Toxic Fruits for Dogs

It’s mind-blowing to know that certain fruits we enjoy can harm dogs. Here’s the list of poisonous fruits for dog which we need to avoid:

  1. Grapes and Raisins
  2. Avocados
  3. Cherries
  4. Damsons
  5. Citrus Fruits (lemons, limes, oranges, grapefruits)
  6. Elderberries
  7. Durians

These fruits contain compounds like persin (in avocadoes), psoralen and limonene (in citrus fruits), and cyanide (in elderberries and cherries) that are toxic to dogs.

These toxins can harm their organs, cause digestive issues, or lead to severe health problems. Even non-toxic fruits can pose risks like choking or upset stomachs if consumed in large quantities.

Toxic Nuts for Dogs

Due to limited digestive enzymes, dogs cannot digest some nuts, and this causes poisoning in dogs. Here’s the list of nuts to avoid:

  1. Macadamia Nuts
  2. Pine Nuts
  3. Hickory Nuts
  4. Walnuts
  5. Pecans
  6. Almonds (in large amounts)

Certain nuts contain poisonous compounds like juglone and tremorgenic mycotoxins that can cause serious health issues in dogs. These toxins can affect the nervous system, lead to digestive upset, or even cause muscle tremors.

Did You Know??

Studies have shown that juglone is present in considerable amounts in all green and growing parts of trees and the unripe hulls of nuts.

Toxic Proteins for Dogs

Although most proteins are safe for dogs, certain kinds of proteins should be avoided because they can contain harmful bacteria or toxic compounds that cause severe health issues. These can lead to digestive upset, infections, or even organ damage.

Here are the dangerous proteins to avoid:

  1. Raw Meat
  2. Fatty Meats
  3. Bones
  4. Raw Fish
  5. Raw Eggs
  6. Processed Meats (e.g., sausage, bacon)

Toxic Dairy for Dogs

Certain dairy products can harm dogs, even though they may seem like a treat. Here’s the list of dairy products that are toxic for our pets:

  1. Milk (for lactose-intolerant dogs)
  2. Cheese (especially high-fat varieties)
  3. Chocolate
  4. Yoghurt with added sugars or xylitol
  5. Ice Cream (with xylitol or high sugar content)
  6. Sour Cream

Many dogs are lactose intolerant, means they cannot digest lactose, a sugar in milk. Consuming dairy can lead to digestive problems, such as diarrhea, bloating, or stomach cramps. Some dairy products also contain high fat levels, which can cause more severe issues.

Alcohol

Alcohol is extremely dangerous for dogs. Even small amounts can be deadly. Alcohol consumption can result in vomiting, diarrhea, difficulty breathing, and potential coma.

What Makes Certain Foods Toxic to Dogs? 

You might wonder why these compounds that are safe for humans are deadly for dogs. You must know that dogs process food differently than humans do.

  • Dogs’ digestive systems are designed for meat-based diets, with a shorter tract and faster digestion. Unlike humans, dogs lack some digestive enzymes, such as amylase in saliva, which makes them less efficient at digesting grains, sugars, and other carbohydrate-rich foods.
  • Dogs metabolize some substances much slower than we do, allowing toxins to build up and cause harm more easily. Their metabolism is adapted to derive nutrients from animal proteins and fats, making some human foods indigestible or even toxic for them.
How Toxins Affect Dogs?
  • Organ Damage: Certain toxins can seriously damage organs like the liver and kidneys, leading to long-term health problems.
  • Blood and Nervous System Issues: Foods like onions, garlic, or macadamia nuts can attack the blood or nervous system, causing anaemia, weakness, or seizures.
  • Digestive Upset: Many toxic foods cause immediate vomiting, diarrhea, or stomach pain, resulting in distress in the digestive system.

Symptoms of Toxic Food Ingestion In Dogs

If your dog eats something toxic, they may show signs of poisoning. It’s important to recognize these symptoms so you could take actions quickly. Watch for these signs:

  • Vomiting or diarrhoea
  • Drooling or foaming at the mouth
  • Blood in stool
  • Lethargy or weakness
  • Loss of appetite
  • Shaking or seizures
  • Trouble breathing
  • Uncoordinated movements or staggering

What to Do If Your Dog Eats Toxic Food? 

