Common Signs Your Dog Is in Pain

Many dogs are surprisingly good at hiding discomfort. In the veterinary world, we see it all the time: a dog who still wags their tail, still eats, and still tries to be “good,” even while they hurt. The tricky part is that pain does not always look like crying or limping. Sometimes it looks like your dog is getting older, acting stubborn, or suddenly “not themselves.”

This article will walk you through common, vet-recognized signs of pain in dogs, what they can mean, and what you can do next. If you are unsure, trust your gut. It is always better to check than to wait.

Why dogs hide pain

Many dogs have an instinct to avoid looking vulnerable, even in a safe home. Some dogs also have a high drive to please, so they keep going until the pain is significant. Others are the opposite and show you right away.

Because of this, the most reliable clues are often subtle changes in routine: movement, mood, sleep, appetite, and daily habits.

Common signs of pain

These signs are commonly used in clinical settings and show up in veterinary pain scoring tools such as the Glasgow Composite Measure Pain Scale (short form) and the Colorado State University acute pain scale. One sign alone might not prove pain, but a pattern of changes is a strong clue. Also, some of the signs below can signal illness that is not primarily pain, which is another reason a vet exam matters.

1) Movement changes

• Limping, stiffness, or “warming up” after rest
• Reluctance to jump onto the bed, sofa, or into the car
• Slower on walks, stopping more often, or lagging behind
• Difficulty with stairs or hesitation at the first step
• Restlessness, pacing, or repeatedly getting up and down
• New vocalizing with movement (whining, yelping, or a sudden grunt when standing)

What it can mean: arthritis, muscle strain, ligament injury (like a CCL tear), back pain, hip dysplasia, paw injuries, or nail problems.

2) Posture and body language

• Hunched back or tucked abdomen
• Head held low or neck stiff, especially when turning
• Weight shifted off one leg, or sitting “crooked”
• Tucked tail or less tail movement than usual
• Ears pinned back, tense face, or a “worried” look

Many owners miss face changes, but they can be incredibly telling. A painful dog may have tight lips, a furrowed brow, squinty eyes, or a hard stare.

3) Licking, chewing, or guarding

• Constant licking at paws, joints, belly, or a specific spot
• Chewing at hips or tail base
• Flinching when touched in one area
• Pulling away or hiding when you reach toward them
• Guarding a body part (freezing, growling, or turning their head toward your hand)

What it can mean: paw pad injury, foxtail or foreign body, arthritis, anal gland discomfort, skin infection, hot spot, dental pain (some dogs rub their face), or abdominal pain.

4) Appetite, drinking, and swallowing

• Eating less or dropping food
• Chewing on one side or eating slower
• Sudden picky behavior, especially with kibble
• More drooling than normal

These can be classic for dental pain, mouth injuries, nausea, or throat issues. Dental disease is one of the most common hidden pain sources seen in practice.

5) Dental and mouth pain clues

Some dogs will still eat even with significant oral pain, so look for the small tells.

• Bad breath that is new or worsening
• Pawing at the mouth or rubbing the face on furniture
• Facial swelling (especially under the eye)
• Bleeding gums or a sudden dislike of chew toys

6) Eye pain clues

• Squinting or holding an eye partly closed
• Excess tearing or discharge
• Redness or a cloudy-looking eye
• Pawing at the eye or rubbing the face on the floor

Eye pain can escalate quickly. If your dog is squinting or you suspect an eye injury, treat it as urgent.

7) Mood and behavior changes

• Irritability or “snapping,” especially when approached or touched
• Clinginess or wanting constant contact
• Withdrawal, hiding, or avoiding the family
• Less interest in play or favorite activities
• Sudden anxiety, especially at night

Pain can look like a behavior problem. If your sweet dog becomes grumpy, do not assume it is “dominance” or “attitude.” Assume discomfort until proven otherwise.

8) Sleep, breathing, and comfort

• Trouble settling or waking often
• Sleeping in unusual places or positions
• Panting at rest when it is not hot and they are not excited
• Shaking or trembling

Panting can be pain-related, but it can also be heart, lung, stress, hormonal issues (like Cushing’s), or fever. Context matters, and a vet exam is important.

