Why do people hang blue bottles outside the house, does it keep dogs away?

Blue Bottles Outside House For Dogs: For some time now, one thing has been seen a lot on social media. Many people are calling it a belief. Many people are calling it superstition. Many people are giving the logic of science behind it. These days it is being seen that many people are hanging blue bottles outside their houses.

People are filling plastic bottles with blue color mixed in water. And hanging them outside on the doors or with the support of the wall. People believe that dogs do not come near the house due to this blue color. They run away after seeing it. And there is no dirt around the house. But does this happen? Let us tell you.

Does the color blue be more visible to dogs?

People hang blue bottles outside their houses because it keeps dogs away. The reason behind this is that dogs can see blue more clearly than other colours and that is why they feel that there is some danger there. Because of this, they do not go near the bottle. Because of this, there is no dirt outside the houses. And because of this, many people are adopting this thing these days and are hanging blue bottles outside their houses.

Science says something else.

People say that dogs can see blue color more and it is a danger sign for them, because of this they do not come near the house. But if we believe in science, then science says that dogs are color-blind. That is, they are unable to differentiate between colors. That is, there is no scientific basis for the fact that hanging a blue bottle will keep dogs away from the house.

Many people also hang red colored bottles

Not only this, people are hanging only blue-coloured bottles outside the houses for dogs. Red coloured bottles have also been seen hanging outside many houses. Those who hang red-coloured bottles have the same belief as those who hang blue coloured bottles. However, there is no concrete evidence that dogs will not come near any coloured bottle, be it blue or red.
