The danger of avocado lies in the skin, pit, and leaves of this fruit. They contain a substance called persin that can be very harmful to dogs. The flesh of the avocado, on the other hand, is harmless.


Another fruit that seems completely healthy and harmless but is considered a prohibited food for dogs due to its toxicity. Grapes and raisins can cause diarrhea, vomiting, and even acute kidney failure in dogs.


The caffeine and theine in tea and coffee are stimulants that dogs do not tolerate as well as humans and can lead to increased blood pressure, heart arrhythmias, or rapid heartbeat. While it’s not common for someone to offer coffee or tea to their dog, it’s good to know that it is a harmful food for dogs.


Milk, cheese, yogurts… Although puppies may consume milk, as dogs grow older, their ability to digest lactose decreases due to the loss of lactase enzymes responsible for this process. This can lead to abdominal discomfort, diarrhea, or vomiting, so refrain from offering a lick of yogurt or a piece of cheese from your sandwich, as these are among the prohibited foods for dogs. It’s important to note that dairy products are also prohibited for dogs with kidney issues.


Macadamia nuts are toxic for dogs because of their high phosphorus content, which can cause inflammation, vomiting, and even fever in canines.


Unlike raw bones, cooked bones not only lose most of their nutrients but also become soft and can splinter, causing serious damage to the intestines or internal mucous membranes. Giving cooked bones to your dog can be fatal, so it’s strongly discouraged as it’s a dangerous food for dogs.


Artificial sweeteners like xylitol, found in sweetened foods such as peanut butter, candies, sweets, ice creams, and even toothpaste, are toxic and harmful to dogs.


Alcohol is harmful to both dogs and humans, but dogs’ kidneys do not eliminate alcohol from the body effectively. Therefore, it’s very dangerous for dogs.


Tomatoes contain glycoalkaloid and can cause diarrhea or vomiting in dogs, whether eaten raw or in sauces. It’s best to avoid giving your dog tomatoes as they are considered toxic foods for dogs.
