fact, the very act of fetching and retrieving IS directly tied to the “level of synchrony between human and companion animal.” Delgado MM, Stella JL, Croney CC, Serpell JA. Making fetch happen: Prevalence and characteristics of fetching behaviour in owned domestic cats (Felis catus) and dogs (Canis familiaris). The very concept of fetch is believed to be tied back to days when it was helpful for us to have dogs bringing back animals killed with projectiles, something we still use the behaviour for to this day in hunting breeds.
If you ARE worried your dog is compuslive or “addicted”, know this. NO TRAINER IS QUALIFIED TO MAKE THIS DIAGNOSIS. Especially when the diagnosis is coming because a dog is focused on the ball, jumpy, potentially a lot to manage, Barky, “pushy,” or otherwise doing what excited dogs do. Including not wanting to stop. Imagine, as a kid, if you were running into a playground, excitedly yelling and begging your mom for five more minutes when it’s time to go home, and someone said you were “addicted.”
Compulsive disorder in dogs still needs a lot of studying, but it is likely genetic is often made worse by underlying conditions, like pain. Stress and anxiety usually contribute along with a lack of exercise and enrichment. Your dog enjoying playing with a ball is not a diagnostic criterion. In fact, I use play, including fetch, to help my compulsive disorder clients.
All that to say, the original post will be shared. It will be shared a lot because it sounds real, because it’s clickbaity because it makes people feel like they might be harming their dog. And, as a result, well-meaning people are going to stop playing with their dog.
The last line, “He deserves you—not just the ball”, is what REALLY makes me mad. This gaslighty concept that guardians using fetch are somehow not giving their dogs a relationship, love or connection.
If you don’t want to play fetch with your dog, don’t. If you’re worried about joints or arthritis, I’m not going to tell you to do something that doesn’t feel right. But if you’re like me, and your dogs love games, play and fun, don’t let some post stop you from having fun with your dog.
