Dog Pain Signs: 17 Subtle Signals Owners Miss

A recent study has revealed that people frequently miss subtle indicators of pain in dogs, often attributing them to stress or normal behavioral variations. Scientists are urging dog owners to be more attentive to changes in their canine companions’ behavior, as new research highlights 17 key signs of discomfort.

Understanding the Research

The study, based on responses from 647 participants – including 530 dog owners and 117 non-dog owners – investigated how accurately individuals can recognize pain-related behaviors in dogs. Participants completed an online questionnaire, evaluating 17 specific behavioral signs and assessing three case scenarios involving dogs with different conditions.

The 17 Signs of Pain in Dogs

Researchers identified 17 key signs that may indicate a dog is experiencing pain. These include:

  • Change in personality
  • Hesitant paw lifting
  • Fluctuating mood
  • Reduced play
  • Turning the head or body away
  • Freezing
  • Licking surfaces
  • Lip or nose licking
  • Air sniffing
  • Increased blinking
  • Increased grooming
  • Increased scratching
  • Coat changes
  • Changed look
  • Reduced activity
  • Withdrawal or reduced sociability

While some of these signs are more obvious, the study found that many are not widely recognized as indicators of pain.

Recognizing Obvious vs. Subtle Signs

Participants most readily associated “change in personality,” “hesitant paw lifting,” “fluctuating mood,” and “reduced play” with discomfort. These behaviors are typically more noticeable and easier to interpret. However, more subtle behaviors – such as “nose licking,” “yawning,” and “air sniffing” – were consistently underestimated as signals of pain.

Dog Ownership Doesn't Guarantee Recognition

Surprisingly, the study discovered that dog ownership doesn’t automatically improve a person’s ability to detect these quieter pain signals. While dog owners were slightly better at identifying clear, movement-related pain like limping, they showed no significant advantage over non-dog owners in recognizing more nuanced behavioral changes.

In some instances, non-dog owners were even more likely to link behaviors like “turning the head or body away” and “freezing” to pain, potentially because dog owners are accustomed to interpreting these actions as signs of fear or anxiety.

Real-Life Scenario Testing

The research also tested participants’ responses to realistic scenarios. In a case involving obvious pain linked to movement, most participants correctly identified the pain. Dog owners performed slightly better, but both groups demonstrated good overall accuracy.

However, a scenario featuring subtle signs – such as restlessness at night, increased attachment, shadowing family members, and shorter walks – proved much more challenging. Only about half of the participants recognized pain as a likely explanation, with no significant difference between dog owners and non-dog owners.

The Role of Experience

Participants who had personally experienced pain or whose dogs had previously suffered a painful condition were more likely to correctly identify subtle signs. This suggests that firsthand experience can increase sensitivity to behavioral changes associated with discomfort.

Implications for Welfare and Safety

The findings have important implications for both animal welfare and public safety. Pain can make dogs more unpredictable and potentially increase the risk of aggression. Missing early warning signs can make interactions with dogs – even familiar ones – more dangerous.

Researchers emphasize that many early indicators of pain are easily overlooked. Small changes, such as increased grooming, blinking, or behavioral shifts, may signal discomfort long before more obvious symptoms appear. With rising dog ownership, the study underscores the critical need for improved education regarding canine behavior. Recognizing both obvious and subtle signs of pain can lead to earlier intervention, improved welfare, and safer interactions between dogs and humans.
