Dog trancing is a behavior characterized by slow, repetitive movements, such as walking back and forth under objects that lightly touch the dog's head or back.
Dogs exhibiting this behavior often appear still or “frozen,” with a distant expression and can be difficult to distract.
Common objects that dogs may rub against anything at a height accessible for rubbing.
While this behavior has been noted in various breeds, it appears more frequently in dogs prone to compulsive behaviors, although no direct link has been confirmed.
The exact cause of dog trancing remains unclear; it may be a benign behavior that dogs find pleasurable, though veterinary consultation is recommended to rule out medical issues such as seizures.
If a dog begins trancing suddenly, exhibits other behavioral changes, repeats the behavior excessively, or appears lethargic afterward, a veterinary evaluation is advised.
Once medical concerns are ruled out, consulting a certified trainer or behaviorist may be helpful.
To manage trancing, especially when it occurs in inappropriate places, owners can use positive interrupters to redirect attention, modify the environment to limit access, and increase enrichment activities such as puzzle toys, interactive feeding, and exercise to reduce boredom or stress.
Generally, dog trancing is considered harmless, but monitoring the behavior and seeking professional advice when necessary ensures the dog’s well-being.
