27 Foods You Should Never Feed Your Dog And 27 That Are Totally Safe

Caring for your furry friend means more than just regular walks and belly rubs—it also involves knowing exactly what goes into their bowl. While it can be tempting to share a bite of your snack with your dog, not all human foods are safe for canine companions. In fact, some everyday ingredients we enjoy can be toxic, even life-threatening, to dogs.

Whether you’re a first-time dog parent or a seasoned pet owner, understanding which foods are harmful and which are healthy can make all the difference in your pup’s well-being. Feeding your dog the wrong treat—no matter how small—can lead to serious health issues, from digestive problems to organ damage. On the flip side, many human foods are not only safe for dogs but can actually provide nutritional benefits when given in moderation.

This guide outlines 27 common foods that you should never give your dog, followed by 27 that are perfectly safe (and even beneficial). It’s designed to help you make confident, informed choices about your dog’s diet—keeping tails wagging and mealtimes worry-free.

Let’s start with the foods to avoid—because when it comes to your dog’s health, prevention is key. Then, we’ll dive into the safe and nutritious treats that your pup will love.

1. Chocolate

Chocolate, beloved by humans, is toxic to dogs. It contains theobromine and caffeine, which can lead to serious health issues. Symptoms like vomiting, diarrhea, and increased heart rate can occur.

In severe cases, chocolate consumption might result in seizures or even death. Even a small amount can be dangerous, so keep all chocolate out of reach. The darker the chocolate, the more toxic it is. Always choose safer treats for your pet.

2. Grapes

Grapes and their dried counterpart, raisins, are extremely harmful to dogs. Even a few can lead to kidney failure in some pets. Symptoms include vomiting, diarrhea, and lethargy.

The exact toxic substance in grapes is still unknown, making them even more mysterious and dangerous. Always keep grapes and raisins away from reach, and inform family members and guests about this hazard. Opt for dog-friendly fruits instead.

3. Raisins

Raisins, like grapes, pose a severe threat to your dog’s health. They can cause kidney failure, leading to serious complications or even death. Symptoms may appear within hours and include vomiting, lethargy, and a lack of appetite.

The specific toxin remains unidentified, which heightens the risk. Ensure raisins are never accessible to your pet, and educate others about their potential danger. Safer snacks are available for our canine friends.

4. Onions

Onions, along with garlic, belong to the allium family, known to be harmful to dogs. They contain compounds that can damage red blood cells, leading to anemia. Symptoms may include weakness, vomiting, and a loss of appetite.

Cooking onions doesn’t eliminate their toxicity, so all forms should be avoided. Keep onions out of your dog’s diet to ensure their safety and health. Seek out non-toxic alternatives for flavoring meals.

5. Garlic

Garlic, though flavorful, is dangerous for dogs. It contains thiosulfate, which damages red blood cells, causing anemia. Symptoms like fatigue, pale gums, and an increased heart rate can occur.

Even small quantities can be harmful, so avoiding garlic in all forms is crucial. This includes raw, cooked, and powdered versions. Safeguard your pet’s health by choosing garlic-free foods and treats, ensuring they remain vibrant and lively.

6. Macadamia nuts

Macadamia nuts may look harmless, but they can cause serious harm to dogs. Consumption leads to symptoms like vomiting, fever, and muscle tremors. The exact cause of toxicity isn’t clear, yet even a small amount can lead to distress.

Dogs may become weak and unable to walk properly. It’s best to avoid these nuts entirely and educate others about their potential danger. Safer nut options are available for curious pets.

7. Xylitol (in gum, candy, etc.)

Xylitol, a common sugar substitute, is extremely toxic to dogs. Found in gum, candy, and many sugar-free products, it can cause a rapid insulin release, leading to hypoglycemia.

Symptoms include vomiting, loss of coordination, and seizures. In severe cases, liver failure may occur. Always check product labels and keep xylitol-containing items out of your pet’s reach. Choose natural sweeteners that are safe for both humans and dogs.

8. Avocados

Avocados contain persin, a substance harmful to dogs. While small amounts might be tolerated, it’s best to err on the side of caution. Symptoms of avocado ingestion include vomiting and diarrhea.

