Your pet’s environment is filled with potential poisons and toxic substances that you might not think too much about on a daily basis. However, it’s crucially important to know about the items in your home, garden, and walking route that pose a danger to your pet, and how to spot if they’ve been poisoned. 

So, how can you tell if your pet has been poisoned? Signs and symptoms of pet poisoning will differ by breed, size, age, and existing health conditions, as well as the poison in question. However, common signs include a change in behaviour, mouth irritation, sickness and diarrhoea, visible burns or bruising, breathing problems, and convulsions.

Read on to learn more about spotting the signs of poisoning in pets, common household and environmental poisons, and what to do if you think that your pet has been poisoned. 

How to Tell If Your Pet Has Been Poisoned

Every animal will respond differently to poisons, depending on their breed, size, age, existing conditions, and how much of the poison that they have consumed. It’s also important to note that the symptoms of poisoning can progress if they aren’t picked up quickly.

Some of the more common signs of poisoning in pets include:

Agitation/Change in Behaviour

You may notice a change in behaviour after your pet eats a toxin, however this will differ based on the type of toxin ingested. For example, stimulants such as chocolate and caffeine may make your pet hyperactive and excitable, whilst a sedative or alcohol may result in depressive behaviour and minimal responsiveness. 

Note that any extreme changes in behaviour should be cause for concern. Consult your vet in these circumstances. 

Excessive/Irregular Drooling

Many pets will experience irritation at the mouth after consuming poison. If you notice your pet excessively drooling or foaming at the mouth, try to remember what your pet has eaten, take a sample, and contact your vet for further advice. 

Sickness & Diarrhoea

Some poisons can cause gastrointestinal problems, such as sickness and diarrhoea. This is one of the more common signs that your pet had ingested a poison.


If your pet suddenly develops loss of appetite, and/or seems nauseous, this may be a sign that they have consumed something toxic. If you are unsure what may have caused this, consult your vet for further advice.

Excessing Bruising or Bleeding

Excessive bruising, bleeding, sores, and burns are signs of external poisoning or caustic substances. This may be the result of plants or chemicals. If you think your pet has come into contact with such a poison, be sure to try and remove toxic substances from the area as soon as possible to minimise irritation. Use paper towels or clean towels to do this. Contact your veterinarian for further advice.

Breathing Problems

There are certain poisons that can affect your pet’s respiratory system, and may cause wheezing, laboured breathing, shortness of breath, slowed breathing, or difficulty breathing. If you believe that your pet is having breathing problems, consult your vet as a matter of urgency. 

Convulsions, Seizures, and Spasms

Many toxins have the potential to affect the nervous system, but prescription medications and toxic plants are common offenders. As such, this can lead to convulsions, seizures, tremors, and muscle spasms. Unless your pet has a condition, (e.g. epilepsy) such symptoms are not normal and should be seen by a vet as soon as possible. These types of toxins can work quickly, with severe consequences.

Common Household Items That May Be Toxic to Your Pet

Your home is full of hidden dangers for pets, and it’s important to be aware of items in your home that are poisonous. For some of these, you may think they’re perfectly harmless, or that they’re out of the reach of your pets, but it’s imperative that you’re aware of common household poisons to keep your pets safe. 




Macadamia Nuts

Grapes and other Dried Fruit



Artificial sweeteners such as Xylitol*



Ethylene Glycol

Mince Pies

*found in common substances such as chewing gum mints, toothpaste, diabetic foodstuffs, sugar free foodstuffs, and vitamins and supplements


Some human medications are toxic to pets and can cause convulsions, spasms, tremors, and seizures. Even where medication is not inherently toxic,  it isn’t formulated for specific animal conditions. Additionally, the dosage of medication is not tailored to the size and weight of pets, where humans are considerably larger than most pets, and can tolerate higher dosages. With these higher, human dosages, pets may overdose. 

