Can Dogs Have Paracetamol? Looking After Your Dog

No — you should never give your dog paracetamol (also known as acetaminophen) unless specifically prescribed by a vet. While paracetamol is a common over-the-counter painkiller for humans, it can be extremely dangerous — even fatal — to dogs if given incorrectly.

Paracetamol affects dogs differently than it does humans, and what seems like a small, harmless dose for you could cause serious liver damage, blood cell problems, or death in a dog.

Why Is Paracetamol Dangerous for Dogs?

Dogs are much more sensitive to paracetamol than humans. Even small amounts can cause:

• Liver failure

• Internal bleeding

• Low oxygen levels in the blood (caused by damage to red blood cells)

• Organ damage

Symptoms of paracetamol poisoning in dogs can include vomiting, drooling, difficulty breathing, swollen face or paws, dark gums, or signs of lethargy and collapse.

Can Vets Prescribe Paracetamol?

Yes — in very specific cases, a vet may prescribe a carefully calculated dog-safe dose of paracetamol, usually combined with other ingredients in a veterinary-approved medication. But this is based on your dog’s weight, breed, age, and health. You should never attempt to guess the dose or use human medicine without professional guidance.

What to Do If Your Dog Has Eaten Paracetamol

If you think your dog has swallowed paracetamol — even a small piece of a tablet — act fast:

1. Do not wait for symptoms to appear

2. Call your vet immediately

3. If it’s out of hours, contact an emergency veterinary clinic or Animal PoisonLine (UK) on 01202 509000

Early treatment can make a huge difference and may save your dog’s life.

Safe Alternatives for Pain Relief

Never attempt to treat your dog’s pain at home with human medicines. If your dog seems unwell or in pain, speak to your vet, who may prescribe:

• Meloxicam or carprofen – anti-inflammatory medications made specifically for dogs

• Gabapentin – used for nerve pain or chronic discomfort

• Specialist supplements – like joint support for arthritis

These are safer, properly dosed, and formulated for dogs.

Final Thought

Do not give your dog paracetamol unless your vet has specifically prescribed it. Human painkillers can be extremely dangerous for dogs — even in small amounts. If your dog is in pain or has accidentally ingested medication, get veterinary help immediately.
