What foods must dogs never eat?

 17 Foods That Can Harm Your Dog: A Must-Know List

   As pet owners, we all know the look our furry companions give us while we're whipping up a delicious meal at the kitchen counter. Their eager eyes gaze upon us, begging for a bite of what we're cooking. Though it may be tempting to share a taste, it's essential to know what human foods can be harmful to our dogs.

   Digestive systems of dogs and humans differ, and many human foods that we enjoy can be toxic or indigestible for them. It's crucial to understand which foods pose a threat to our canine friends, so we've compiled a list of the most common human foods to avoid feeding your dog.

   So, if you're someone who loves to share a bite with your beloved pet, make sure you understand what they can and cannot eat. This will ensure they stay healthy and happy while they wait eagerly by your side in the kitchen.

Poisonous Foods to Avoid for Your Canine's Safety

   Dogs, as members of the Canidae family, are naturally carnivorous creatures and their diets should primarily consist of meat for optimal health. While incorporating small amounts of fruits and vegetables can provide additional nutrients, it is crucial to exercise caution and make informed choices when selecting these items to include in their diets. To ensure the safety of your furry friend, it is essential to be knowledgeable and mindful of the ingredients in their food and be attentive to any potential dangers that may exist within it.



  After a hectic day, many individuals turn to the comfort of a cold beer or a glass of wine to unwind. However, it is important to keep in mind that even trace amounts of alcohol and alcoholic beverages can pose a serious threat to our four-legged friends. Unlike humans, dogs lack the capacity to properly metabolize and eliminate alcohol, which can lead to a range of harmful effects.

    Ingestion of alcohol can result in symptoms such as vomiting, diarrhea, depression of the central nervous system, difficulty breathing, tremors, coma, and even death. It is imperative to seek immediate medical attention should your pet have consumed any form of alcohol, by contacting either the Animal Poison Control Center or your trusted veterinarian. In order to protect your furry companion, it is best to steer clear of any alcohol-containing food or drinks, and ensure their well-being and safety at all times.



  While avocados are a popular and highly nutritious food for humans, they can have adverse effects on our canine companions. Despite being better tolerated than by horses and birds, dogs still have a difficult time digesting avocados. Consuming large amounts of this fruit can lead to cardiovascular complications, highlighting the importance of monitoring and regulating the foods we share with our furry friends. To maintain the health and well-being of your dog, it is recommended to avoid giving them avocados or limit their consumption to small amounts under veterinary supervision.



   Contrary to popular belief, not all bones are suitable for dogs. While bones from livestock, such as beef or pork, can provide valuable nutrients and chewing satisfaction for dogs, it is crucial to ensure that they are raw and uncooked to prevent splintering and potential harm to the digestive system. On the other hand, bones from birds, such as chicken or turkey, should be avoided altogether due to their brittle and easily splintering nature. Cooked bones, regardless of the source, can also splinter and present a choking hazard.

    Therefore, it is important to exercise caution and carefully assess the suitability of bones before offering them to your furry friend. If in doubt, it is always best to consult with a veterinarian to determine the best options for your pet. Pet stores may sell bones, but it is vital to thoroughly research and understand the source, processing and safety of these bones before offering them to your dog.


   As coffee-lovers, it's tempting to share a sip or two with our furry companions. However, caffeine, the key stimulant in coffee, contains methylxanthines which can have harmful effects on our dogs if ingested. Methylxanthines can lead to symptoms such as vomiting and diarrhea, excessive thirst and urination, panting, hyperactivity, tremors, seizures, and in severe cases, even death.

   It is important to note that the sensitivity and tolerance to caffeine varies among different species, and dogs are particularly vulnerable to its toxic effects. As such, it is crucial to keep all caffeinated beverages, including coffee, tea, soda, and chocolate, out of reach from your pet and ensure that they do not consume any products containing caffeine. By doing so, we can safeguard their health and ensure that our beloved pets are free from harm.


