Food: What to Feed and Not to Feed Dogs
If there is one universal truth about dogs, it is this: they are convinced that whatever you're eating belongs to them.
You open a bag of chips—two eyes appear.
You sit down with dinner—a furry face materializes beside your chair.
You eat an apple—the dog suddenly becomes extremely interested in healthy eating.
Those puppy-dog eyes can be difficult to resist. But before you share your snack, stop and ask: “Can my dog actually eat this?”
Some human foods are perfectly fine as occasional treats. Others can cause serious illness or even become life-threatening. Knowing the difference is an important part of being a responsible dog owner.
The Foundation: A Balanced Dog Diet
Before we talk about treats, let's start with the most important food your dog eats: their regular dog food.
Dogs need a complete and balanced diet that provides the nutrients they require for their age, size, activity level, and health. A good-quality commercial dog food can provide this nutritional foundation, while homemade diets should be formulated carefully with veterinary guidance to avoid nutritional deficiencies.
Human food should therefore be treated as exactly that—a treat.
It shouldn't replace your dog's normal meals, and even healthy foods can cause problems if you give your dog too much. Treats should generally make up only a small portion of their daily calories; the Post Office guide recommends keeping treats below 10% of a dog's daily caloric intake.
Think of human food as the occasional bonus, not the main event.
Foods Dogs Can Enjoy
So, what can you safely sneak into your dog's treat rotation?
Carrots
Crunchy, simple, and naturally low in calories, carrots can make a convenient treat for many dogs. You can offer them raw or cooked, provided they're prepared appropriately and cut into suitable pieces.
Some dogs may even treat a carrot like the world's greatest chew toy.
Apples
Apples can provide vitamins and fiber and make a refreshing snack. However, always remove the seeds, stem, and core before giving them to your dog.
A few bite-sized slices are plenty.
Blueberries and Other Dog-Friendly Fruits
Blueberries, strawberries, watermelon, and some other fruits can be offered in moderation. They can provide vitamins, minerals, fiber, and antioxidants.
Just remember that fruit contains natural sugars, so a handful is a treat—not an invitation to start a canine fruit buffet.
Lean, Plain Meat
Plain, properly cooked meats such as chicken or turkey can be useful occasional treats. Remove excess fat, skin, and bones, and don't add salt, garlic, onion, butter, or heavy seasoning.
Your dog may look at you as though you've just served a five-star meal.
Eggs
Fully cooked eggs can be a good source of protein for dogs. Keep them plain and avoid serving them with salt, butter, oil, or seasoning.
Peanut Butter—But Check the Label
Many dogs love peanut butter, and small amounts can be a tasty treat.
But there's one very important rule: check the ingredients.
Some peanut butter and other sugar-free products contain xylitol, a sweetener that can be extremely dangerous to dogs.
If you're unsure, don't share it.
Foods That Belong on the “Absolutely Not” List
Now we get to the important part.
Some foods that are completely normal for humans can be dangerous for dogs.
Chocolate
Chocolate is one of the most well-known foods dogs should never eat.
It contains theobromine, a substance dogs process differently from humans. Depending on the amount and type of chocolate consumed, poisoning can cause vomiting, diarrhea, abnormal heart rhythms, tremors, seizures, and potentially death. Darker chocolate generally poses a greater risk because it contains more theobromine.
So keep the chocolate stash somewhere your dog absolutely cannot reach.
And yes, that includes the chocolate hidden in the back of the cupboard.
Grapes and Raisins
Grapes and raisins can cause acute kidney failure in dogs, and there is no established safe amount. They can be dangerous whether eaten fresh or as ingredients in other foods such as baked goods.
If your dog eats grapes or raisins, don't wait to see whether symptoms appear. Contact a veterinarian immediately.
Onions, Garlic, Chives, and Leeks
These belong to the Allium family and can damage a dog's red blood cells, potentially causing anemia. They can be dangerous whether they're raw, cooked, powdered, or dehydrated.
This is particularly important because onion and garlic can hide in foods you'd never think of as dangerous, including sauces, seasonings, leftovers, and processed foods.
That delicious-looking piece of seasoned chicken? Maybe keep it on your plate.
Xylitol
Xylitol is a sugar substitute found in some chewing gums, candies, baked goods, toothpaste, and other products. In dogs, it can trigger a rapid release of insulin and cause dangerously low blood sugar. In serious cases, it can lead to seizures, liver failure, or death.
Always check ingredient labels, particularly on products marketed as “sugar-free.”
Macadamia Nuts
Macadamia nuts can cause poisoning in dogs, with signs including vomiting, weakness, lethargy, loss of muscle control, and elevated body temperature.
And if they're covered in chocolate?
That's two reasons to keep them far away from your dog.
Alcohol and Caffeine
Alcohol is toxic to dogs and can affect their nervous system, breathing, blood sugar, blood pressure, and body temperature. Caffeine can also cause serious problems involving the heart and nervous system and can be fatal in large enough amounts.
That means your morning coffee stays yours.
Your dog has no need for a caffeine boost before their morning walk.
Cooked Bones
Bones may seem like a natural dog treat, but cooked bones can splinter and cause choking, digestive tract injuries, or intestinal blockages. They can even damage teeth while being chewed.
So don't assume that “dogs love bones” means every bone is safe.
What About Dairy?
Dairy products aren't necessarily toxic, but many dogs have difficulty digesting lactose. Milk and other dairy products can therefore cause digestive upset, including vomiting or diarrhea, and high-fat dairy foods may contribute to other health problems.
If your dog does tolerate small amounts of plain yogurt or cheese, they can sometimes be used as occasional treats—but moderation matters.
A Few Simple Rules Make Feeding Much Safer
You don't need to memorize every food in the supermarket.
Instead, follow a few simple habits:
Keep food plain. Avoid salt, sugar, sauces, spices, butter, and oils when sharing human food.
Start small. Introduce new foods one at a time and in small amounts so you can see how your dog reacts.
Remove dangerous parts. Seeds, pits, stems, cores, shells, and bones can create poisoning, choking, or obstruction risks.
Watch the calories. Even safe foods can contribute to unhealthy weight gain when given too frequently.
Read labels. Ingredients such as xylitol can turn an innocent-looking snack into a dangerous one.
And when you're unsure about a particular food, ask your veterinarian rather than guessing.
What If Your Dog Eats Something Dangerous?
This is where acting quickly matters.
If your dog eats a food known to be toxic—especially chocolate, grapes or raisins, onions or garlic, xylitol, macadamia nuts, alcohol, or another potentially poisonous substance—contact your veterinarian immediately. Don't wait for symptoms to appear.
Signs of poisoning can include vomiting, diarrhea, weakness, lethargy, tremors, seizures, excessive panting, changes in coordination, collapse, or other unusual behavior.
Keep the packaging or ingredient list if possible. Knowing exactly what your dog ate, how much they ate, and when they ate it can help the veterinarian determine the appropriate response.
Love Them Without Sharing Everything
Feeding your dog doesn't have to mean sharing every bite of your dinner.
Sometimes the most loving thing you can do is resist those enormous eyes.
Give them their balanced dog food. Offer appropriate treats. Share a few pieces of carrot or apple when suitable. Keep dangerous foods safely out of reach.
And remember: your dog doesn't actually need the last piece of chocolate cake.
They already have something much better.
You.
Although, if you happen to have a carrot, they would probably like that too.
