A dog breed specifically designed to hunt down and kill snakes is one option.
Those who reside in nations with a high concentration of poisonous
snakes or in regions plagued by snakes would do well to consider this.
Most dogs aren't snake hunters because they weren't bred to do so and because they aren't taught to do so.
Just so you know, none of the dog breeds listed here are good at hunting snakes or killing them.
In its place, you'll have a companion who, should you ever encounter an angry snake, will gladly take a bullet for you.
I should emphasize that if you take your dog to the vet right away after a snake bite, about 95% of them will live.
