One of the most common things that can go wrong with your dog is that they have eaten, inhaled or absorbed something toxic. Toxic ingestion (eating) is the most common - no surprises there!

A study conducted by Direct Line Pet Insurance in 2021 found that 28% of dog owners believe that their pet fell ill after consuming something poisonous. The same study found that 7% (approximately 342,000 dogs) lost their lives as a result.

Let's look at how to prevent toxicity complications in dogs, the warning signs and some of the most common toxins.

Toxicity In Dogs

As owners it is vitally important that we are able to recognise the signs and take prompt action. In this edition, our friends at Dog First Aid Training Ltd will be sharing information on toxins that can affect kidney function.

As a first aider, the 3 most important things to remember are:

Avoidance

By keeping toxic substances completely out of reach from your pooch you will significantly reduce the risk of them being poorly.

As well as known toxic substances like rat poison, bleach and weed killers there are many things that are safe in moderation for humans that will not be safe for your dog.

Examples of human foods not safe for your dog include chocolate, grapes, some medications, plants, essential oils and xylitol.

Never Watch And Wait

If you find evidence that your dog has eaten something poisonous, do not wait until you see symptoms. Some symptoms can take up to 48 hours to develop but not taking immediate action could risk your dog's life.

Recognise The Symptoms

Depending on the toxins and the body system it affects, you could see a range of symptoms including:

  • Vomiting
  • Diarrhea
  • Excessive Drinking
  • Excessive Urination
  • Incoordination
  • Lethargy
  • Drooling
  • Seizures
  • Yellowing Of The Gums

Treatment at home is never advised for toxicity - your dog needs to be seen by a veterinary professional. Treatment will vary depending on the toxin and the severity of the case.

Fortunately, in the majority of cases, dogs go on to make an excellent recovery when prompt treatment is sought.

Lesser Known Toxins That Can Affect Kidney Function In Dogs

Here are some toxins that can affect kidney function in dogs. If you suspect your dog has ingested any of these, contact your vet immediately.

1. Non Steroidal Anti-Inflammatory Drugs (NSAIDS)

Products such as Ibuprofen, Diclofenac, Naproxen and Celecoxib are extremely harmful. A single 200mg tablet can be fatal for smaller dogs.

2. Vitamin D

Available in tablet form but also a common ingredient in topical psoriasis creams and rodent poisons.

A high amount of vitamin d is toxic to dogs. Renal failure can occur in 24-28 hours.

3. Antifreeze

Whether licking from a spillage or even from their paws, antifreeze affects the central nervous system, causes gastrointestinal issues, and affects the liver, brain and kidneys.

4. Grapes, Raisins, Currants and Sultanas

There are some fruits and vegetables suitable for dogs however ensure your dog doesn't eat any of the above. 

It has been reported that in small dogs a single fruit can be a fatal dose.

5. Antibiotics

Products such as Ibuprofen, Diclofenac, Naproxen and Celecoxib are extremely harmful. A single 200mg tablet can be fatal for smaller dogs.

The most effective way of avoiding issues with these substances is to keep them safely out of reach of your dog at all times.
