How to Tell if Your Pet Is in Pain: A Complete Guide for Pet Parents

Our pets can’t tell us when something hurts. They can’t point to where it aches or describe the sharpness of a twinge. Instead, they rely on us to notice the subtle — and sometimes not-so-subtle — signs that something is wrong. Recognizing pain in pets is one of the most important skills a pet parent can develop, because early detection often leads to better outcomes. Whether you share your home with a dog, a cat, or both, this guide will help you understand the signs of pain and know when it’s time to seek veterinary help.

Why Pets Hide Pain

In the wild, showing weakness or pain makes an animal a target for predators. This survival instinct is deeply ingrained, and it doesn’t disappear just because our pets live safely in our homes. Dogs and cats will often mask their pain for as long as possible, which means by the time you notice something is wrong, the underlying condition may have been developing for weeks or even months.

This is why it’s so important to know your pet’s normal behavior. Any deviation — however small — could be a signal that your pet is hurting.

Signs of Pain in Dogs

Dogs tend to show pain more overtly than cats, but the signs can still be easy to miss if you’re not paying attention. Here are the key indicators to watch for:

Physical Signs

• Limping or favoring a leg — One of the most obvious signs of orthopedic pain
• Difficulty standing up or lying down — Common in dogs with arthritis or hip dysplasia
• Reluctance to jump or climb stairs — May indicate joint or back pain
• Swelling or heat — Around joints, wounds, or any body part
• Excessive panting — Especially at rest or in cool environments
• Restlessness — Pacing, inability to get comfortable, frequently shifting positions
• Changed posture — Hunched back, head lowered, or a rigid stance

Behavioral Signs

• Decreased appetite — A dog that suddenly loses interest in food may be in pain
• Withdrawal or hiding — Seeking isolation instead of companionship
• Increased aggression — Growling, snapping, or biting when touched, especially near the painful area
• Excessive licking or chewing — Particularly focused on one area of the body
• Whining, whimpering, or howling — Vocalizations that are unusual for your dog
• Loss of interest in play or walks — A previously active dog becoming sedentary
• Changes in sleep patterns — Sleeping more or struggling to settle

Signs of Pain in Cats

Cats are particularly adept at hiding pain, which makes detection even more challenging. You need to be a careful observer of your cat’s daily habits to catch the subtle changes that signal discomfort.

Physical Signs

• Crouching or hunched posture — A cat in pain often sits with all four paws tucked under the body
• Squinting or half-closed eyes — A subtle but reliable sign of discomfort
• Flattened ears — Ears rotated outward or pressed against the head
• Tail tucked close to the body — Instead of held upright in a relaxed position
• Limping or stiffness — Especially noticeable after resting
• Poor grooming — A normally meticulous cat with a matted or dull coat
• Overgrooming — Excessively licking one area, sometimes to the point of hair loss

Behavioral Signs

• Hiding more than usual — Retreating to closets, under beds, or other secluded spots
• Decreased appetite — One of the earliest and most common signs
• Reduced activity — No longer jumping onto favorite perches or playing
• Changes in litter box habits — Urinating or defecating outside the box may indicate pain
• Irritability or aggression — Hissing, swatting, or biting when handled
• Excessive vocalization — Unusual meowing, especially in senior cats with cognitive decline
• Avoiding being picked up — Resisting handling that was previously accepted

Common Sources of Pain in Pets

Understanding what commonly causes pain can help you stay vigilant. Some of the most frequent sources include:

Acute Pain

• Injuries — Cuts, sprains, fractures, or trauma from accidents
• Surgical recovery — Post-operative pain after spay/neuter, dental work, or orthopedic surgery
• Dental disease — Fractured teeth, gum infections, or oral tumors
• Infections — Ear infections, urinary tract infections, abscesses
• Gastrointestinal issues — Pancreatitis, bowel obstructions, or foreign body ingestion

Chronic Pain

• Osteoarthritis — The most common source of chronic pain in both dogs and cats, especially seniors
• Cancer — Bone cancer, soft tissue tumors, and other malignancies
• Back and spine problems — Intervertebral disc disease, spondylosis
• Chronic inflammation — Inflammatory bowel disease, stomatitis in cats
• Neuropathic pain — Nerve damage or compression

The Pain Assessment Tools Vets Use

Veterinarians use validated pain scales to assess discomfort in animals. These include the Glasgow Composite Pain Scale for dogs and the Feline Grimace Scale for cats. The Feline Grimace Scale, in particular, has revolutionized cat pain assessment by evaluating five facial expressions: ear position, orbital tightening, muzzle tension, whisker position, and head position above the shoulder line.

While these tools are designed for professional use, the principles behind them can help you at home. Pay attention to your pet’s facial expressions, body language, and overall demeanor. If something looks different from their normal appearance, it’s worth investigating.

What to Do If You Think Your Pet Is in Pain

1. Don’t wait — Pain rarely resolves on its own, and early intervention leads to better outcomes
2. Don’t give human medication — Ibuprofen, acetaminophen, and aspirin can be toxic to pets. Only use medications prescribed by your vet
3. Document the signs — Take notes or videos of the behaviors that concern you to share with your vet
4. Schedule a vet visit — Describe what you’ve observed in detail, including when the changes started
5. Keep your pet comfortable — Provide a soft bed, easy access to food and water, and a quiet environment
6. Limit activity — Restrict jumping, running, and rough play until you have a diagnosis

Managing Chronic Pain in Pets

If your pet is diagnosed with a chronic pain condition, there are many management strategies available:

• Prescription medications — NSAIDs, gabapentin, tramadol, and newer therapies like Librela (for dogs) or Solensia (for cats)
• Joint supplements — Glucosamine, chondroitin, and omega-3 fatty acids
• Weight management — Reducing excess weight significantly decreases stress on painful joints
• Physical therapy — Hydrotherapy, laser therapy, acupuncture, and massage
• Environmental modifications — Ramps, orthopedic beds, raised food bowls, and non-slip flooring
• Diet changes — Prescription joint diets or anti-inflammatory nutrition plans

Trust Your Instincts

As a pet parent, you know your animal better than anyone. If something feels off — even if you can’t pinpoint exactly what — trust that instinct. Many veterinarians report that the most reliable indicator of pain is the owner’s observation that “something is just not right.” Never feel like you’re overreacting by seeking veterinary advice. When it comes to pain, it’s always better to be safe than sorry.