The pit poses an additional choking hazard. Keep avocados and products containing them away from your pet. Always opt for fruits and vegetables that are known to be safe. Your dog’s health is too precious to gamble on avocado treats.

9. Alcohol

Alcohol and dogs are a dangerous mix. Even a small amount can lead to alcohol poisoning, with symptoms such as vomiting, lack of coordination, and breathing difficulties. In severe cases, it can lead to coma or death.

Dogs are more sensitive to alcohol than humans, so never offer alcoholic beverages. Keep all forms of alcohol securely stored away, ensuring a safe and happy environment for your furry companions.

10. Caffeine

Caffeine, found in coffee, tea, and chocolate, is toxic to dogs. It affects their central nervous system and heart. Symptoms of caffeine poisoning include restlessness, rapid breathing, and muscle tremors.

In severe cases, it can cause seizures or heart failure. Keep caffeinated beverages and foods out of your dog’s reach. Educate family and friends about its dangers, ensuring everyone is vigilant about potential exposure.

11. Cooked bones

Cooked bones may splinter and cause serious harm to dogs. They can lead to choking, internal injuries, or blockages in the digestive tract. Despite common myths, cooked bones are not safe for pets.

Always opt for raw, vet-approved bones or dental chews designed specifically for dogs. Prioritize your pet’s safety by removing bones from their diet, and offer them safer alternatives to gnaw and enjoy.

12. Raw yeast dough

Raw yeast dough can expand in a dog’s stomach, causing bloating and discomfort. As the yeast ferments, it produces alcohol, leading to alcohol poisoning. Symptoms include vomiting, belly pain, and lethargy.

Avoid leaving raw dough unattended in your kitchen. Opt for dog-friendly baked goods that don’t involve yeast. By understanding this risk, you can ensure your pet stays happy and healthy, free from unnecessary distress.

13. Blue cheese

Blue cheese contains roquefortine C, a substance potentially harmful to dogs. It can cause vomiting, diarrhea, and tremors. While some dogs might tolerate small amounts, it’s better to avoid offering blue cheese altogether.

Opt for cheeses that are known to be safe in moderation. Keep gourmet cheeses out of reach, ensuring your pet doesn’t accidentally indulge. Choose treats specifically designed for canine enjoyment instead.

14. Moldy foods

Moldy foods can harbor mycotoxins, which are dangerous for dogs. Consumption can lead to muscle tremors, seizures, and vomiting. The toxins present in moldy foods are unpredictable and vary in severity.

Always dispose of moldy food properly, preventing any accidental ingestion by pets. Keep your kitchen clean and organized, ensuring all food is stored safely. Choose fresh, wholesome snacks for your furry friends.

15. Salt

Excessive salt consumption can lead to sodium ion poisoning in dogs. Symptoms include vomiting, diarrhea, and tremors. In severe cases, it might cause seizures or even death.

Dogs’ sodium needs are much lower than humans’, so keeping their salt intake minimal is essential. Avoid sharing salty snacks, and choose low-sodium options for treats. Ensuring your dog’s diet is balanced will help maintain their health and vitality.

16. Fat trimmings

Feeding dogs fat trimmings might seem harmless, but it can lead to pancreatitis. This condition causes inflammation of the pancreas, resulting in vomiting and abdominal pain. Dogs’ digestive systems are not equipped to handle high-fat foods.

Always trim meat properly and dispose of fat safely. Opt for lean meats or specialized dog treats instead. By being mindful of your dog’s fat intake, you can prevent unnecessary health issues.

17. Raw eggs

Raw eggs might expose dogs to harmful bacteria like salmonella. They also contain avidin, which can interfere with biotin absorption, potentially leading to skin and coat issues.

Some dog owners advocate for raw diets, but it’s essential to consult with a vet. Cooked eggs provide a safe and nutritious alternative. Always prioritize your pet’s health by understanding the risks associated with raw foods and opting for cooked options.

