Dogs have been loyal and useful companions for humans through the ages, providing physical and emotional security as loving pets.
There are about 400 million+ dogs in the entire world.
The average life of a dog depending on the breed can vary from 10 to 14 years.
Due to their amazing sense of smell, dogs are capable of differentiating and recognising odours. For this reason, they are used to sniff out drugs and weapons by anti-terrorist squads and police departments all over the world.
