Can pain cause behaviour problems in dogs?

While we often think of pain causing limping, crying or reluctance to exercise, it can also influence how a dog feels, learns and responds to the world around them. Indeed, in some cases, a change in behaviour may be one of the earliest signs that a dog is experiencing discomfort. In cases of chronic pain, it can be the only sign. This means understanding the possible relationship between pain and behaviour is an important part of any behavioural assessment.

 

 

How can pain affect behaviour?

Pain doesn't just affect the body, it can also affect emotions. A dog living with discomfort may become more vigilant, less tolerant of handling, more easily startled, more defensive over their body or resting areas, more sensitive to noise, and less sociable. They may also have a lower threshold for aggression. Some dogs become quieter and more withdrawn, while others become more reactive or defensive. Every dog responds differently to pain.

 

 

Signs that pain could be affecting your dog's behaviour

Behavioural changes linked to pain can vary depending on the individual dog and the nature of their discomfort. You may notice your dog:

• Growling or snapping when touched.

• Becoming reluctant to be groomed or handled.

• Avoiding being picked up.

• Hesitating before jumping onto furniture or into the car.

• Showing less willingness to jump off furniture or their bed.

• Becoming reluctant to go for walks.

• Sleeping more or less than usual.

• Becoming less sociable.

• Seeming unusually irritable.

• Becoming more sensitive or reactive to noises.

• Guarding their body or resting areas.

• Seeming more vigilant or jumpy.

• Reacting to things that never used to bother them.

• Showing unpredictable or uncharacteristic aggression.

 

These signs don't necessarily mean your dog is in pain, but they are all worth discussing with your vet.

 

 

Conditions that may influence behaviour

Many medical conditions can affect behaviour, including:

• Arthritis.

• Other orthopaedic conditions.

• Dental disease.

• Ear infections.

• Skin conditions.

• Anal gland problems.

• Gastrointestinal disease.

• Neurological conditions.

• Injuries.

 

This isn't an exhaustive list, and not every dog with these conditions will develop behavioural changes. Some medications can also influence behaviour, so if your dog’s behaviour has changed since starting a medication, it’s important to let your vet know.

 

 

What if my dog's health check was normal?

Sometimes owners tell me that their dog has already seen the vet and been given the all-clear. This is fantastic, but it doesn’t necessarily rule out pain. Some conditions can be subtle, intermittent or difficult to identify during an initial examination. Additionally, some dogs experience high levels of stress during veterinary visits, which can mask signs of pain or make it difficult for the vets to conduct a thorough examination.

 Therefore, whilst clean bills of health from vets are reassuring, it doesn’t necessarily mean that pain can be excluded and, in some cases where pain is strongly suspected, further investigations may be deemed necessary down the line.

 

 

Why treating behaviour alone isn't always enough

If pain is contributing to a behavioural problem, training or behaviour modification alone is unlikely to resolve it. If the root cause is pain or discomfort, lasting behavioural change is likely to be limited until this is identified and managed.
