Training & Behavior

Two dogs are wrestling by the gate. One is on its back, the other standing over it, and both are making a fair amount of noise. Half the people watching think it is a fight. The other half think it is fine. One of those groups is right, and which one depends on details most owners have never been taught to look for.

Dog parks are genuinely useful places. They are also where a large share of behavioural problems begin, usually because nobody was reading the dogs.

What healthy play looks like

Good play is loose. Bodies curve rather than stiffen, movements are bouncy and slightly exaggerated, and there is a comic quality to it. Watch for the play bow, front end down, rear up, which is a clear invitation and a reset button used throughout a session.

Play is reciprocal. Dogs swap roles: the chaser becomes the chased, the one pinned gets up and pins the other. A dog on its back during play is usually a willing participant, not a victim, provided it keeps re-engaging when released.

There are natural pauses. Dogs break off, shake themselves out, sniff the ground, then start again. That shake-off is a self-regulation signal and it is a very good sign.

Mouthing and growling occur in normal play. Play growls are lower, longer and less tense than real ones, and the mouth stays open and relaxed. Noise alone tells you very little.

The best test is simple. Hold the more assertive dog for a few seconds. If the other dog immediately comes back and asks for more, the play was mutual. If it takes the opportunity to leave, it was not.

Signals that things are turning

Stiffness is the first change. A body that goes still and rigid, even for a second, is a warning. Play is fluid; tension is not.

Watch the eyes. A hard fixed stare, or whale eye where the whites show as the dog looks sideways, means discomfort. Look at the tail: high and rigid with a fast stiff wag is arousal, not friendliness. A low tucked tail with a lowered body is fear.

Raised hackles along the shoulders and spine indicate arousal rather than aggression specifically, but they tell you the dog is highly stimulated.

Appeasement signals mean a dog wants the interaction to stop: lip licking when there is no food, yawning when not tired, turning the head away, sniffing the ground pointedly, or trying to move behind its owner. A dog doing these things is asking for help. Owners routinely miss this and then are surprised when the dog snaps.

Then there is the pattern most people mistake for play: one dog relentlessly chasing another that is trying to escape, with no role reversal, ears back, tail tucked. That is bullying, and if you have the chasing dog, you are the one who needs to intervene.

Group chase can also tip into something ugly quickly when three or more dogs pursue one. Break it up early rather than hoping it settles.

How to intervene without making it worse

Interrupt early and often. A cheerful recall every couple of minutes, followed by a brief pause and then release back to play, keeps arousal from stacking up. Dogs that never come out of play spiral upward until something snaps.

If you need to break up tense play, call the dogs rather than reaching into the middle. Move sideways or away rather than straight in, since approaching head-on adds pressure.

For a genuine fight, never put hands near the mouths. The wheelbarrow method, where two people each grab a dog's hind legs and back away, works when there are two adults. A loud sudden noise, a spray of water, or a coat thrown over the dogs can also interrupt. Then separate them fully and check for injuries, remembering that puncture wounds are often hidden in thick coats and need veterinary attention.

Afterwards, both dogs go home. Nobody learns anything useful in the ten minutes after a fight.

Basic human etiquette

Leash off inside the fence, not before, and never leave a lead trailing where it can tangle. Mixed on-lead and off-lead dogs is a common trigger, because a leashed dog cannot move away and feels trapped.

Do not congregate at the gate. That is the highest-tension spot in any park, since new arrivals get swarmed. Move into the open space.

Watch your dog, not your phone. This is the single most common failure and the reason most incidents escalate. If you are scrolling, you are not supervising, and someone else is managing your dog for you.

Pick up after your dog, every time. Do not bring food or treats into a crowded park, because it creates competition. Do not bring toys unless the park is empty, for the same reason.

Do not bring a female in season, an unvaccinated puppy, or a sick dog. And if your dog is having a bad day, go home. There is no obligation to stay for the full hour.

Dogs that should not go

Puppies under about four months, before their vaccination course is complete, and honestly under six months in busy parks, because a single frightening experience at that age can shape their view of other dogs for years.

Dogs with a bite history or serious reactivity. A park is not a rehabilitation venue, and working with a behaviourist in a controlled setting is the appropriate route.

Dogs that are genuinely fearful. Repeated exposure to something overwhelming does not build confidence; it usually deepens the fear.

Dogs that bully others, until they have been taught better impulse control.

Very small dogs in parks without a separate small-dog area, because size mismatches can turn into predatory drift with tragic results.

And, importantly, plenty of perfectly normal adult dogs simply do not enjoy group play. Many dogs mature out of it around two to three years old and would rather sniff a hedgerow with their own person. That is not a deficiency. Parallel walks with one known friend, sniffing walks, scent games and training sessions all meet a dog's needs without the chaos.

The best outcome at a dog park is boring: a loose-bodied dog playing in short bursts, checking in with you regularly, and going home pleasantly tired. If you are getting anything more dramatic than that, it is worth asking whether the park is really the right place for your dog.
