Dogs and humans metabolize foods differently.

For this reason, some foods are safe for humans to eat but may be toxic and potentially deadly for dogs.

On the other hand, there are many human foods that are perfectly safe and even healthy for dogs to eat as an occasional treat.

This article gives an overview of best dog food brands and whether or not your dog can eat them.

1. Carrots: Can Eat

Both raw and cooked carrots are safe for your dog to eat.

Carrots are low in calories and a good source of vitamins, minerals and fiber. This makes them a very healthy food for your dog to snack on (1).

Before feeding carrots to your dog, make sure to cut them into bite-size pieces to prevent choking.

2. Grapes and Raisins: Can’t Eat

You should never feed grapes or raisins to your dog.

Grapes and raisins contain toxic compounds that are harmful to dogs. They have the potential to lead to rapid kidney failure and death (2Trusted Source).

Even small amounts of grapes and raisins can make your dog sick, so it’s important to avoid giving them to your dog altogether.

3. Salt: Limit

Salt should be limited in your dog’s diet.

Excessive salt intake may lead to salt poisoning or water deprivation in dogs, which can cause vomiting, diarrhea, vomiting and seizures. In severe cases, high amounts of salt can be fatal (3Trusted Source).

To prevent adverse effects, you should not feed your dog salty foods, such as chips or pretzels. Furthermore, always make sure your dog has water to drink, which can prevent water deprivation.

4. Peanut Butter: Can Eat

Peanut butter is a healthy and safe treat for dogs to eat in moderate amounts.

However, it is best to limit your dog’s peanut butter intake. Since peanut butter is high in fat and calories, it may lead to weight gain if he eats too much (45Trusted Source).

Also, make sure to feed your dog plain, unsalted peanut butter. Peanut butter commonly has extra ingredients added to it, such as salt, which could be harmful to your dog (3Trusted Source).

5. Eggs: Can Eat

Cooked eggs are perfectly safe and nutritious for dogs to eat.

One medium egg provides some of almost every vitamin and mineral, plus lots of protein. There are claims that eggs may also help relieve nausea in dogs, although there is no scientific evidence behind this claim (6).

It is important to note that you should avoid feeding raw eggs to your dog. While dogs typically do not get sick from eating raw eggs, bacteria, such as Salmonella, can spread from the dog to its human owners, increasing their risk of infection (7Trusted Source).

6. Salmon: Can Eat

Cooked, boneless salmon is a safe and healthy food for your dog.

Salmon is a great source of omega-3 fatty acids, which are known to reduce inflammation and may help keep your dog’s skin and fur healthy (89Trusted Source).

However, you should avoid feeding raw salmon to your dog. It may contain a parasite that is known to cause salmon poisoning disease, which can be fatal (10Trusted Source).

7. Chocolate: Can’t Eat

It is widely known that dogs should never eat chocolate.

This is because chocolate contains theobromine and caffeine, two stimulants that dogs cannot efficiently metabolize (11Trusted Source).

If your dog eats chocolate, he may exhibit symptoms like vomiting, diarrhea and dehydration. These symptoms may lead to more serious complications, such as internal bleeding, muscle tremors, seizures and death (12Trusted Source).

Darker and less sweet varieties of chocolate, such as cocoa powder and unsweetened baker’s chocolate, are more poisonous to dogs than sweetened varieties, such as milk chocolate.

Nevertheless, do not feed your dog any type of chocolate.

8. Cheese: Limit

Cheese is safe for most dogs to eat in small quantities.

Due to the fat and lactose content of cheese, some dogs may have digestive symptoms, such as stomach pain and diarrhea, after eating it (13Trusted Source14Trusted Source).

To avoid unpleasant symptoms, it is best to introduce cheese into your dog’s diet gradually. It may also help to only feed your dog low-fat cheeses, such as mozzarella.

9. Blueberries: Can Eat

Blueberries are safe and nutritious for dogs to eat.

Blueberries are a rich source of disease-fighting antioxidants and provide a significant amount of vitamins, minerals and fiber, all of which may benefit your dog’s health (1516Trusted Source17Trusted Source18Trusted Source).

Moreover, blueberries are low in calories and small in size, making them an excellent health-conscious treat for your dog (15).

10. Popcorn: Can Eat

Dogs can eat popcorn as an occasional treat, as long as it doesn’t contain any extra ingredients.

Salt is often added to popcorn, which can lead to serious complications if your dog eats too much. Butter and oil are other common popcorn ingredients that are high in fat and may lead to pancreatitis in dogs if over-consumed (3Trusted Source11Trusted Source19Trusted Source).

For these reasons, it is best to only feed your dog plain, air-popped popcorn.

Popcorn kernels are also a choking hazard and may get stuck in your dog’s teeth, so you should only provide your dog with fully-popped kernels.

