Certain foods that are safe for humans can be harmful to dogs.

Because dogs have a different metabolism than people, feeding human foods to dogs can be very dangerous for their health and may even be fatal in some cases.


This article reviews seven food items that have been proven toxic to dogs—so if you have a dog, it's important to keep these foods out of their reach.

1. Avocados

Avocados contain a toxin called persin. Persin is perfectly safe for human consumption, but can be very poisonous to dogs (1).

It is found in avocado fruit, pits, leaves and bark, so you should avoid giving any part of the plant to your dog.

If a dog eats these, fluid may accumulate in the dog's lungs and chest.

This can make it difficult for him or her to breathe, which can lead to oxygen deprivation and even death (1).

Fluid can also accumulate in the heart, pancreas and abdomen, which can lead to other fatal complications (2).

Avocado pits can also be accidentally swallowed, which can cause choking or a blockage in the digestive tract.

Summary: Eating any part of the avocado plant can cause severe health problems in dogs that may result in death.

  • Exposure to phthalates was associated with autism traits in boys (but not girls) between ages 3 and 4 years, according to a new study.
  • However, the risk was diminished in women who took folic acid during their pregnancy.
  • This study is the first to find that folic acid supplements provide a protective effect from phthalates.
