The verb �go � can be used this way.
But it should be �The cow goes Moo � (not Mow)
There �s a whole children �s song
Cow goes moo moo,
horse goes neigh neigh
cat goes..... etc
And there �s the Trolley Song, with Ding Ding Ding goes the bell.
The horn on the bus goes �Beep Beep Beep �
There is even a tendency for young persons [ not me ;-) ] to use go instead of say, which I think sounds terrible, but you get used to it. I suppose that �s how the language changes.
eg: He goes � What did ya do that for? �
We usually ask � What does a cow say? �
or
What sound does a cow make?
