If your pet is limping, hiding, refusing to eat, whining, or breathing heavily, they may be in pain and could need urgent veterinary care. Some symptoms, like difficulty breathing, collapse, or a swollen abdomen, mean you should go to a vet clinic in Mississauga immediately, without waiting for a regular appointment. This guide breaks down exactly how to recognize pain in dogs and cats, and how to tell the difference between something that can wait and something that can’t.
What Are the Signs of Pain in Dogs and Cats?
Pets can’t tell us in words when something hurts, so they show it through behavior. Watch for:
- Limping or reluctance to move, jump, or climb stairs
- Whining, growling, or unusual vocalizing
- Hiding or avoiding contact with family members
- Increased aggression or irritability when touched
- Loss of appetite or refusing water
- Excessive licking or chewing at one area of the body
- Restlessness, pacing, or inability to get comfortable
- Panting, shallow breathing, or a hunched posture
- Shaking or trembling
Cats in particular are experts at masking pain, so even subtle changes, like sleeping more than usual or avoiding the litter box, are worth taking seriously.
Common Causes of Sudden Pain in Pets
Sudden pain can come from a wide range of issues, including:
- Injuries from falls, rough play, or accidents
- Dental disease, including abscessed or fractured teeth
- Gastrointestinal problems such as an upset stomach or blockage
- Arthritis flare-ups, especially in senior pets
- Ingested foreign objects or toxic substances
Some of these are manageable with a scheduled visit. Others require immediate attention, and the key is knowing which is which.
Urgent vs. Non-Urgent Symptoms
| Can Wait for a Regular Appointment | Go to a Vet Immediately |
| Mild limping that improves with rest | Sudden collapse or inability to stand |
| Slightly reduced appetite for a day | Difficulty breathing or blue-tinged gums |
| Occasional scratching or licking | Bloated, hard, or distended abdomen |
| Mild lethargy after a long walk | Straining to urinate with no output |
| Small, healing scrapes or cuts | Uncontrolled bleeding or deep wounds |
| Minor changes in stool | Seizures or sudden disorientation |
| One-off vomiting with normal energy | Repeated vomiting combined with weakness |
If you’re ever unsure which column your pet’s symptoms fall into, it’s always safer to call the clinic and ask.
Emergency Red Flags: Go to the Vet Right Away
Treat the following as true emergencies and head to a vet clinic immediately:
- Difficulty breathing or gasping for air
- Collapse or sudden inability to stand or walk
- Seizures, tremors, or loss of consciousness
- A bloated, swollen, or hard abdomen
- Inability to urinate or defecate, especially in male cats
- Uncontrolled bleeding or a deep wound
- Suspected poisoning or ingestion of a toxic substance
- Trauma from a car accident, fall, or fight with another animal
These situations can become life-threatening within hours, so don’t wait to “see if it gets better.”
What to Do Before You Arrive at the Clinic
- Stay calm. Pets pick up on your stress, which can make handling harder.
- Avoid moving an injured pet unnecessarily, especially if you suspect a broken bone or spinal injury. Use a flat surface or carrier to transport them safely.
- Call ahead so the clinic can prepare for your arrival, particularly for a suspected emergency.
- Never give human medication (like ibuprofen or acetaminophen), as many common over-the-counter drugs are toxic to pets.
- Bring any relevant details, such as what your pet ate, when symptoms started, or if there was a recent injury.

Frequently Asked Questions
How do I know if my dog is in serious pain?
Signs of serious pain in dogs include limping, whining, reluctance to move, loss of appetite, and changes in breathing or posture. If these symptoms are severe or sudden, treat it as urgent and contact a vet right away.
Can cats hide pain even when it’s severe?
Yes. Cats are known for masking pain as a survival instinct. Subtle signs like hiding, reduced grooming, or changes in litter box habits can indicate significant pain, even without obvious symptoms.
What should I do if my pet ate something toxic?
Call your vet clinic or an animal poison control hotline immediately. Don’t wait for symptoms to appear, and don’t induce vomiting unless a professional instructs you to.
Is a limping dog an emergency?
It depends on severity. Mild limping that improves with rest can often wait for a regular appointment. Sudden, severe limping, an inability to bear weight, or an obviously deformed limb should be seen immediately.
What are the clinic hours for urgent visits?
Erin Centre Animal Hospital is open Monday to Friday from 10:00 am to 7:00 pm and Saturday from 10:00 am to 3:00 pm. For after-hours emergencies, contact your nearest 24-hour emergency animal hospital.
