Can I Give My Dog Paracetamol?

As pet owners, it’s natural to want to relieve your dog’s pain when they seem uncomfortable. One common question we get is, “Can I give my dog paracetamol?”

While paracetamol (also known as acetaminophen) is a household medication for humans, its use in dogs is much more complex and requires veterinary supervision.

In this article, our Chief Veterinarian and Omni Co-Founder, Dr. Guy MRCVS, explores the risks and recommendations surrounding the use of paracetamol for dogs.

Can Dogs Have Paracetamol?

Yes, but strictly only under the advice of a vet.

As of a recent update to UK law, it is now illegal for vets to promote or facilitate illegal off-licence use of medicines in animals without justification. 

Do not give your dog paracetamol without having first consulted a veterinarian. 

Paracetamol can be effective for managing pain in dogs, but it is only ever used as a last line of defence and may cause side-effects in your dog.

Vets are legally bound to prescribe medications specifically designed for pets, such as non-steroidal anti-inflammatory drugs (NSAIDs) like meloxicam or carprofen, which are safer and more suitable for managing pain and inflammation in dogs.

Why Paracetamol Is Not the Best First Option

  • Better alternatives are available: Veterinary NSAIDs are tailored to a dog’s metabolism and offer safer, more reliable pain relief for a range of conditions, from arthritis to post-surgical discomfort.
  • Limited use cases: Paracetamol is only ever recommended for very specific conditions and at specific dosages that your vet will determine based on your dog’s size, age, and pre-existing health conditions. 

Risks of Giving Paracetamol to Dogs

Giving paracetamol without veterinary supervision can lead to serious health risks for your dog.

Toxicity and Organ Damage

  • Liver damage: One of the primary concerns with paracetamol in dogs is its potential to cause liver toxicity. Even a slight overdose can lead to irreversible liver damage for your dog. 
  • Other organ issues: Paracetamol may also affect other organs, particularly the kidneys, which can be fatal if not treated promptly.

In fact, a study published in Companion Animal highlights how dogs metabolise paracetamol differently from humans, making them more susceptible to overdose and organ damage.


Is Paracetamol Ever Safe for Dogs?

While paracetamol may have a place in certain treatment plans, it is an "off-licence" medication for dogs, meaning it has not been approved specifically for canine use. A vet can only prescribe it when there is a justified medical reason, and the dosage must be precise.

In addition, if there is any other option outside of paracetamol, then the vet may face criminal charges for prescribing paracetamol. It is therefore highly unlikely that you will ever find a vet prescribing paracetamol to your dog. 

This is due to prescription guidelines explained in a decision-making model known as 'the Cascade'. 

When Vets Might Prescribe Paracetamol:

  • Special conditions: In rare cases, a vet might recommend paracetamol if other pain relief options are not suitable, for example, if a dog has an intolerance to NSAIDs or other medications.
  • Precise dosing: Only a vet can determine the correct dosage, which is often much lower than what humans take. Never attempt to give your dog paracetamol without professional guidance.

How to Safely Manage Your Dog's Pain

If you suspect your dog is in pain, always consult a vet first. They will be able to assess the situation and recommend the most appropriate treatment plan. Common alternatives to paracetamol include:

  • NSAIDs: These are typically safer for managing pain and inflammation in dogs.
  • Joint supplements: For chronic conditions like arthritis, supplements such as glucosamine and omega-3 fatty acids can help reduce inflammation and pain over time.
  • Prescription pain relief: Your vet might prescribe medications that are specifically designed for dogs, ensuring effective and safe treatment.

Speak with a Vet If…

  • You are unsure about your dog’s symptoms or the appropriate course of action.
  • Your dog has pre-existing conditions like liver or kidney disease, which could increase the risk of complications.
  • You need advice on pain management and suitable alternatives to paracetamol.

Book a free consultation with Omni’s veterinary team to get expert advice on your dog’s health and pain management strategies. Never self-medicate your dog with human medications without professional guidance.

Thoughts from Dr Guy MRCVS


As dog lovers and guardians, it’s natural to worry about our furry friends, especially when they display abnormal symptoms that can’t be easily explained. That’s why, when I founded Omni, I knew that I wanted to keep vet consultation free and accessible at the heart of the business. 


If you’re understandably worried about your dog, but you don’t think you need to take them to the vets urgently, I highly recommend getting some friendly, professional advice from one of our team.

FAQs

But aren’t dog’s carnivores?

Dogs are in fact nutritional omnivores as demonstrated by a robust scientific study published in the reputable journal Nature (1,2) in which it was shown that they have 30 copies of the AMY2B gene responsible for digesting plant-based foods.

They have also evolved relatively long intestines (21) (almost as long as humans) and relatively flat surfaces on their molars (31, 22) which they use for digesting and chewing a whole range of foods.

The common misconception that dogs are carnivores probably arises from the fact that they are classified in the order Carnivora but so are plenty of other species like bears, skunks, racoons who are omnivores and even the giant panda who thrives on a plant-based diet (20).

Is plant protein digestible to dogs?

Absolutely yes, studies which have looked at how much protein dogs can absorb from plant-based and fungi-based foods like soya and yeast demonstrated over 75% digestibility which is on par with meat-based foods (23, 24, 34, 35 & 25).

Both these protein sources also contain all 10 essential amino acids (36, 37) that dogs need to thrive.

Isn't there too much fibre in plant-based food?

The average amount of fibre in a commercial dog food diet is between 2-4%. omni’s plant-powered recipe has a fibre content of 3% which is on par with meat- based diets.

In our survey with over 200 dog owners, 100% reported that their dog’s stool consistency was either ‘normal’ or ‘perfect’ and there were no reports of any digestive upsets (data on file).

Can I mix omni with other meat-based diets?

We are proud that our recipes are nutritionally complete and so include everything your dog needs to thrive. This means omni can be fed as a sole ration. We also fully support a 'flexitarian approach' like meat free lunches or using omni as a mixer.

Every little helps to bring some of the health and environmental benefits of plant-power to meal times. Mixing omni with meat/fish will help to add variety into your dog’s diet whilst adding in healthy ingredients with a relatively low carbon footprint.

Can plant-based food provide the essential fatty acids dogs need?

All the essential fats and oils that dogs need, including omegas 3 and 6 are found in a variety of both meat and plant-based foods (31, 28).

omni’s recipe is rich in plant-based sources of these nutrients so your dog will get all the essentials they need.

I hear a lot about feeding raw meat, isn’t that better?

Feeding raw meat to dogs has become a very popular trend in recent years, but most vets will warn against this practise. This is because the cooking process is vital to help kill off dangerous bacteria like E coli, Salmonella and Campylobacter (9) that have necessitated several food recalls from the market and caused serious illness and even death in both dogs and their owners (40, 41, & 42).

There are also several worms and parasites that are only killed off when raw meat is cooked. Dogs are dogs, not wolves and thanks to their domestication over thousands of years, thankfully don’t need to hunt to get their grub nor do they need to eat raw meat, it's just not worth the risk.
