Why do dogs get the zoomies? The truth about FRAPs

It usually starts with a look. Ears go back, the back end drops a little, and then your dog is gone: tight laps around the coffee table, a skid on the rug, a hairpin turn off the couch and a victory lap down the hall. A minute or two later it ends as suddenly as it began, and your dog flops down panting like nothing happened.

Owners call it the zoomies, the crazy eights or midnight madness. Cornell University’s College of Veterinary Medicine notes the official term is frenetic random activity periods, or FRAPs, which is the most scientific way anyone has ever described a dog losing its mind with joy.

Here is the honest part. Cornell’s vets say there is no known specific cause of FRAPs in dogs. Nobody has run a big controlled study of them, and behavior scientist Marc Bekoff has written that detailed research on zoomies is still needed. What experts agree on is a working explanation: FRAPs seem to be a way to release pent-up energy, or perhaps to let off stress.

Both halves fit what owners see. A dog that has been cooped up, held still or kept waiting has energy with nowhere to go. A dog that just put up with something it didn’t love (a bath, a nail trim, a vet visit) may be shaking off the tension. Stanley Coren adds a third, happier reading: many vets describe zoomies as an excited expression of happiness, much like a small child who bursts into a dance at the word “ice cream.”

Zoomies are “random” in name only. Most dogs have favorite moments, and Cornell lists the usual suspects:

• Right after a bath or a grooming session, probably the most famous trigger of all.
• Being let out of a crate, off a leash or out of any kind of restraint.
• You coming home after work, or a favorite visitor arriving.
• Late evening, the classic “midnight madness” slot.
• After pooping, which baffles owners but is common enough to make the official list.
• Play or training that got the dog a bit overexcited.

The post-bath sprint makes sense under both theories. The dog has just been held still, soaked and scrubbed, and now it is free and damp. Some dogs seem to be drying themselves on every surface they can reach. If your dog is a reliable post-bath zoomer, a self-serve wash with a raised tub and a dryer gets most of the water off before you let go: see our guide to using a self-serve dog wash.

Yes. FRAPs are most common in puppies and young dogs and tend to fade with age, though plenty of adult and even senior dogs still have the occasional burst for life. Breed and personality matter too: a young herding or sporting dog with a desk-bound week is a prime candidate.

Dogs aren’t the only ones. Coren points to similar bursts in ferrets, rabbits (whose leaps and twists are known as “binkies”), elephants and human toddlers. Bekoff has also watched zoomies spread at the dog park: one dog takes off, and others join in.

Usually not. Cornell says zoomies themselves won’t hurt your dog, and Coren notes they typically last a minute or two and need no intervention. The risk is the setting, not the behavior. A dog at full speed can crash into furniture, slide on a slick floor or knock over a small child.

• Steer zooms away from stairs, hard slippery floors, glass doors and roads.
• Outside, use a fenced yard or enclosed field; grass is the kindest footing.
• Don’t chase your dog. To most dogs that is an invitation to keep going.
• If you need it to end, stand still and calmly call your dog to you, or toss a toy or treat somewhere safe.

If your dog zooms several times a day, or at awkward moments, that may simply be a sign it needs more to do. Cornell suggests more exercise (hiking, fetch, swimming) plus mental work like scent games and training. For a high-energy dog home alone all day, a few days a week at a dog daycare can take the edge off.

Happy zoomies look loose and wiggly: a bouncy gait, maybe a play bow, tongue flapping out. Not every frantic run is happy, though.
