Well first, I had a dog. He was a really big dog, he was like, crossbred with a lot of big dogs. XD; He was a gentle giant and even if we sat down, he'd be taller than me. He belonged to my brother though, but I still treated him as my own. And one day my brother told me that someone threw something in the backyard and he went to go eat it and it was poison and he died. :(
Another dog I had, she didn't die, but we had to give her to the pound because she attacked another dog I had. And it was sad, she knew what she did wrong and when we were in the car riding to the pound, she just kept looking at me. But my parents already said I wasn't allowed to keep her anymore. And yeah.. Saddest trip I've ever had.
