Understanding pain in dogs: It’s adaptive for dogs to hide pain. Unless you’re a greyhound!

The challenge of chronic pain in dogs

While dogs are adept at concealing pain, certain breeds like greyhounds are notorious for their dramatic reactions to acute pain—often referred to humorously as the “greyhound scream of death.” Chronic pain, however, is subtler and can be masked as dogs adapt over time.

This adaptation can affect:

• Sleep
• Appetite
• Energy levels
• Sensitivity to stimuli

These changes impact a dog’s emotional regulation and behaviour, much like humans experience.

How pain affects dog behaviour

Increased sensitivity to stimuli is a common response in dogs experiencing pain, as it can help them avoid danger by reacting more quickly. This heightened alertness can lead to:

• Difficulty achieving deep, restorative sleep
• Disruptions in the sleep cycle, affecting physical repair and regulation
• Escalating stress levels due to poor sleep and constant vigilance

These factors can decrease a dog’s ability to regulate emotions, potentially leading to increased irritability or frustration, impacting their learning and behaviour. For instance, a dog in pain might become more protective of personal space or exhibit increased resource guarding.

Misconceptions about active dogs and pain

A dog’s willingness to walk or chase a ball doesn’t necessarily mean they are free from pain. Motivation for enjoyable activities can override pain temporarily, thanks to adrenaline, which can mask discomfort. This is similar to how humans might temporarily overcome pain in high-adrenaline situations.

Even subtle signs of discomfort, such as minor gait changes, can be easily missed unless specifically trained to spot them.

Take-home advice for dog owners

1. Rest and recovery: Allow your dog 1-2 days of slower, shorter walks to prevent exacerbating minor injuries, particularly for active or sporting dogs.
2. Manage activity: Regulate your dog’s pace during walks to help prevent injuries from explosive movements.
3. Vet checks: If you notice any changes in your dog’s behaviour, sensitivity, or energy levels, consult a vet to rule out pain as a contributing factor.
4. Professional care: For behavioural issues, ensure any professionals involved have a referral from your vet, confirming that behaviour isn’t influenced by underlying medical conditions.
