Postal workers are often wary of dogs, as the animals often exhibit unfriendly behavior towards them.
The amazing fact is that dogs have their own logic that explains such strange behavior.
Any dog believes that it is obliged to protect the territory it lives in. This quality is characteristic of almost all representatives of the species.
If you live in a private house, then you probably know that the dog is unfriendly to almost all uninvited guests.
Therefore, there is nothing surprising in such behavior.
If the dog is trained correctly, then barking towards the postman will be "on duty". After a short time, the dog will calm down and continue doing its business.
Many people still subscribe to newspapers that are produced using special printing ink. Experts believe that the aroma of the substances in its composition is not to the liking of animals.
That's why the dog barks at the postman just because he doesn't like his smell.
