8 Human Foods You Should Never Feed Your Dog

When it comes to treating our pets, it’s easy to think a little human food can’t hurt. After all, those puppy dog eyes are hard to resist. But beware—some snacks that seem harmless to us can actually be very dangerous for our four-legged family members.

To help, here’s a list of common human snacks you should keep well out of paw’s reach.

1. Chocolate

Why it’s a no-go: Chocolate is widely known as a no-fly zone for dogs, but it’s just as harmful to cats. Theobromine, a compound found in chocolate, is metabolized much slower by dogs and cats than by humans, leading to potential toxicity. Even a small amount can cause issues such as an irregular heartbeat, seizures, or even death. (ref)

What you need to know: The darker the chocolate, the more dangerous it is. This means that baker’s chocolate and premium dark chocolate are especially risky. Symptoms of chocolate poisoning include excessive thirst, diarrhea, pacing, and severe agitation. If you suspect your pet has ingested chocolate, it’s critical to seek veterinary care immediately to mitigate any risks.

2. Xylitol

Why it’s a no-go: Xylitol, a sugar substitute found in many sugar-free products like gum and candy, can be deadly for dogs and cats. Even small amounts can cause hypoglycemia (low blood sugar), seizures, liver failure, or worse. (ref)

What you need to know: Products that may contain xylitol include toothpaste, mouthwash, baked goods, and some diet foods. Signs of xylitol poisoning can appear in as little as 30 minutes and include vomiting, weakness, and difficulty standing or walking. Always check product labels and keep xylitol-containing items securely out of reach.

3. Grapes & Raisins

Why it’s a no-go: While the exact toxin is unknown, grapes and raisins have been linked to kidney failure in dogs. Cats are generally less likely to eat them, but they are still risky. (ref)

What you need to know: Even a small number of grapes or raisins can cause a reaction in some dogs, while others may ingest larger amounts without immediate effects. However, it’s best not to gamble with your pet’s health. Symptoms include vomiting, lethargy, and depression. If you suspect your pet has eaten grapes or raisins, contacting your vet immediately is crucial.

4. Onions & Garlic

Why it’s a no-go: Onions and garlic can destroy a dog or cat’s red blood cells, leading to anemia. This is true for raw, cooked, or even powdered forms found in some snacks and seasonings. (ref)

What you need to know: Symptoms of anemia from onion or garlic ingestion might not appear immediately. Watch for signs like weakness, vomiting, little interest in food, and breathlessness. Prevention is straightforward: keep these foods out of your pet’s reach and be mindful of feeding them table scraps that might contain these ingredients.

5. Alcohol

Why it’s a no-go: Alcohol has the same effect on a dog or cat’s liver and brain that it does on humans, but it takes far less to do damage. Even small amounts can cause vomiting, diarrhea, coordination problems, breathing issues, coma, or even death. (ref)

What you need to know: This includes beverages and food products that contain alcohol. Never leave your drink unattended where a curious pet might sneak a sip. If you think your pet has consumed alcohol, contact your veterinarian or an emergency animal hospital immediately.

6. Caffeine

Why it’s a no-go: Like chocolate, caffeine is a big no for pets. Found in coffee, tea, soda, and energy drinks, caffeine can be just as stimulating for pets as it is for humans—but with dangerous effects. Even small amounts can cause rapid breathing, heart palpitations, and muscle tremors. (ref)

What you need to know: Symptoms of caffeine poisoning include restlessness, rapid breathing, heart palpitations, and muscle tremors. In severe cases, ingestion can be fatal. Always keep caffeinated beverages and foods out of reach, and never assume your pet can handle a small sip.

7. Macadamia Nuts

Why it’s a no-go: Macadamia nuts, while tasty for humans, are a known hazard for dogs. These nuts contain an unknown toxin that adversely affects dogs, even in small quantities. The precise toxic component and its mechanism haven’t been pinpointed, but the symptoms in dogs can be severe, ranging from weakness in the hind legs to more critical conditions like hyperthermia and depression​ (ref)​.

What you need to know: Symptoms often appear within 12 hours of ingestion and can include vomiting, ataxia (loss of coordination), weakness, hyperthermia, and tremors. Even a small amount of nuts can make a dog ill, so it’s important to keep all such snacks securely out of their reach.

8. Bones

Why it’s a no-go: It’s a common misconception that all bones are safe for dogs. Cooked bones, especially those from poultry, can splinter and cause choking or serious damage to the dog’s mouth, throat, or intestines. Even raw bones pose risks, such as broken teeth and intestinal blockages. (ref)

What you need to know: If you do choose to give your dog bones, ensure they are raw and appropriate for your dog’s size. Always supervise your pet while they’re chewing. Signs of complications include sudden onset of drooling, an inability to swallow, and pawing at the mouth or throat. Immediate veterinary attention is necessary if you suspect your dog has ingested bone fragments.

Keep Your Dog Safe

Our pets rely on us to make the right choices for their health, and it’s up to us to ensure what’s within their reach is safe for consumption. By keeping these snacks out of reach, you can prevent potentially dangerous situations and keep your furry friends safe and healthy.

Remember, when in doubt, keep it out! Always consult your vet if you’re unsure about certain foods or if your pet has eaten something they shouldn’t have.
