A quiet dog

When I go to buy bread on foot, there is a dog to always watch.
He (I don't know he or she. probably he)is kept in the house along a way.
Though looking powerful, he is very quiet.
Even if eyes match me, he keeps still with a blank face.
I never have that he was barked.
I went to buy bread on that day.
From the front, the man came with a big dog.
When they came near the house of a quiet dog, the man dashed suddenly.
He ran while dragging a dog.
I heard a scathing bark immediately.
"Woof woof".
The dragged dog did not bark.
It means that the quiet dog barked.
Because the man understood it, he would dash.
Then, I go along in front of the quiet dog.
I went with a feeling fearfully.
The dog was quiet with a blank face.
I felt relieved.
You are a nice dog.
But I have watched your hiding part.
