Vedic civilization gives protection to all the living creatures, especially the cows, because they render such valuable service to the human society in the shape of milk, without which no one can become healthy and strong. In your country the dog is protected, and the cow is killed. The dog is passing stool and urine in the street, he is considered the best friend of man, and the cow is all pure, stool, urine, and milk, but they are taken to the slaughter house and killed for food. What kind of civilization is this. Therefore we have to preach against all this nonsense.
