Are Black Snakes Poisonous to Dogs?

Black snakes are a common species of snake, but is their venom dangerous to dogs?

The short answer is that the majority of black snakes are not venomous, and their bites will not cause harm to dogs. However, it is important to know the species of black snake that you come across, as some may produce venom and could be capable of causing harm to a canine.

Types of Black Snakes

There are a variety of black snakes that are found in different parts of the world. The most prominent species of black snakes are:

  • Eastern Black Snake – Found throughout the eastern United States, these snakes typically grow up to 3.2 feet in length and can reach up to 5.8 feet. Eastern black snakes are non-venomous and are known to feed mostly on mice, but they can also eat birds and frogs.
  • Black Racer Snake – Native to North America, black racers are typically found in areas with swamps but they can also thrive in woodland regions. They can grow up to 4.9 feet long and feed on intermediate-sized prey. They are non-venomous.
  • Western Black Rat Snake – These non-venomous snakes are found in the western United States and parts of central Mexico. They can reach up to 6.5 feet in length, making them apart of the larger snake species. Their diet consists of small vertebrates such as rodents, lizards, and birds.

Are Black Snakes Poisonous?

Only the Black Mamba, which is native to Africa, is a highly venomous species of black snake. While there are a few other venomous species of snake found in Africa and other parts of the world, they are typically not black in color. So, while venomous black snakes do exist, they are rarely encountered and pose little to no threat to dogs.


In conclusion, black snakes are generally harmless and are not poisonous to dogs. However, it is always important to observe caution when coming across any type of snake, even one that isn’t venomous. Be sure to inspect the snake and know the species before approaching it.

If you do come across a black snake, do not attempt to handle it and allow it to move along on its own.