11. Cashews: Limit

You should limit your dog’s intake of cashews.

Plain, unsalted and roasted cashews are safe for most dogs to eat in moderation. However, cashews are high in fat and calories and may lead to weight gain and pancreatitis when consumed in excess (411Trusted Source).

For these reasons, you should limit your dog’s intake to one or two cashews a day or less.

12. Macadamia Nuts: Can’t Eat

Dogs should never eat macadamia nuts.

Macadamia nuts contain an unknown toxin that may lead to vomiting, muscle weakness, tremors, hyperthermia and depression when dogs consume them, even in small amounts (20Trusted Source).

Additionally, macadamia nuts have a high fat content, which may elevate your dog’s triglyceride levels and potentially lead to pancreatitis.

13. Almonds: Limit

It is best to limit almonds in your dog’s diet.

Although plain, unsalted almonds are generally safe for dogs to eat in small amounts, they are difficult for dogs to digest and may lead to vomiting and diarrhea.

Almonds are also high in fat and calories and have the potential to cause weight gain and pancreatitis in dogs. If you feed your dog almonds, it is best to give very small servings (11Trusted Source).

14. Pineapple: Can Eat

Anemia in dogs is characterized by a variety of symptoms, including lethargy, weakness, decreased appetite and fainting. In severe cases, dogs with anemia may need a blood transfusion (22Trusted Source24Trusted Source).

It is important to note that all components and forms of onions are toxic to dogs, even the leaves, juice and processed powders, such as onion powder.

16. Watermelon: Can Eat

Watermelon is safe for dogs to eat, as long as it doesn’t contain the rind or seeds.

Watermelon rinds and seeds could be a choking hazard, and some people claim that they can cause digestive problems in dogs.

17. Cottage Cheese: Limit

Dogs can eat cottage cheese in small amounts.

Plain white or whole grain bread is safe for most dogs to eat as an occasional treat.

Before feeding your dog bread, make sure it doesn’t contain any extra ingredients, such as raisins, which could be potentially harmful.

Additionally, keep in mind that bread, along with other foods, adds extra calories to your dog’s diet and may cause weight gain if he eats too much.

19. Blackberries: Can Eat

You can safely feed your dog blackberries.

Fresh or frozen blackberries are a healthy treat for dogs. They are low in calories and rich in vitamins, minerals and antioxidants. Additionally, blackberries are a great source of fiber (26).

If your dog enjoys blackberries, you can feed him a few each day as a treat.

20. Avocado: Can’t Eat

Avocados should never be consumed by dogs.

This is because they contain a toxin called persin, which is known to be very poisonous to dogs. It may lead to fluid accumulation in their lungs and chest, which can cause breathing difficulties, oxygen deprivation and even death (11Trusted Source).

Persin is found in all parts of the avocado, including the fruit, pit, leaves and bark. Thus, you should always keep avocados away from your dog.

21. Corn: Can Eat

Dogs can eat corn in moderate amounts.

Corn is a good source of some vitamins and minerals and common ingredient in many types of dog food. A tablespoon or two of corn per day is an appropriate serving size for dogs (27).

22. Tomatoes: Limit

It’s okay to feed your dog tomatoes as an occasional treat, as long as they are ripe.

Green peas are a common ingredient in many types of dog food. Not only do dogs find them tasty, but green peas are also low in calories and high in many nutrients, making them a healthy treat for your dog (29).

However, only feed your dog fresh or frozen peas, not canned ones. Canned peas are often loaded with salt, which is harmful to dogs in large amounts (3Trusted Source).

24. Oatmeal: Can Eat

Plain oatmeal is safe for your dog to eat.

Oatmeal provides lots of fiber, as well as some vitamins and minerals (30).

As with all foods, you should feed oatmeal to your dog in moderation to prevent him from gaining weight (4).

Additionally, it is important to only feed plain oatmeal to your dog, instead of flavored oatmeal. Flavored oatmeal may have extra ingredients added to it that could be harmful to your dog.

25. Coffee and Tea: Can’t Eat

Coffee and tea are dangerous for dogs to consume due to their caffeine contents.

Caffeine stimulates your dog’s nervous system, which can lead to a number of symptoms, including hyperactivity, vomiting, diarrhea, elevated heart rate, seizures and tremors (11Trusted Source31Trusted Source).

Lung failure and abnormal heart rhythm may result from too much caffeine, which can ultimately lead to death (31Trusted Source32Trusted Source).

Even small amounts of caffeine can cause adverse effects in dogs, so you should always keep coffee and tea out of your dog’s reach (32Trusted Source).

26. Apples: Can Eat

Apples that have been sliced are safe and healthy for dogs to eat.

Apples provide a significant amount of vitamins, minerals and antioxidants. Also, they are high in fiber, which may benefit your dog’s digestive system (3334Trusted Source).