18. Raw meat or fish (unvetted)

Unvetted raw meat and fish can pose significant health risks to dogs. They may contain harmful bacteria or parasites, leading to illness. Symptoms include vomiting, diarrhea, and lethargy.

While some owners prefer raw diets, it’s crucial to source meats from reputable suppliers. Consulting with a vet ensures that the diet is balanced and safe. Cooked meats and fish are generally safer, eliminating many of the associated risks.

19. Apple seeds

Apple seeds contain cyanide, which is toxic to dogs. Ingesting them can lead to cyanide poisoning, though a large amount is needed for serious effects. Symptoms include difficulty breathing and dilated pupils.

When offering apples to your pet, remove the seeds and core. Apples are a healthy treat when prepared correctly, providing vitamins and fiber. By safely removing the seeds, you can enjoy peace of mind while sharing this fruit with your dog.

20. Cherry pits

Cherry pits, like apple seeds, contain cyanide and pose a choking hazard. While the fruit itself is safe, the pits must be removed. Symptoms of cyanide poisoning include difficulty breathing and bright red gums.

Always offer pitted cherries or opt for other fruits that don’t require preparation. Providing safe, nutritious snacks helps maintain your dog’s well-being. By understanding this risk, you can make informed choices for your pet’s diet.

21. Peach and plum pits

Like cherries, peach and plum pits contain cyanide and pose a significant hazard to dogs. They can lead to choking or intestinal blockages if ingested.

Symptoms of cyanide poisoning include excessive drooling and difficulty breathing. Always remove the pits before offering these fruits to your dog.

Better yet, choose fruits that are naturally free of pits, ensuring a safe snacking experience. Your dog’s health should always be the priority.

22. Milk and dairy (for lactose-intolerant dogs)

While some dogs enjoy milk and dairy, many are lactose intolerant. This can lead to digestive issues such as diarrhea and gas. Symptoms vary, so it’s essential to monitor your pet’s reaction.

If lactose intolerant, opt for lactose-free alternatives or non-dairy treats. Regular cheese can be given in moderation, provided your dog isn’t sensitive. Understanding your pet’s dietary needs ensures their comfort and health, free from unnecessary discomfort.

23. Coconut water

Coconut water is rich in potassium, making it unsuitable for dogs in large quantities. While generally safe in moderation, excessive consumption can lead to electrolyte imbalances. It’s best to offer plain water and reserve coconut water for special occasions or treats.

Monitoring your dog’s reaction is key to ensuring their safety. By keeping your pet hydrated with appropriate liquids, you support their overall health and well-being.

24. Nutmeg

Nutmeg contains myristicin, a compound toxic to dogs. Ingesting it can lead to symptoms like hallucinations, increased heart rate, and abdominal pain. While used sparingly in cooking, it’s wise to avoid giving nutmeg to pets entirely.

Opt for spices and flavorings that are known to be safe for dogs. Keeping potentially harmful ingredients out of reach ensures a safe environment where your pet can thrive.

25. Cinnamon

Cinnamon, while not toxic, can cause irritation in dogs. Ingesting large amounts might lead to vomiting, diarrhea, or changes in heart rate. However, small amounts used in baking are generally safe.

It’s important to monitor how your pet reacts to cinnamon and adjust accordingly. When in doubt, choose treats and recipes specifically designed for dogs, ensuring their comfort and enjoyment without unnecessary risks.

26. Tomato leaves and stems

Tomato leaves and stems contain solanine, a toxic substance for dogs. Consuming them can lead to symptoms like drooling, vomiting, and heart rate changes. While ripe tomatoes are safe, the green parts must be avoided.

Educate family members about this risk, and remove any plants from areas accessible to pets. Offering ripe, safe fruits ensures your dog’s safety and provides a nutritious treat they can enjoy without worry.

27. Mustard seeds

Mustard seeds can cause gastrointestinal irritation in dogs. Ingesting them might lead to vomiting and diarrhea. While mustard as a condiment is rarely consumed by pets, it’s best to keep seeds and mustard plants out of reach.

Opt for spices and herbs known to be safe for dogs when preparing their meals. Prioritizing your pet’s health means understanding potential hazards and choosing ingredients wisely.
