9 Common Foods Dogs Cannot Eat

Especially dark chocolate and chocolate based foods, they contain a large amount of theobromine and caffeine, which are toxic to dogs. Cocoa alkaloids and caffeine belong to the methylxanthine class of compounds, which can stimulate the central nervous system of dogs, causing increased heart rate, vasodilation, smooth muscle relaxation, and diuresis. Dogs' bodies are unable to effectively metabolize and eliminate these substances, so even consuming small amounts can lead to poisoning.

Onions and garlic contain harmful substances to dogs - n-propyl disulfide. This substance can oxidize hemoglobin in dogs, damage red blood cells, and cause hemolytic anemia symptoms such as loss of appetite, vomiting, and diarrhea. In severe cases, it may also cause urine to appear light red or brownish red. However, consuming in small quantities usually does not cause serious harm. If a dog accidentally eats a small piece, the owner doesn't need to worry too much.

Grapes and grape products contain harmful substances to dogs, which can accumulate in their bodies and cause serious damage to their kidneys. Most dogs experience symptoms of acute kidney failure shortly after consuming grapes, such as decreased urine, dehydration, and excessive drinking. In severe cases, these injuries may endanger the life of the dog.

Chicken bones and broken bones may stab a dog's throat, damage the esophagus and gastrointestinal tract. So, please do not feed bones directly to dogs after consuming chicken, especially small broken bones.

Some pet owners, out of curiosity, may feed their dogs alcoholic beverages, but this behavior is extremely inappropriate! Any alcoholic beverage should never be given to dogs, as alcohol can affect their central nervous system, causing them to become excited first and then suppressed, which may lead to symptoms such as vomiting, restlessness, frequent urination, and abnormal behavior. If excessive alcohol intake occurs, dogs may also fall into dangerous conditions such as coma, difficulty breathing, and heart rate suppression.

Liver is one of the favorite foods for dogs, and many snacks and dog food contain liver components. Moderate consumption of liver is beneficial for dogs, but excessive intake may lead to nutritional imbalance. This is because the liver contains a high amount of vitamin A, and excessive intake may lead to vitamin A poisoning or vitamin A excess syndrome.

Many fruit kernels, such as apples, cherries, and apricots, contain cyanide. If dogs accidentally chew or bite these fruit pits, cyanide will be released. Cyanide is an extremely toxic substance that can interfere with cellular respiration in dogs, causing cellular hypoxia and leading to poisoning. The symptoms of cyanide poisoning may include shortness of breath, vomiting, changes in blood color, convulsions, and in severe cases, can even be fatal.

Raw protein contains a protein called ovalbumin, which consumes vitamin H (belonging to the vitamin B group) in dogs. Vitamin H is crucial for the growth and fur health of dogs. Raw eggs may also contain bacteria such as Salmonella, and long-term feeding of raw eggs may lead to toxin intake and trigger vitamin H deficiency.

There are numerous parasites and bacteria hidden in raw meat, which pose a serious threat to the health of dogs. So, if you need to feed meat, be sure to cook the meat until it is 80% cooked to ensure the safety of your dog.
