Pain Management

Pain Management for Dogs, Cats, and Other Pets

Veterinary Diagnostic Services at Southern Ocean Animal Hospital

TL;DR: Quick Summary

Pain management is the careful use of medications, therapies, diagnostics, and home-care changes to reduce discomfort and improve quality of life for pets.

Dogs, cats, and other animals can feel pain from many causes, including:

Arthritis
Injury
Surgery
Dental disease
Ear infections
Back or neck problems
Cancer
Skin wounds
Pancreatitis
Urinary problems
Trauma
Chronic illness
Nerve pain

Pain management is not just about making pets “more comfortable.” It helps them heal, move better, rest better, eat better, and enjoy daily life.

At Southern Ocean Animal Hospital, Dr. Dan and the team use pain assessment as part of a complete diagnostic plan. The goal is to find the source of pain, treat the underlying problem, and choose safe pain relief based on your pet’s species, age, health history, lab results, and condition.

Important: Never give human pain medication to a pet unless a veterinarian specifically tells you to. Common human medications such as ibuprofen, naproxen, aspirin, and acetaminophen can be dangerous or even life-threatening for dogs and cats.

ELI5: Pain Management Explained Simply

Imagine your pet has pain, but they cannot say:

“My back hurts.”

“My tooth hurts.”

“My belly hurts.”

“My joints ache when I stand up.”

Instead, pets show pain through behavior. They may hide, limp, pant, stop jumping, growl, avoid stairs, sleep more, eat less, or act “not like themselves.”

Pain management is how Dr. Dan helps answer three big questions:

Where does it hurt?
Why does it hurt?
What can we do safely to help?

Sometimes pain relief means medication. Sometimes it means surgery, dental care, laser therapy, weight management, rest, exercise changes, or treating an infection.

The best pain plan is not one-size-fits-all. It is built around your pet.

Introduction

Pain is one of the most important health concerns in veterinary medicine. It affects how pets move, sleep, eat, heal, interact, and enjoy life. Pain can be obvious, like a dog crying after an injury. It can also be subtle, like a cat who no longer jumps onto the couch or a senior dog who hesitates before climbing stairs.

Many pets hide pain by instinct. This is especially true for cats, rabbits, birds, reptiles, and other animals that naturally avoid showing weakness. A pet may continue eating, wagging, purring, or greeting the family while still experiencing significant discomfort.

That is why pain management begins with pain recognition.

At Southern Ocean Animal Hospital, Dr. Dan and the team evaluate pain as part of a complete diagnostic picture. Pain is not treated as “just part of getting older” or something pets should be expected to tolerate. Whether your pet is recovering from surgery, dealing with arthritis, experiencing dental pain, or showing signs of sudden illness, identifying and managing pain is an essential part of compassionate care.

Pain management may involve:

Physical examination
Orthopedic evaluation
Neurologic evaluation
Dental examination
Bloodwork
Digital radiology
Dental radiology
Ultrasonography
Cytology
Blood pressure monitoring
Emergency lab workups
Medications
Local anesthetics
Injectable therapies
Lifestyle changes
Weight management
Laser therapy
Rehabilitation guidance
Follow-up monitoring

The goal is always to reduce suffering, protect safety, and improve quality of life.

Key Ideas for Pet Owners

Pets feel pain, but they may not show it clearly.
Pain can be acute, chronic, mild, severe, visible, or hidden.
Pain management starts with finding the cause.
Dogs and cats process medications differently, so pain medicine must be species-specific.
Human pain relievers can be toxic to pets.
Arthritis pain is common in senior pets, but younger pets can also experience pain.
Dental disease is a major source of hidden pain.
Cats often show pain through behavior changes rather than crying or limping.
Emergency pain may require lab work, imaging, oxygen therapy, fluids, or surgery.
Long-term pain plans often combine medication, weight management, home changes, and monitoring.
Good pain control helps pets heal better and live more comfortably.

What Is Veterinary Pain Management?

Veterinary pain management is the medical process of identifying, treating, and monitoring pain in animals.

It includes two major parts:

Diagnosis: finding what is causing the pain.
Treatment: reducing pain safely while addressing the underlying condition.

Pain management may be needed for:

Short-term pain after surgery
Injury-related pain
Dental pain
Ear pain
Skin wounds
Back or neck pain
Arthritis
Cancer pain
Abdominal pain
Nerve pain
Chronic disease pain
Emergency trauma

The right treatment depends on the source and severity of pain.

For example, a dog with a torn nail needs a different plan than a cat with arthritis, a rabbit with dental disease, or a dog recovering from abdominal surgery.

Acute Pain vs. Chronic Pain

Pain is often grouped into two main types: acute and chronic.

Type of Pain	What It Means	Examples
Acute Pain	Sudden pain from injury, surgery, infection, or illness	Broken nail, wound, surgery, ear infection, trauma
Chronic Pain	Long-term pain that continues over weeks, months, or years	Arthritis, spinal disease, cancer, chronic dental disease

Acute pain is often easier to notice because it comes on suddenly.

Chronic pain can be harder to recognize because pets slowly change their behavior over time. A pet owner may think, “He’s just getting older,” when the real issue is untreated pain.

Common Causes of Pain in Pets

Pets can experience pain from many conditions.

Orthopedic Pain

This includes pain involving bones, joints, muscles, and ligaments.