   While it may seem like a treat to share human sweets with your furry friend, it is important to consider the harmful effects that sugar can have on a dog's health. Consuming even small amounts of sugar can cause elevated heart rate and hyperactivity due to the presence of artificial preservatives. Overindulgence in sugary treats can lead to the development of serious health conditions such as diabetes and excessive weight gain, which can negatively impact your pet's overall well-being. It is recommended to avoid offering sugary treats and opt for dog-friendly alternatives such as fruits and vegetables, to ensure your pet remains healthy and happy.


    Chocolate is a highly toxic food for dogs, as it contains harmful substances known as methylxanthines, which can be found in both the cacao seed used to make chocolate and coffee. 

It is imperative that pet owners take caution and keep all forms of chocolate away from their furry friends, as the effects of ingestion can be severe and potentially fatal. Dark chocolate and baking chocolate pose the greatest danger, as they contain the highest concentration of cacao and methylxanthines. Despite its lower methylxanthine content, even white chocolate should not be offered to dogs, as it can still cause harmful effects. It is recommended to opt for dog-friendly treats and avoid offering chocolate to ensure the health and well-being of your beloved pet.

7.Citrus fruit


  While it may be tempting to offer your dog a slice of lemon or other citrus fruit as a treat, it is important to consider the potential consequences of such an action. Citrus fruits, including lemons, contain citric acid and essential oils that can cause irritation and swelling in a dog's mouth and throat. Although unlikely, overconsumption of citrus fruits can lead to depression in a dog's central nervous system. It is important to exercise caution and only offer small amounts of citrus fruit to your pet, as even small doses can result in an upset stomach. It is recommended to choose dog-friendly treats that do not contain harmful ingredients, such as citric acid, to ensure the continued health and well-being of your furry friend.



  Coconut and its by-products, including coconut oil, can be safely consumed by pets in moderation. However, it is important to exercise caution as the consumption of fresh coconut milk has been known to cause digestive upset, such as loose stool and diarrhea, in some animals. Therefore, it is recommended to proceed with caution when offering coconut-based products to your furry companion.

9- Grapes


 Grapes and raisins pose a serious threat to the health and well-being of our canine friends, as they have been shown to cause kidney failure in dogs. Despite ongoing research, the specific compound responsible for this toxic reaction remains elusive to scientists. It is imperative that pet owners take necessary precautions to prevent their dogs from accessing grapes and raisins. This includes storing them securely and out of reach, and seeking immediate veterinary attention in the event of suspected ingestion. The risk of toxicity cannot be underestimated, as even a small amount of grapes or raisins can have severe consequences for a dog's health.

10.Macadamia Nuts

   Macadamia nuts may be a delightful treat for humans, offering a taste of Hawaii's tropical paradise, but they can be extremely toxic to our furry companions. The ingestion of macadamia nuts can lead to a range of negative symptoms in dogs, including limb weakness, vomiting, depression, tremors, and even hyperthermia. These symptoms can manifest as quickly as 12 hours after consumption and may last for up to 48 hours. It is crucial for pet owners to be aware of the dangers posed by macadamia nuts and to take necessary precautions to keep them out of reach of their dogs. In the event of suspected ingestion, immediate veterinary attention is strongly recommended.

11.Dairy Products

   Our beloved canine and feline friends lack the necessary digestive enzyme, lactase, to properly break down significant quantities of lactose, found in dairy products like cheese, sauces, and milk. This can result in digestive distress such as diarrhea and vomiting. As a responsible pet owner, it is important to be aware of the impact of dairy on your animal's health and to avoid offering dairy-based products as part of their diet. By providing a well-balanced and nutritionally appropriate diet, you can help ensure your pet's overall well-being and avoid any adverse digestive reactions.


   As responsible pet owners, it is important to be mindful of the foods we offer our furry companions, and nuts should be avoided entirely. While peanuts may seem like a common snack for dogs, it's important to note that they are actually legumes and not nuts. On the other hand, nuts such as almonds, pecans, and walnuts contain high levels of fats and oils, which can lead to pancreatitis when consumed in excess. These high-fat content foods can cause digestive upset such as vomiting and diarrhea in dogs, making them a potentially hazardous addition to your pet's diet. By being mindful of the foods we offer our pets and ensuring a well-balanced and nutritionally appropriate diet, we can help promote their overall health and wellbeing.