The first thing you need to do if your dog eats something harmful is to stay calm. Then, follow these steps:

  1. Remove any remaining toxic food from your dog’s reach.
  2. Watch your dog for any symptoms of poisoning.
  3. If you suspect any symptom, Call your vet or a pet poison control hotline immediately and ask for help.
  4. Follow your vet’s instructions exactly. In some cases, they may suggest inducing vomiting or bringing your dog in for treatment.
  5. Only try home remedies with vet approval, as some may make things worse.

I, Dr. Musky Abal, as an experienced veterinarian and dog food specialist, recommend that even if your dog seems fine, but you know they’ve eaten something toxic, take them to the hospital immediately. Early treatment can make a big difference in preventing serious health issues.

Prevention Tips

Preventing your dog from eating toxic foods is the best way to keep them safe. Here are some simple tips to help:

FAQs

How do I know if my dog has ingested toxic food if I didn’t see it happen?

Look for signs like vomiting, diarrhoea, drooling, lethargy, or difficulty breathing. Symptoms can vary depending on the toxic food. If your dog suddenly shows unusual behaviour or physical symptoms, they may have eaten something harmful.

Are certain dog breeds more sensitive to toxic foods than others?

Yes, some breeds may be more sensitive due to their genetic makeup or size. Smaller breeds tend to be at greater risk because even small amounts of toxic foods can greatly impact them. Always consult your vet about specific breed sensitivities.

Can dogs build immunity to some toxic foods over time?

No, dogs cannot build immunity to toxic foods. In fact, repeated exposure to harmful substances can lead to worsening symptoms or long-term health issues.

Can some dogs tolerate foods that are generally considered toxic to others?

While some dogs may show fewer symptoms, this doesn’t mean the food is safe. Every dog is different, but toxic foods can cause hidden damage to their organs, even if symptoms aren’t immediately visible. It’s best to avoid all toxic foods, regardless of tolerance.

What’s the safest way to induce vomiting if my vet advises it?

If your vet instructs you to induce vomiting, they may recommend using hydrogen peroxide. Only do this with veterinary advice, as it can be dangerous. Always follow your vet’s instructions carefully to ensure your dog’s safety.

Why can some human foods be safe for dogs in small amounts but toxic in large quantities?

Some foods contain compounds that are only harmful when consumed in large quantities. For example, cranberries are safe in moderation but can cause issues in large amounts. Dogs metabolize food differently, so the buildup of these compounds can lead to toxicity.

How quickly will symptoms appear after my dog eats something toxic?

Symptoms can appear within minutes to hours, depending on the food and how much your dog ate. Some toxins, like chocolate, may show effects quickly, while others, like grapes, might take several hours. Always monitor your dog closely if you suspect ingestion.

What alternatives should I offer my dog if they accidentally eat something toxic?

After removing any toxic food from your dog’s environment, offer plenty of water to help flush their system (unless your vet advises otherwise). Stick to safe foods like plain cooked chicken, carrots, or rice while monitoring for symptoms.

Are any foods that seem harmless but are frequently overlooked as toxic for dogs?

Yes, some surprising examples include grapes, raisins, macadamia nuts, and xylitol (found in sugar-free products). Even small amounts of these can be dangerous. Always check ingredients before sharing food with your dog.

How can I tell if my dog is lactose intolerant?

If your dog experiences diarrhea, gas, or bloating after consuming dairy, they may be lactose intolerant. Many dogs lack the enzyme needed to digest lactose, so it’s best to avoid giving them milk-based products.

What are the long-term health effects if my dog eats toxic food but seems fine afterward?

Even if your dog seems fine, toxic foods can cause hidden damage to organs like the liver, kidneys, or nervous system. Long-term effects could include digestive issues, organ failure, or decreased energy. It’s essential to consult your vet for a thorough evaluation.

Are there other common household items that could be toxic to my dog?

Yes, household items like cleaning products, medications, certain plants (e.g., lilies), and even certain essential oils can be toxic to dogs. Keep harmful substances out of reach and dog-proof your home to prevent accidental poisoning.
