What is your dog's body telling you?

Dogs say most of what they feel with their bodies. The loud signals, a growl or a snap, come late. The quiet ones come first: a lick of the lips, a yawn, a head turned away. Those are the ones owners miss.

…yawning, and nose licking were more rarely reported, suggesting that few owners are able to correctly interpret and intervene in early stages of stressMariti and others, Journal of Veterinary Behavior, 2012

That line comes from a survey of 1,190 dog owners. This page covers the whole range, from a relaxed dog to a frightened one, with a one-page sheet you can print. The warning signs before a bite, in the order a dog shows them, are on the ladder page.

It prints on one page, without the rest of this page.

Relaxed, playful and interested

A relaxed dog looks loose. Nothing about it is held tight.

The dog's mouth is open and relaxed, ears are in a natural position, and their eyes are a normal shape.RSPCA, Understanding your dog's body language

The play bow is the clearest invitation a dog makes: front legs down, rear end up.

The quiet signs of stress

These are the signals that come before anything louder. They mean the dog is uncomfortable, and they are the best moment to help: give it room, stop what is bothering it, or move it away.

Yawning and lip licking may be early signs of stressASPCApro, Canine body language tips, updated May 2026

Whale eye is when the dog turns its head a little but keeps looking, so the whites of its eyes show.

The veterinary guidelines add posture. A worried dog carries itself lower than usual, and a frightened one drops even further.

Freezing deserves its own line, because it is easy to read a still dog as a calm one.

A wagging tail is not always friendly

A wag means the dog is stirred up about something. Whether that something is good or bad is in the rest of the tail and the rest of the body.

When the tail is held high with short, stiff, rapid movements, it is usually a signal of tension, high arousal, or potential aggression.ASPCApro, Canine body language tips, updated May 2026

A 2024 review of the research on tail wagging came to the same place.

Tail wagging is frequently associated with both positive and negative arousalLeonetti and others, Why do dogs wag their tails?, Biology Letters, 2024 (CC BY 4.0)

Why the growl matters

A growl is a warning, and a warning is useful. A dog punished for growling does not stop being frightened. It learns to skip the warning, and the next step on the ladder is a bite.

…often suppress signals of impending aggression, rendering any aggressive dog more dangerous2015 AAHA Canine and Feline Behavior Management Guidelines

The American Animal Hospital Association wrote that about aversive training, the kind that relies on punishment. When a dog growls, stop what you are doing, give it space, and work out what caused it.

When the signs are new

A dog that starts showing these signs suddenly, or far more often than before, may be in pain. In a review of dog cases seen by behavior specialists, pain was common.

…a conservative estimate of around a third of referred cases involve some form of painful condition, and in some instances, the figure may be nearly 80%Mills and others, Animals, 2020

So a vet visit comes before any training plan. The scared dog page has the rest: what helps a fearful dog, what makes it worse, and a simple check of whether a dog wants to be petted.