13.Onions and Garlic

   Plants belonging to the Allium family, including onions, chives, and garlic, can pose a significant health risk to both dogs and cats, particularly with long-term exposure. The consumption of these vegetables can result in gastrointestinal irritation, which if left unchecked, can lead to the damage of red blood cells and even anemia. Our feline friends are particularly susceptible to the negative effects of these veggies, and even a small amount can cause significant illness. For dogs, overindulgence can also result in adverse health effects, making it crucial for pet owners to take measures to keep these plants out of reach. By being mindful of the foods we offer our pets and providing a well-rounded, nutritionally appropriate diet, we can help promote their overall health and wellbeing.

14.Undercooked Meat and Eggs

   While it may be tempting to believe that our canine companions, descended from wolves, are capable of consuming raw meat and eggs without issue, it is important to consider the evolutionary changes they have undergone. 

Over time, dogs have lost many of the processes that once allowed them to safely consume raw foods. Raw meat and eggs can potentially harbor dangerous bacteria such as salmonella and E. coli, which can rapidly infect a dog's digestive system and cause severe illness. Additionally, raw eggs contain an enzyme called avidin that interferes with biotin absorption, potentially leading to skin and coat problems if consumed regularly. To ensure the health and wellbeing of our furry friends, it is essential to provide them with a balanced diet free of raw meat and eggs and to take necessary precautions to prevent exposure to these potentially hazardous foods.

15.High-Sodium Foods

    The dangers of excessive salt intake for dogs cannot be overstated. Salt, a common ingredient in many human snacks such as pretzels, potato chips, and popcorn, can lead to sodium ion poisoning in dogs and cause a host of negative symptoms. When dogs consume large amounts of salt, they may experience excessive thirst and urination, diarrhea, vomiting, depression, elevated body temperature, tremors, and in severe cases, death. It's important to avoid feeding your furry friend these salty treats to prevent the risk of sodium ion poisoning.



   The sweetener Xylitol, whether it be synthetic or natural, is widely used in various products to enhance their taste and sweetness. From baked goods and candies, to gums and toothpastes, Xylitol can be found in many common items. However, what may seem like a harmless treat to us, can be extremely hazardous for our beloved furry friends. Ingestion of Xylitol can lead to the sudden release of insulin, causing liver failure and hypoglycemia in dogs. The effects can be severe and include symptoms such as vomiting, loss of coordination, lethargy, and even seizures. Time is of the essence, so it is crucial to seek veterinary care as soon as possible if your dog has consumed any products containing Xylitol.

17. Yeast

    As a pet owner, it's important to be aware of the dangers of certain foods that might be commonly found in your kitchen. One such substance is yeast dough, which has the potential to cause serious harm to your furry friend.

   Yeast dough contains live yeast cells that can continue to ferment and produce carbon dioxide in your dog's digestive system. This process can lead to bloating, a condition where the abdomen becomes distended and filled with gas. In severe cases, bloating can cause the intestines to twist, which can lead to a life-threatening emergency.

   Therefore, it is essential to keep yeast dough and baked goods that contain yeast away from your dog. Raw bread dough and bread raised using yeast should also be avoided as they can cause the same effects in your pet. It's always best to err on the side of caution and keep harmful substances out of reach of your furry friend.


   In conclusion, it's essential for pet owners to be aware of the human foods that can be harmful to their dogs. Our furry companions rely on us to keep them healthy and safe, and by understanding which foods to avoid, we can ensure that they are protected from potential harm. Foods such as alcohol, avocado, bones, caffeine, candy and many others should be avoided or limited under veterinary supervision. Remember, a balanced diet and proper nutrition are crucial for the well-being of your pet. Keep your dog healthy and happy by offering them the right foods and avoiding those that may pose a threat to their health.