Be sure to keep these firmly out of your pet’s reach, and only consider taking them when your pet is not around to avoid accidents. This doesn’t just relate to prescription medications. Did you know that the simple, everyday medication paracetamol can be deadly to cats?


This may be a more obvious poison, and we’re sure that you’d never intentionally feed your pet mouldy food, however, you must ensure that your pet cannot accidentally consume mouldy food (e.g. from the bin). Mould contains mycotoxins, which can cause symptoms such as tremors, seizures, panting, vomiting, weakness, and loss of appetite.

Mould doesn’t just grow on food and, as such, you will need to inspect your home for mould regularly.

What To Do If Your Pet Has Been Poisoned

If you think your pet has been poisoned, you should consult your veterinarian as soon as possible, but here are a few steps you can take in the meantime. 

  • If the poisoning is the result of toxic fumes or gas, get your pet to fresh air immediately
  • If your pet was poisoned by caustic or chemical substances, wear protective gloves and remove the substances from the skin by hand or use paper towels or clean towels to remove liquids. Never use water or other solutions, unless advised by your vet
  • Do not induce vomiting if you suspect your pet ingested a poison
  • Try to identify the poison – think about what your dog could have eaten or had contact with. This may help your vet with diagnosis and treatment
  • Inducing Vomiting

    If your pet doesn’t require emergency treatment to aid their breathing or other critical functions, your vet may first try to induce vomiting in order to remove the poison from the system. However, this can sometimes cause more harm than good, so do not be tempted to try this unless you have been advised to do so by your veterinarian.

  • Endoscopy

    Your vet may choose to carry out an endoscopy to check your pet’s digestive system internally. This will give them a better understanding of how the poison has affected your pet, and can inform suitable treatment.

  • Medications

    In cases where the poison has had time to absorb into the body, your vet may use charcoal to help prevent the poison from absorbing further. Your vet may also prescribe medication to treat the damage caused to your pet’s system by the poison, and help restore normal function. Another option that your vet may take is fluid therapy.

  • Flushing the Stomach

    Your vet may flush your pet’s stomach to try to remove any traces of poison, so that it is not further absorbed into the system.

How Is Poisoning in Pets Diagnosed?

Often, diagnosis can only be made if you have actually observed your pet ingesting or coming into contact with a toxic substance. However, here at Knutsford Vets, we can now send samples of vomit or other bodily fluid from your pet and send it off to a specialist laboratory to determine the exact toxin that is making your pet ill. Results do take a few days but can then help our vets to determine a suitable treatment plan. 

How is Poisoning in Pets Treated?

If your vet is aware of the poison that your pet has come into contact with, they will sometimes be able to give an antidote, if there is one available. However, if the specific poison is uncertain, or there is no antidote, your vet has a number of options to help treat your pet. These can include:

Can You Treat a Poisoned Pet at Home?

In all cases of pet poisoning, you should consult your vet as soon as possible. They will be able to give you advice on first aid and what to do to care for your pet until you can get to the surgery. Once your pet has been examined, you may be able to take your pet home and treat them yourself, following your vet’s treatment plan. Alternatively, you may find that your vet provides initial treatment at the surgery, and provides instruction for further care at home. 

How To Prevent Your Pet From Being Poisoned

As in all walks of life, the best thing you can do is to take steps to prevent disasters from happening in the first place, and this is especially true of pet poisoning. Here are a few simple ways that you can prevent your pet from being poisoned:


Keep your pet away from areas where you know toxic substances are being used. For example, when you’re cleaning, try to keep your pet in a different room, or have someone take them for a walk. Likewise, if you have toxins in your garage, don’t let you pet in there under any circumstances.


Make sure that any common household poisons are stored safely out of the reach of your pets when not in use.


If you’re a plant or flower lover, make sure to only purchase non-toxic ones.


When walking your dog, keep an eye out for common environmental poisons and stay well clear.


If your pet takes medication, be sure to label it carefully and store it away from human medications to avoid accidents.