Common causes include:

Arthritis
Hip dysplasia
Elbow dysplasia
Knee injuries
Fractures
Sprains
Muscle strains
Luxating patella
Torn cruciate ligament

Dental Pain

Dental pain is one of the most common hidden sources of discomfort in dogs and cats.

Causes include:

Periodontal disease
Tooth root abscesses
Broken teeth
Resorptive lesions in cats
Retained baby teeth
Oral tumors
Gum infection

Pets with dental pain may still eat, especially if they are hungry. Eating does not prove the mouth is pain-free.

Soft Tissue Pain

Soft tissue pain may come from:

Wounds
Abscesses
Burns
Skin infections
Ear infections
Surgical incisions
Inflammation
Bite wounds

Abdominal Pain

Belly pain may be caused by:

Pancreatitis
Foreign body obstruction
Gastrointestinal inflammation
Bladder stones
Urinary obstruction
Liver or gallbladder disease
Internal bleeding
Reproductive emergencies

Neurologic Pain

Nerve-related pain can be intense and difficult to recognize.

Possible causes include:

Intervertebral disc disease
Pinched nerves
Spinal injury
Neck pain
Back pain
Nerve trauma
Certain chronic pain syndromes

Cancer Pain

Cancer may cause pain by pressing on tissues, invading bone, affecting organs, or creating inflammation.

Pain control is an important part of cancer care and quality-of-life support.

Signs Your Pet May Be in Pain

Pain does not always look like crying.

Many pets show pain through subtle behavior changes.

How Dr. Dan Diagnoses Pain

Pain management begins with understanding the cause.

At Southern Ocean Animal Hospital, Dr. Dan may use several steps to determine where the pain is coming from and how serious it is.

Step 1: Listening to the Pet Owner

You know your pet best.

Dr. Dan may ask:

When did the signs start?
Is the pain sudden or gradual?
Is your pet eating normally?
Is your pet limping?
Any vomiting or diarrhea?
Any trouble urinating?
Any falls, rough play, or trauma?
Is your pet hiding or acting withdrawn?
Is your pet sleeping more?
Are stairs, jumping, or walks harder?
Does your pet react when touched?

Small details can be very important.

Step 2: Physical Examination

A full exam may include:

Checking posture
Watching your pet walk
Feeling joints and muscles
Checking the spine
Examining the mouth
Looking at the ears
Checking eyes
Feeling the abdomen
Evaluating hydration
Listening to the heart and lungs
Checking temperature
Looking for swelling, wounds, or infection

Step 3: Pain Scoring

Veterinary teams may use pain scoring tools to evaluate pain more consistently.

Pain scoring may consider:

Body posture
Facial expression
Movement
Response to touch
Appetite
Behavior
Vocalization
Comfort at rest

Step 4: Diagnostic Testing

If the cause is not obvious, Dr. Dan may recommend diagnostics such as:

Bloodwork
Urinalysis
Digital radiology
Dental radiology
Ultrasound
Cytology
Ear exam or video otoscopy
Tonometry for eye pain
Blood pressure monitoring
Emergency lab workups
Referral imaging when needed

The goal is to treat the pain and the reason for the pain.

Why Emergency Labs May Be Ordered with Pain Management

Pain can be a sign of something more serious happening inside the body.

Emergency lab work may be ordered when pain is sudden, severe, unexplained, or connected with other concerning symptoms.

Emergency labs may help identify:

Infection
Internal bleeding
Organ stress
Kidney disease
Liver disease
Pancreatitis
Dehydration
Electrolyte imbalance
Toxin exposure
Anemia
Severe inflammation
Blood sugar problems
Clotting problems

Labs may also be needed before certain pain medications are prescribed.

For example:

NSAIDs may not be safe for every pet with kidney, liver, stomach, or dehydration concerns.
A pet in shock may need fluids and stabilization before medication decisions.
A pet with abdominal pain may need bloodwork to check for pancreatitis or organ stress.
A pet needing emergency surgery may need labs before anesthesia.
A senior pet with arthritis may need bloodwork before starting long-term medication.

Pain relief should be safe, not just strong.

Main Types of Pain Relief Medications

Pain medications must be chosen carefully. Dogs, cats, rabbits, birds, reptiles, and other pets all process medications differently.

Never share medications between pets unless your veterinarian specifically instructs you to.

NSAIDs

NSAIDs are non-steroidal anti-inflammatory drugs.

They help reduce inflammation and pain.

They may be used for:

Arthritis
Surgical pain
Soft tissue injury
Joint pain
Dental pain
Some orthopedic conditions

Examples used in veterinary medicine may include carprofen, meloxicam, deracoxib, firocoxib, grapiprant, or robenacoxib depending on the pet and condition.

NSAIDs can be very helpful, but they are not safe for every pet. Dr. Dan may recommend bloodwork before and during long-term NSAID use to monitor kidney and liver values.

Opioids

Opioids are stronger pain-relief medications often used for moderate to severe pain.

They may be used for:

Surgery
Trauma
Severe injury
Cancer pain
Hospitalized patients
Severe acute pain

Examples may include buprenorphine, hydromorphone, fentanyl, or other medications depending on the case.

Opioids are used carefully and under veterinary supervision.

Local Anesthetics

Local anesthetics numb a specific area.

They may be used dur
