My dog is becoming aggressive....could it be pain?
Dogs bring joy, love, and laughter into our lives. However, beneath their wagging tails and playful demeanour, dogs may sometimes conceal feelings of discomfort or distress, particularly when experiencing pain. The correlation between dog aggression and pain is a topic of growing interest among veterinarians, behaviourists, and dog owners alike. In this blog, we delve deeper into the relationship between aggression and pain, with a particular focus on recognizing the subtle signs of pain in our canine companions.
Understanding Dog Aggression
Aggression in dogs is a multifaceted behavioural trait that can manifest in various forms, including growling, barking, snapping, or biting. While some dogs display aggression due to fear, territoriality, or lack of socialization, others may exhibit aggressive behaviours as a response to underlying physical discomfort or pain. It's important to recognize that aggression is often a communication tool for dogs, a way to express their feelings and protect themselves when they feel vulnerable.
The Link between Aggression and Pain
Pain, whether acute or chronic, can significantly influence a dog's behaviour and temperament. Unlike humans, who can verbally articulate their discomfort, dogs may resort to aggression as a means of communication when experiencing pain. This aggression serves as a protective mechanism, signaling their distress and attempting to prevent further discomfort. However, since dogs cannot verbalize their pain, aggression may be misinterpreted or overlooked by owners, leading to inadequate management of the underlying issue.
Types of Pain-Related Aggression
Pain-related aggression in dogs can manifest in various ways, depending on the underlying cause and severity of discomfort. These manifestations are often subtle and nuanced, requiring keen observation and understanding from dog owners. Some common types of pain-related aggression include:
Territorial Aggression: Dogs may become territorial and aggressive, especially when in pain, as they perceive their space as a safe haven where they can minimize potential threats and avoid further injury. Subtle signs of territorial aggression may include tense body posture, guarded behaviour around certain areas of the home, and heightened alertness to perceived intruders.
Resource Guarding: Dogs in pain may exhibit heightened possessiveness and aggression over their food, toys, or other resources, as they associate these items with comfort and security. Subtle signs of resource guarding may include stiffening when approached while eating, reluctance to relinquish toys or objects, and displaying defensive body language around valued possessions.
Handling Aggression: Dogs experiencing pain may become reactive or aggressive when handled, restrained, or touched in specific areas of their body that are sensitive or painful. Subtle signs of handling aggression may include flinching, withdrawing, or growling when touched in particular regions, such as the ears, paws, or hips.
Fear Aggression: Chronic pain can exacerbate a dog's fear response, leading to heightened aggression towards perceived threats or unfamiliar stimuli. Subtle signs of fear aggression may include trembling, cowering, lip licking, and avoidance behaviours in response to specific triggers or situations.

Altered Gait or Movement: Dogs may exhibit subtle changes in their gait or movement patterns, such as stiffness, hesitation, or reluctance to jump or climb stairs.
Changes in Posture or Body Language: Subtle alterations in posture, such as hunching or guarding certain body parts, can indicate underlying discomfort or pain.
Decreased Appetite or Interest in Activities: Dogs may show subtle changes in appetite or interest in activities they previously enjoyed, such as playing fetch or going for walks.
Increased Restlessness or Irritability: Dogs experiencing pain may display subtle signs of restlessness, pacing, or agitation, as they struggle to find a comfortable position or alleviate discomfort.
Changes in Sleeping Patterns: Subtle shifts in sleeping patterns, such as increased or decreased sleep duration, frequent waking, or restlessness during sleep, may suggest underlying pain or discomfort.
Pain scoring is a valuable tool utilized by veterinarians to assess the severity of discomfort in dogs objectively. By evaluating a combination of physical indicators, behavioural cues, and owner-reported observations, veterinarians can assign a numerical score that reflects the dog's level of pain. This scoring system can be particularly useful when signs of pain may be subtle, or when trying to determine if new behaviours may be related to pain. By incorporating pain scoring into routine veterinary examinations, pet owners can play an active role in monitoring their dog's well-being and ensuring that any signs of discomfort are promptly addressed. There are several validated pain scores available online - we use an adapted version of the Canine Brief Pain Inventory (click image to download).
Conclusion
The correlation between dog aggression and pain underscores the importance of proactive veterinary care, attentive observation, and compassionate understanding of canine behaviour. By recognizing and addressing subtle signs of pain in dogs, owners can enhance their pet's quality of life, promote their well-being, and foster a trusting and harmonious relationship. Collaboration between veterinarians, behaviourists, trainers, and dog owners is essential in identifying the root cause of aggression and implementing tailored interventions to alleviate pain and improve the overall welfare of our beloved canine companions. Together, we can ensure that dogs receive the care and support they need to thrive and live happy, pain-free lives.
