Do dogs act differently when in pain?

Dogs who are in pain may limp or show signs of stiffness. Because dogs can’t speak, it can sometimes be difficult to spot when they’re in pain, whether it be from injury or an underlying issue. However, there are a number of behavioural signs, some more obvious than others, that can indicate pain in dogs. Just like humans, dogs suffering pain may go off their food. If your dog’s appetite suddenly changes or you notice any form of inappetence, you should seek veterinary advice, as this could be a symptom of a dangerous ailment. Often, our dogs suffer in silence.

Most people can recognise physical signs that their dog may be in pain, such as limping or not wanting to (or being able to) jump on or off the sofa or bed. But often, the signs can be much more subtle. When thinking about how pain can affect a dog’s mental health, certain behaviours can give clues that may warrant investigation: Apparent unprovoked aggression. It makes sense that a dog in pain may not tolerate being approached or touched. Initial warning signs could include moving away, not making eye contact, licking their lips, or growling. Toileting inside can often be seen in older, arthritic dogs who may not be able to get up and out to the garden in time, so although the cause is actually a physical problem, a lot of owners see it as a behavioural change. Excessive licking can also be a sign, as a dog may lick at a painful joint, sometimes obsessively. Hiding away may be because they don’t want to physically be touched but also can be because they are just not feeling great, and the pain is starting to affect their mental health. Disruption to sleep patterns can also be an indicator, as dogs in pain can suffer with their sleep, and it has also been shown that the perception of pain increases at night due to a lack of other distractions. Increased clinginess can be a sign as well, as dogs will often see their owners as their ‘safe space’ and so are likely to seek out their attention if they are in pain or feel unwell.

Dogs can’t tell us they feel pain – many are often experiencing a degree of pain which makes their behaviours worse. And sometimes the way they show that can be really odd – such as eating grass, fly snapping at nothing in the air, or aggressive outbursts. Pain doesn’t just mean limping or whimpering. Dogs are masters at hiding discomfort, and often, behavioural changes are their only way of communicating their pain. By the time the dog is visibly limping, then the pain is pretty bad. Growling or snapping when disturbed if sleeping or resting. Growling when someone approaches them if they’re lay on the sofa, or leans on them for a cuddle etc. Snapping at other dogs if they sniff a sore area like their back legs or paws. Being hyperactive and unable to settle or keeps getting up to change position. Less keen to get involved in activities they usually love doing like playing. Eating things they shouldn’t such as stones, grass or unusual items can be a sign of tummy issues. Changes in Activity Level: A once-energetic dog might become reluctant to play, go for walks, or even climb stairs. Increased Vocalization: Whining, groaning, or barking more than usual can be signs of pain, especially when lying down or getting up.
