three cows and one bull

One day i walked in the forest and suddenly i saw a cow. I said to the cow: 'he, dheno!' This is the grammatically correct form to address a single cow in sanskrit. But the cow was not impressed and continued to graze by the the side of the road. A moment later i saw a second cow. I said: 'he, dhenuu !!' This is the grammatically correct form to address two cows in sanskrit. But both cows were not impressed and continued to graze silently by the the side of the road. Some time later I saw a third cow. I said: 'he, dhenavah !!!' This is the grammatically correct form to address three or more cows in sanskrit. But all three cows were unimpressed and continued to eat the green grass by the side of the road. The next day I saw a bull in the forest. I said: 'he, gau!' This is the grammatically correct form to address one bull in sanskrit. The bull stopped grazing, turned his had, looked at me, opened his mouth and said loud and clearly: 'Om!' Then he closed his mouth again and returned his attention to the grass growing at the side of the road. Another day I went for a walk into the forest and suddenly I saw a furious black dog coming towards me from one house barking at me. I said: 'he, shvan!' This is the grammatically correct form to address one dog in sanskrit. But the dog continued barking and exposed his teeth. So I reached into my pocket and brought forward some biscuits. As the black dog barked louder, threw one biscuit towards the dog. The dog immediately stopped barking and ran for shelter, as if I had thrown a stone at him, not a biscuit. I picked up the biscuit, held it for one moment into the air and then put it down on the ground and walked away. The dog came closer, sniffed suspiciously at the buiscuit and swollowed it up. The next time he saw me, he didn't bark at me anymore.
