You’ve probably seen a dog chase its tail — sometimes even trying to bite it. But why do they do this? Live Science lists several possible reasons — and ways to curb the behavior. The animal hospital in Schertz, Texas, says little pups may not yet realize their tails are part of their bodies.
Another reason could be boredom, especially when pets are left alone for extended periods. “When a dog isn’t getting enough food or exercise, it can get bored,” said Russell Hartstein, a zoo psychologist in Los Angeles. For bored dogs, playtime or a walk can help.
Sometimes dogs chase their tails to get attention. Owners can either reward the behavior with attention or ignore it. Don’t scold the dog — punishment can make the behavior worse by giving it the attention it wants.
Behavior That Raises Concerns
Hannes Lohi, a genetics professor at the University of Helsinki, says some breeds are particularly prone to tail chasing. Breeds like bull terriers and German shepherds are among those more likely to engage in this behavior. Sometimes tail chasing points to physical problems: tail injuries, itching from parasites or fleas, anal gland issues, and more. Food allergies can also make dogs lick, bite, or chase their tails. In those cases, contact a veterinarian as soon as possible.
Ultimately, tail chasing may be linked to neurological disorders, such as a canine version of obsessive-compulsive disorder. In a 2012 study, Professor Lohi and his colleagues examined 368 dogs from four breeds that exhibited tail chasing behavior. They found that this behavior typically began between the ages of 3 and 6 months. Nearly half of the dogs that chased their tails also displayed other types of compulsive behaviors.
Lohi observed that dogs receiving dietary supplements, particularly vitamins and minerals, were less likely to “hunt” their tails. Additionally, spayed females engaged in this behavior less frequently, suggesting a hormonal connection. Lohi also said “tail chasers” were often more anxious and had been separated from their mothers earlier than other dogs.
Owners can often stop tail chasing by interacting with their dogs more, training them, and taking them outside regularly. That helps dogs feel less lonely or neglected.
