Understanding dog behaviour


Understanding dog behaviour

As a dog owner, it’s always a good idea to keep an eye on your dog’s behaviour and be on the lookout for any changes, as these can be a sign that something’s wrong. Use this guide to help you recognise important body language signals and get to know how your dog is feeling. 

A happy dog

A dog who is happy will be relaxed.

1. Dog has a relaxed body posture and smooth hair, the mouth is open and relaxed, ears are in a natural position, the tail is wagging and the eyes are a normal shape.

2. Dog is inviting play with bottom raised, smooth hair and a high wagging tail. Eyes are a normal shape, ears are in a natural position and they may be barking excitedly.

3. Dog’s weight is distributed across all four paws, hair is smooth, tail is wagging, face is interested, alert and relaxed and their mouth is open.

A worried dog

These dogs are telling you that they’re uncomfortable and don’t want you to go near them.

An angry or very unhappy dog

These dogs aren’t happy and want you to stay away or go away.

If you’re concerned about your dog’s behaviour, speak to your vet first. They may then refer you to a clinical animal behaviourist.
