Can My Dog Eat This? A List of Human Foods Dogs Can and Can't Eat

Certain human foods, like carrots and blueberries, can be safe for most dogs. But others, like garlic and onions, can be toxic.

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 53 foods and whether or not your dog can eat them.

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: Cant 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 (2).

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

Salt should be limited in your dogs 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 (3).

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 dogs peanut butter intake. Since peanut butter is high in fat and calories, it may lead to weight gain if he eats too much (4, 5).

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 (3).

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 (7).

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 dogs skin and fur healthy (8, 9).

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 (10).

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 (11).

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 (12).

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

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

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 (13, 14).

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

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 dogs health (15, 16, 17, 18).

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

Dogs can eat popcorn as an occasional treat, as long as it doesnt 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 (3, 11, 19).

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 dogs teeth, so you should only provide your dog with fully-popped kernels.

You should limit your dogs 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 (4, 11).

It is best to limit almonds in your dogs 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.

Additionally, pineapple is full of many vitamins, minerals and fiber, making it an excellent nutrient-dense snack for your dog (21).

Similar to other foods, dogs may experience symptoms like nausea and diarrhea if they eat too much pineapple. Thus, it is best to feed your dog a small amount of pineapple at a time.

You should never feed your dog onions.

Onions contain N-propyl disulfide, a compound that is toxic to dogs. It can damage your dogs red blood cells, reducing their ability to carry oxygen through the body. This often results in a condition called anemia (22, 23).

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 (22, 24).

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.

Watermelon is safe for dogs to eat, as long as it doesnt 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.

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.

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).

Although plain, cooked corn kernels are safe for dogs, you should never feed your dog corn on the cob. The cob is a choking hazard and could lead to intestinal obstruction if consumed.

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

Green tomatoes, on the other hand, may contain small amounts of tomatine, a toxic glycoalkaloid. While green tomatoes are not toxic to people, anecdotal evidence suggests it may harm dogs. (28).

Dogs that consume too much tomatine from tomatoes may experience nausea, an abnormal heart rate, muscle weakness and difficulty breathing.

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

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 dogs digestive system (33, 34).

Coconut is safe for dogs to consume.

Additionally, feeding coconut meat or coconut oil to dogs as an occasional treat has been anecdotally claimed to benefit their skin and fur.
