Is Your Dog in Pain? 15 Subtle Signs Every Pet Owner Should Know.

By Steve Mehler, DVM, DACVS

When most people think of a dog in pain, they picture obvious signs like crying, limping, or refusing to walk.

But here's something that surprises many pet owners:

Most dogs don't show pain that way.

Dogs evolved from wild ancestors that survived by hiding weakness. An injured animal was more likely to become prey or lose its place in the social hierarchy. Although our pets sleep on couches instead of hunting for food, that instinct remains deeply ingrained.

As a veterinarian, one of the most common things I hear is:

"I had no idea he was hurting."

The reality is that chronic pain often develops so gradually that both dogs and owners adapt to it. The changes become the "new normal."

Learning to recognize those subtle signs can dramatically improve your dog's quality of life.

Why Dogs Hide Pain

Pain isn't just a physical sensation.

It's an emotional and behavioral experience that affects nearly every aspect of a dog's daily life.

Instead of yelping or crying, many dogs simply change their behavior.

They may:

• Move less

• Sleep more

• Play less

• Become quieter

• Avoid stairs

• Interact differently with family members

These changes are often mistaken for "just getting older."

Many aren't.

15 Subtle Signs Your Dog May Be in Pain

1. They Don't Jump Into the Car Anymore

One of the earliest signs of arthritis is hesitation.

Instead of jumping confidently, your dog may:

• Pause

• Look uncertain

• Need encouragement

• Ask for help

• Walk away altogether

This isn't stubbornness.

It's often discomfort.

2. They're Slower on Walks

If your dog used to lead the way but now lags behind, stops frequently, or wants to head home early, pain may be limiting their activity.

Many owners simply assume their dog is slowing down with age.

Sometimes they are.

Sometimes they're hurting.

3. They Sleep More

Pain is exhausting.

Dogs experiencing chronic discomfort often spend more time resting—not because they're lazy, but because movement hurts.

4. They Lick One Spot Repeatedly

Persistent licking of:

• wrists

• elbows

• hips

• knees

• paws

may indicate underlying joint pain or soft tissue injury.

Some dogs lick until the hair disappears.

5. Changes in Personality

Pain changes behavior.

Friendly dogs may become withdrawn.

Independent dogs may suddenly become clingy.

Calm dogs may become irritable.

These personality shifts deserve attention.

6. Difficulty Standing Up

Watch your dog after they've been lying down.

Do they:

• Rock forward?

• Push with their front legs?

• Struggle briefly before standing?

These are common signs of arthritis and muscle weakness.

7. Muscle Loss

Pain causes decreased use of affected limbs.

Over time, muscles shrink.

Owners often notice one rear leg becoming thinner than the other.

Muscle loss is never a normal part of aging.

It's usually a sign that something isn't being used properly.

8. They Stop Playing

Dogs naturally enjoy activities they find rewarding.

When play suddenly disappears, pain should always be considered.

Especially if your dog still seems interested—but quits quickly.

9. Changes in Grooming

Some painful dogs stop grooming altogether.

Others over-groom painful areas.

Either extreme can signal discomfort.

10. Changes in Appetite

Pain doesn't just affect movement.

It can reduce appetite, especially when chewing becomes uncomfortable because of dental disease or jaw pain.

11. Reluctance to Use Stairs

Stairs place tremendous stress on:

• hips

• knees

• elbows

• shoulders

• spine

Dogs with arthritis often hesitate long before they begin limping.

12. Changes in Sleeping Position

Some painful dogs:

• can't get comfortable

• change positions frequently

• sleep sitting up

• avoid lying on one side

Small changes often tell a big story.

13. Panting Without Exercise

Excessive panting can have many causes, including:

• pain

• anxiety

• heart disease

• respiratory disease

• heat

If your dog pants while resting, it's worth discussing with your veterinarian.

14. Less Interest in Family

Many painful dogs quietly withdraw.

They may no longer greet you at the door.

They may stop following you from room to room.

Some owners mistakenly think their dog has become "less affectionate."

Sometimes they're simply uncomfortable.

15. They Just Don't Look Happy

This is the hardest sign to describe—but experienced veterinarians notice it immediately.

The bright expression fades.

The eyes look tired.

Movement loses enthusiasm.

Owners often say,

"He's just not himself."

Trust that instinct.

Pain Doesn't Always Mean Limping

One of the biggest misconceptions in veterinary medicine is that pain equals limping.

Many painful dogs never limp.

Instead, they compensate.

They shift weight.

They shorten their stride.

They move differently.

By the time limping develops, the problem has often existed for months.

What Causes Pain?

Common causes include:

• Osteoarthritis

• Cranial cruciate ligament disease

• Hip dysplasia

• Elbow dysplasia

• Dental disease

• Intervertebral disc disease

• Muscle injuries

• Cancer

• Ear infections

• Nail injuries

The earlier these conditions are identified, the more treatment options are available.

What Should You Do?

If you notice several of these signs, schedule a veterinary examination.

Your veterinarian may recommend:

• Orthopedic evaluation

• Pain assessment

• Radiographs (X-rays)

• Blood work

• Weight management

• Physical rehabilitation

• Joint supplements

• Anti-inflammatory medications

• Other pain-control strategies tailored to your dog's condition

Early intervention often helps dogs regain mobility, confidence, and joy.

The Bottom Line

Dogs are incredibly resilient.

They don't complain.

They don't tell us where it hurts.

Instead, they whisper through subtle changes in behavior.

The challenge is learning to listen.

One of the greatest gifts we can give our dogs isn't simply helping them live longer—it's recognizing discomfort early enough that they can continue enjoying the life they've always loved.

Because growing older doesn't have to mean living in pain.
