Why dogs do it
Why does my dog pull toward other dogs?
A dog straining toward every passing dog can look like the same problem every time. It rarely is. The pull of a happy greeter, a frustrated one and a nervous one feel similar through the leash but come from different places, and each needs different help. This page explains the likely reasons and how to read them; our how-to guide on the topic covers the step-by-step method.

Three likely drivers
Excited, frustrated or worried: reading the pull.
Excitement tends to look loose: a wiggly body, soft eyes, play bows and a curved approach when allowed. Frustration often starts the same way, then tips over when the leash stops the dog short. Whining, high-pitched barking and a stiffening body can appear as the gap stays closed. Many dogs who greet happily off leash become frustrated on it, simply because the greeting they expect keeps getting blocked.
Reactivity rooted in worry usually looks different up close. The dog may freeze, stare hard, raise its hackles or bark in a lower tone, and the pull can be a rush to drive the other dog away. A dog who snaps, lunges or backs off at close range is likely uneasy. Please do not let your dog reach a stranger's dog just to find out; watch from a safe distance instead.
- Loose, wiggly body suggests excitement
- Whining at leash's end suggests frustration
- Hard stare suggests worry
- Raised hackles and low barking
What to do first
Vet, training, and the right format to start.
Book a vet visit if the pulling arrived suddenly, comes with new irritability, or your dog seems sore when the harness or collar goes on. Discomfort can make a sociable dog edgy. Otherwise, this is a training matter. First steps are management: more distance from other dogs, quieter routes and times, and no on-leash greetings for now. Our how-to guide on pulling toward dogs covers the exercises themselves.
For a keen or frustrated greeter, On-Leash Foundations works on loose-leash walking, heel and everyday distractions, while Private Training gives you a one-hour session and a plan to practice at home. If worry, lunging or a bite history is part of the picture, Behaviour Rehab works on reactivity at the dog's pace after a full assessment. We recommend a format at the consultation, and we say so when the lighter option will do.
Asked and answered
The questions people ask us.
Why does my dog pull toward other dogs but not people?
Other dogs are often the most exciting, or most worrying, thing on a walk. The same reading applies: loose and wiggly suggests keenness, while stiff and staring suggests unease.
Should I let my dog say hi so it stops pulling?
Letting the pull earn a greeting often teaches a dog that pulling works. It is also a risk if the other dog, or your own, is less friendly than it looks.
Is my dog reactive if it barks while pulling toward dogs?
Not necessarily. Frustrated greeters bark too, usually higher-pitched and with a looser body. Watch the whole dog and, if in doubt, get a professional assessment.
Why did my dog suddenly start pulling toward other dogs?
A sudden change can follow a scary encounter, adolescence or physical discomfort. Start with a vet check, then look at what changed around the time it began.
