Human foods that dogs should avoid

Dogs need more care and treatment when they are on their period. Here are some foods you must avoid:


These fruits have a toxin named persin. Although they are safe for humans, it is very dangerous to the dogs. Persin is found in the bark, pits, fruits, and leaves of avocados, so do not give any portion of the fruit to the dog. Once dogs eat avocados, fluids get trapped in the chest and lungs. Thus, makes it hard for them to breathe, leads to oxygen deprivation, and can even cause death. Furthermore, the fluids can even accumulate in the abdomen, pancreas, and heart. This might lead to a fatal condition. The dog might swallow avocado pits which might cause blockage or choking.


It is a sweet alcohol substance mostly found in chewing gums, baking products, toothpaste, and sweet candies. Even though safe for us to consume, it is deadly for dogs. Consuming xylitol foods might significantly drop the blood sugar levels in the dog. Initial signs are shown within 20 minutes of the consumption. Some of the signs are weakness, seizures, coma, cannot move, depression, and vomiting. Moreover, if not treated immediately, can occur liver failure and even death.

Caffeine and Tea

Caffeine is mostly found in tea, cocoa, guarana, and coffee. At times it is added to medications and drinks. Caffeine will speed up the heart rate as well as rouse the nervous system of the dog. Within few hours of the consumption of caffeine, the dog will be restless. Plus, they will have no bladder control, diarrhea, extremely thirsty, and vomiting. Moreover, if they consume a lot of caffeine, then they might have lung failure or abnormal heart palpitation. This will lead to their death.

While humans can sometimes consume alcohol, but dogs cannot handle it, not even in small portions. In an hour of intake, you will see signs such as depression, diarrhea, smelly breath, low temperature, tiredness, vomiting, and lack of coordination. Hence, it will result in coma, seizure, lung failures, and in certain cases, death.

Yeast Dough

A dog should not eat the raw dough that has yeast. Once in the body, the cell ferment of yeast produces alcohol. Hence, the alcohol levels rise, which ultimately causes food poisoning and even death.

Furthermore, the dough makes the stomach bigger and causes extreme bloating. Thus, the other organs have more pressure making it the dog difficult to breathe.


Grapes, as well as raisins, are tremendously poisonous to dogs. This causes kidney failure, and if not treated immediately, then will cause death. However, which component in grape is toxic is still unknown. But even 1 – 2 grapes will make the dog sick. The toxic level varies for different dog breeds. But some reports state that dogs might die even after eating few raisins. Therefore, consumption of any amount means you need to go to the vet. Raw grapes or raisins and foods such as cakes and cookies containing them are harmful too. Some of the signs are depression, diarrhea, vomiting, and weakness. If not treated immediately, other signs are urinated less, extremely thirsty, and kidney failure.
