     When I was six, Dad brought home a dog one day, who was called "Brownie". My brothers and I all loved

Brownie and did different things with her. One of us would walk her, another would feed her, then there were

baths, playing catch and many other games. Brownie, in return loved each and every one of us. One thing that

most touched my heart was that she would go to whoever was sick and just be with them we always felt better

when she was around.

     One day, as I was getting her food, she chewed up (咬破) one of Dad's shoes, which had to be thrown

away in the end. I knew Dad would be mad and I had to let her know what she did was wrong. When I looked

at her and said, "Bad girl," she looked down at the ground and then went and hid. I saw a tear in her eyes.

     Brownie turned out to be more than just our family pet, she went everywhere with us. People would stop

and ask if they could pet her. Of course she'd let anyone pet her. She was just the most lovable dog. There were

many times when we'd be out walking and a small child would come over and pull pm her hair. she never barked

(吠) or tried to get away. Funny thing is she would smile. This frightened people because they thought she was

showing her teeth. Far from the truth, she lovely everyone.
