🐾 Signs a Dog Is in Pain: What Every Owner Should Know

Emergency Vet Helpline & 24/7 UK Clinics

Dogs, unable to verbalise discomfort, often exhibit subtle—or dramatic—signs when in pain. Recognising “signs a dog is in pain” early can make all the difference in prompt treatment and better outcomes. Find our list of top vets in London here.

🐶 1. Common Behavioural Signs a Dog Is in Pain

Identifying behavioural signs a dog is in pain can be tricky, but there are key changes that often indicate discomfort. Always pay attention to subtle shifts in your dog’s usual behaviour.

• Loss of Appetite or Refusing Treats
  One of the first dog pain symptoms is a sudden loss of interest in food. If your dog usually eats enthusiastically but suddenly refuses meals or treats, it could be a sign of internal discomfort, nausea, or dental issues.

• Clinginess or Withdrawal
  Some dogs become excessively needy when in pain, constantly seeking reassurance. Others may hide in unusual places, avoid interaction, or sleep more than usual.

• Limping, Stiffness or Slow Movement
  Pain often affects mobility. Look out for limping, stiffness, a hunched posture, or reluctance to get up, lie down, climb stairs, or jump onto furniture.

• Excessive Vocalisation
  Dogs in pain may whine, yelp, growl, or bark excessively—especially when touched or moved. This is one of the more vocal signs a dog is in pain and should not be ignored.

• Increased Irritability or Aggression
  Even the gentlest dogs may growl, snap, or act out when hurting. A normally calm dog that suddenly becomes aggressive could be trying to protect a painful area.

• Decreased Energy or Lethargy
  A major warning sign your dog is in pain is reduced playfulness or enthusiasm for walks. If your pet seems depressed or disinterested in things they usually enjoy, pain could be the cause.

• Restlessness or Inability to Settle
  Pacing, shifting positions constantly, or refusing to lie down comfortably can indicate discomfort, especially with abdominal pain or joint problems.

🩺 2. Physical & Clinical Signs of Dog Pain

In addition to behavioural cues, physical signs a dog is in pain are important to monitor. These can offer a clearer picture of where the issue might lie.

• Panting or Rapid Breathing (Not Heat-Related)
  Dogs often pant when in pain, even when resting. Shallow, fast breathing can also indicate chest or abdominal discomfort.

• Excessive Licking, Biting, or Chewing
  Constant attention to a specific spot—especially a paw, leg, or joint—may signal injury, inflammation, or infection. It’s also common in post-operative discomfort.

• Shaking or Trembling
  Not just a sign of cold—trembling in dogs can be due to pain, anxiety, or poisoning. Look for this symptom if other issues are also present.

• Swelling, Heat, or Tenderness in Limbs or Joints
  Arthritis, sprains, or injuries often cause inflammation. If you feel unusual heat or see puffiness, it's a strong indicator of pain.

• Open Wounds, Bleeding, or Discharge
  External injuries are clear dog pain symptoms. Wounds may also lead to secondary infections, causing more internal pain than is visible.

• Changes in Bathroom Habits
  Straining, constipation, or accidents indoors could point to pain in the gastrointestinal or urinary systems—especially in previously house-trained pets.

• Neglected Grooming or Dirty Appearance
  Dogs in pain may not groom themselves properly. You may notice dull, greasy fur, matting, or a foul odour, especially if licking a sore area excessively.

• Visible Changes in Eyes or Face
  Squinting, eye redness, or drooping can signal facial or dental pain. Dogs may also hold their ears back or look generally distressed.

🚨 3. Red-Flag Symptoms That Require Immediate Help

When the pain is critical or life-threatening, quick action is essential. These emergency signs a dog is in pain require immediate veterinary attention.

• Collapse or Inability to Stand
  This is a serious indicator, often related to internal bleeding, poisoning, heatstroke, or neurological trauma.

• Seizures or Convulsions
  Seizures can be caused by brain injuries, toxins, or severe infections. A dog that experiences a seizure needs urgent evaluation.

• Severe Breathing Difficulties or Choking
  Laboured breathing, blue gums, or wheezing may indicate blocked airways, heart failure, or allergic reactions.

• Vomiting Blood or Passing Black Stools
  These signs point to internal bleeding, which can be fatal if not addressed quickly. Bloody urine is also a red flag.

• Major Trauma (e.g., Hit by Car)
  Even if your dog seems “fine,” internal injuries can take time to show. Immediate vet assessment is vital after any accident.

• Bloat (Gastric Dilatation-Volvulus)
  If your dog has a swollen belly, is drooling excessively, or trying to vomit without success, they could be suffering from bloat—a fatal emergency that requires surgery.

• Extreme Restlessness or Crying in Pain
  Prolonged, high-pitched crying, inability to get comfortable, or frantic pacing often signals intense distress. Don’t wait—get help.
