Four Toxic Foods to Never Feed Your Dog in Los Angeles

Last Updated on May 25, 2025 by Lori Powell

Why Are Certain Human Foods Are Harmful to Dogs?

Dogs love to eat, but not everything we enjoy is safe for them. Many popular foods can be harmful – even deadly – to our canine companions. With the holidays around the corner, it can be tempting to sneak your dog table scraps, but knowing which foods are toxic is critical for their health and safety.

Here are four toxic foods to avoid giving your dog in Los Angeles and how to act quickly if ingestion occurs.

1. Chocolate: A Dangerous Holiday Treat

Most pet parents know chocolate is highly toxic to dogs, but it remains one of the most common causes of pet poisoning. Not only is the high sugar content horrible for their digestive system, but chocolate also contains theobromine and caffeine, both of which dogs cannot metabolize properly.

Severity of poisoning depends on the type, amount consumed, and the dog’s size. For example, a single chocolate bar can be fatal to a small dog like a Chihuahua but might only cause mild symptoms in a larger dog like a German Shepherd.

Watch for symptoms such as:

• Vomiting and diarrhea

• Restlessness or hyperactivity

• Muscle tremors or seizures

• Increased heart rate

Call your vet or the Pet Poison Helpline immediately if you suspect chocolate ingestion.

2. Grapes and Raisins: A Hidden Kidney Threat

Though grapes and raisins may seem harmless, they are extremely toxic to dogs and can lead to sudden kidney failure, even in small quantities. Veterinarians don’t know exactly what compound in grapes causes the reaction, which is why any amount should be treated as dangerous.

Symptoms may include:

• Vomiting or loss of appetite

• Abdominal tenderness

• Lethargy or weakness

• Increased thirst or urination

This is a true medical emergency. Contact your vet immediately and do not wait for symptoms to appear.

3. Alcohol and Xylitol: A Deadly Mix 

Alcoholic drinks are a big no for dogs, but accidents can happen. Dogs may lick spilled cocktails or wine, and holiday punches often contain sweeteners like Xylitol (also labeled as “birch sugar”), which is highly toxic.

Alcohol can cause:

• Disorientation, restlessness or drowsiness

• Vomiting and excessive panting

• Tremors or muscle seizures

Your dog will likely be more curious about fruit-based drinks, like ciders or punches. Along with your cocktails, most drinks will also require mixers, which often include Xylitol, which, even in small amounts, can lead to dangerous blood sugar drops or liver failure. If your dog has consumed alcohol or a product with Xylitol, seek veterinary care immediately. If a toy breed like a Brussels Griffon happens to drink a bit of wine that accidentally spilled on the floor, it will be much more dangerous for them than if your Labrador licks up the same amount. 

4. Onions and Garlic: Flavorful but Harmful

These common cooking ingredients are toxic in all forms: raw, cooked, powdered, or juiced. They damage red blood cells, leading to anemia, and are particularly dangerous to smaller dogs. Raw onion isn’t the only thing that is harmful to your dog. Onion powder, garlic powder, and the flesh & juices within onions can all lead to a medical emergency.

Look for symptoms like:

• Pale gums

• Lethargy or weakness

• Reddish urine

• Loss of appetite

Dispose of garlic and onion scraps carefully and always keep them out of reach while cooking or cleaning up.

A Note for Cat Parents, Too

Most of these foods are also toxic to cats. If you live in a multi-pet household, make sure none of your pets have access to harmful table scraps or leftovers.

What to Do If Your Dog Eats Toxic Foods

1. Call your vet or the Pet Poison Helpline at 855-764-7661 right away.

2. Do not induce vomiting unless directed by a professional.

3. Be ready to provide your dog’s size, age, the amount ingested, and the time of ingestion.

Preventing Future Incidents Through Training

Prevention is always the best medicine. One of the most effective ways to avoid food-related emergencies is by training your dog to leave dropped or forbidden items alone. Commands like “leave it” or “stay” can be life-saving.
