Leash walking
Why does my dog pull backward and seem to choke itself on the leash?
Last updated 23 September 2026 · How we write and check this
Short answer
A dog that suddenly pulls backward, sometimes called crab walking or a panic reaction, is usually startled or fearful of something, trying to create distance rather than move forward, which can tighten a collar around the throat if that is what the dog is wearing. Switching to a well fitted harness removes the choking risk while you address the underlying fear.
What is actually happening
This backward pulling is a flight response: your dog wants to get away from something, a loud noise, an approaching dog, an unfamiliar object, and the leash is the only thing stopping that escape. On a collar, this can create real pressure on the trachea, sometimes enough to cause coughing or brief gagging.
Switching to safer equipment
A harness with a snug but comfortable fit distributes pressure across the chest and shoulders instead of the throat, so even a strong backward pull does not risk the same choking sensation. Check the fit allows two fingers to slide under any strap without it slipping over the head.
Addressing the fear behind it
Once equipment is safer, work on identifying what specifically triggers the backward pull, whether it is a certain sound, surface, or type of object, and build confidence gradually by exposing your dog to a milder version of it from a distance, pairing it with treats.
Key takeaways
- Backward pulling is usually a fear or flight response, not defiance.
- A collar can put real pressure on the trachea during a strong backward pull.
- A properly fitted harness removes the choking risk during these moments.
- Identify and gradually desensitize the specific trigger from a safe distance with treats.
