Does putting a bottle of water on your lawn really keep dogs away?

Putting a bottle of water on your lawn is not an effective way to keep dogs away. Although there is a widely circulated belief that this method works by reflecting sunlight and creating a scary visual effect or by emitting a pungent or irritating odor to dogs, there is no scientific evidence to support these claims.

Dogs may initially show some curiosity towards the reflective bottle, but they quickly get used to it and the deterrent effect does not persist.