9) Bathroom habit changes

• Straining to pee or frequent small pees
• Accidents in the house from reluctance to move or get outside
• Straining to poop, crying, or constipation
• Taking a long time to posture to urinate or defecate

What it can mean: urinary tract issues, bladder stones, spinal pain, arthritis, anal gland issues, GI discomfort, or dehydration.

Pain by life stage

Puppies and young dogs

• Injuries from play, sprains, broken nails
• Panosteitis or other developmental orthopedic conditions (especially in large breeds)
• Foreign bodies in paws or mouth

Adult dogs

• Dental disease
• Ear infections (often painful)
• GI pain, pancreatitis, or dietary triggers
• Cruciate ligament (CCL) injuries

Senior dogs

• Arthritis and chronic joint inflammation
• Spinal disease
• Dental pain
• Masses or cancer-related discomfort

When it is an emergency

Please seek emergency care if you notice any of the following:

• Bloated or hard abdomen, repeated unproductive retching, restlessness that looks like panic, or sudden collapse (possible bloat)
• Not able to stand, dragging legs, sudden severe weakness, or suspected spinal injury
• Crying out in pain and cannot get comfortable
• Labored breathing, blue or pale gums
• Inability to urinate or signs of urinary blockage
• Uncontrolled bleeding, seizures, or severe disorientation
• Ingested toxins or possible foreign body (string, socks, corn cobs, or cooked bones)
• Eye injury or sudden squinting with redness or cloudiness

If you are unsure, call an emergency clinic. Describe the symptoms plainly and ask if they need to be seen now.

What to do next

1) Track what you see

If your dog’s signs are mild and stable, short notes can help your veterinarian tremendously. If symptoms are worsening, your dog is very lethargic, not eating, vomiting, has diarrhea, or seems significantly uncomfortable, do not wait 48 hours.

• When did it start?
• What makes it worse or better?
• Is there limping, panting, trembling, or licking?
• Any changes in appetite, stool, or urination?

Tip: Take a short video of your dog walking, sitting, and standing. Many dogs “act normal” at the clinic, and videos are gold.

2) Book a vet exam

Pain is a symptom, not a diagnosis. Your vet may recommend an orthopedic exam, dental exam, bloodwork, urinalysis, X-rays, or an ultrasound depending on the signs.

3) Do not give human pain meds

This is so important. Many over-the-counter human medications can be toxic to dogs, including ibuprofen and naproxen. Aspirin and acetaminophen can also be dangerous depending on the dose and the dog’s health status. Do not try to calculate dosing at home. Only give medications prescribed or explicitly approved by your veterinarian.

4) What not to do

• Do not force exercise or “walk it off.”
• Do not manipulate a painful limb, neck, or back if injury is possible.
• Do not delay care if you see red-flag signs, even if your dog has good moments.

5) Make home more comfortable

• Limit jumping: use ramps or block access to furniture
• Use rugs for traction on slick floors
• Offer a supportive bed in a quiet area
• Gentle, short potty breaks instead of long walks
• Keep nails trimmed to reduce joint stress

Vet-backed pain options

Treatment depends on the cause, but these are common, research-supported options:

• Veterinary pain medications (for example, NSAIDs formulated for dogs when appropriate, plus other pain-modulating medications if needed)
• Weight management for arthritis and joint disease, even small weight loss can reduce joint load
• Physical therapy and controlled exercise plans
• Joint-support diets and omega-3 fatty acids (EPA and DHA) for inflammatory support
• Dental treatment for oral pain
• Cold or heat therapy guided by your veterinarian
• Acupuncture or laser therapy as adjunct options for some dogs

If your dog has chronic pain, ask your vet about a multi-modal plan. In practice, this often works better than relying on one single tool.

Help your dog feel safe

Pain can make dogs anxious. You can support them with calm routines and gentle handling.

• Approach slowly and avoid sudden hugs around sore areas.
• Let your dog choose contact. Sit near them and offer a hand rather than reaching over their head.
• Keep schedules consistent for meals, potty breaks, and bedtime.

If your dog’s personality changes, treat it like a medical clue. Behavior is often the first sign that something hurts.

The bottom line

You do not need to “wait for it to get worse” to take pain seriously. Subtle signs like slower movement, panting at rest, avoiding stairs, squinting, or sudden grumpiness are often your dog’s way of asking for help.

If you take one step today, let it be this: write down the changes you see and schedule an exam. With the right diagnosis and a thoughtful plan, many dogs feel better faster than you might expect.
