Dogs against rodents

When I was young, I was surprised to hear what our neighbor in the province said that rats and mice are also afraid of dogs. That if you have a dog in your house then it will be free of rodents.

When we had our first dog, a ferocious female we named Jedi, I had witnessed how she not only chased by also killed the rats outside the house and mice inside the house of our rented home. The list of killings is long and the total would exceed 10. In effect, the house was pest-free when we left it for our new home.
