Dog Park Glossary – Canine Behavior Terms Explained

B

Bite Inhibition

A dog's ability to control the force of its bite. Puppies learn this from littermates. Dogs with poor bite inhibition pose a higher risk in park settings.

Body Check

When a dog runs into another dog at full speed. Sometimes playful, sometimes bullying. Context and the recipient's reaction tell you which.

C

Calming Signals

Subtle behaviors dogs use to diffuse tension — yawning, lip licking, looking away, sniffing the ground. Recognizing these prevents fights before they start.

Counter-Conditioning

A training technique that changes a dog's emotional response to a trigger. Used for reactive dogs to associate other dogs with positive things instead of fear.

D

Displacement Behavior

Normal behaviors that appear out of context when a dog is stressed — sudden scratching, sniffing, or shaking off when they're not wet. A sign your dog needs a break.

Double-Gated Entry

A safety feature at well-designed dog parks: two gates in sequence so a dog can't escape when someone enters or exits. Always close the first gate before opening the second.

F

Freeze

When a dog suddenly stops moving and becomes rigid. This is a red flag — it often precedes a bite. If you see a freeze, calmly remove your dog from the situation.

H

Hackles (Piloerection)

The hair along a dog's back and neck standing up. Can indicate arousal, fear, or aggression — not always aggression. Check the rest of the body language for context.

Hard Eye

A fixed, intense stare with a rigid body. Different from soft, blinking eye contact. Hard eye is a warning signal — the dog is uncomfortable and may escalate.

L

Littermate Syndrome

Behavioral issues that can develop when two puppies from the same litter are raised together — including extreme codependency and aggression toward other dogs.

O

Overstimulation

When a dog's arousal level exceeds its ability to self-regulate. Signs include frantic play, inability to respond to commands, and mounting. Time to leave the park.

P

Play Bow

The universal dog invitation: front legs down, rear end up. It means "everything that follows is play." Dogs who play bow frequently are generally good park citizens.

R

Reactivity

An exaggerated response to a stimulus — barking, lunging, or freezing when seeing another dog. Reactivity is often fear-based and can be managed with training. Not the same as aggression.

Resource Guarding

When a dog protects something it values — food, toys, a person — from other dogs or people. Common trigger for fights in dog parks. Never bring high-value items to a shared space.

S

Social Vibe Index™

USA Dog Parks' proprietary park rating system. Measures owner etiquette, dog social match quality, and observed conflict rate — not just fences and fountains.

T

Threshold

The point at which a dog is too stressed to learn or respond to commands. A dog over threshold needs to be removed from the environment and given time to decompress.

Trigger Stacking

When multiple small stressors build up until a dog reacts — seemingly out of nowhere. A dog that's fine for 20 minutes then suddenly snaps may have been stacking triggers the whole time.

W

Whale Eye

When a dog shows the whites of its eyes, usually while turning its head away. A clear stress signal. If you see whale eye, give that dog space immediately.

Z

Zoomies (Frenetic Random Activity Periods)

Those sudden bursts of wild running in circles. Usually a release of pent-up energy or excitement. Generally harmless, but in a crowded park, redirect to an open area to avoid collisions.
