The Day Bul-bul Passed Away

I have a sad story in my life. I would never forget that moment. About 5 years ago, I had three dogs. I always have dogs since I was 7 years old because I love dogs a lot. At that time, I had two male dogs and female one. I called them Cokie, Gembul, and Bul-bul. Bul-bul was still a baby, about 3 months. I liked him very much. He was very nice and friendly. He had brown and thick fur. He was fat but active. He was very adorable. I like to play with him. I really enjoyed spending my time with him.
Until one day, on a beautiful morning a tragedy happened. As usual, when morning came my dad was going jogging around our neighborhood. When he walked to our gate, he found our three dogs lied on the ground. They were all dying. Immediately, my dad called my mom and my brother. Because of the noisy voice I heard, I woke up too.
I was shocked when I saw all of them were dying. I cried because I didn’t want them to die. Then, my brother found that someone had poisoned them. Someone tried to kill my dogs. My brother found some mysterious powder in some chicken that they had eaten. We guessed someone put poison on it and threw it into our front yard and unfortunately, our dogs ate it. We didn’t know what his intention giving poison to our dogs was, but we assumed whoever did it was someone who hates dogs.
That was early in the morning, we could not go to the veterinarian. I held Bul-bul wit my arm and caressing his fur. He seemed very suffered and weak. I knew that he would die, but I couldn’t let him go. He was a very lovely, and I loved him very much. But, in a short time, he passed away in a very poor condition… I was very sad 
Fortunately, Cokie and Gembul could survive, they were alive. My brother said Cokie and Gembul survived because they were older than Bul-bul so they were stronger, but Bul-bul was just a baby, younger and weaker. This incident made me feel unhappy.
I was wondering why Bul-bul passed away so soon, why he left me. I still remembered the day before Bul-bul passed away. I had spent an afternoon with him. I remembered, I sat in a chair, I was reading comics and Bul-bul was next to me. He accompanied me. He sat near me. I never imagined that was my last time with him. That was the last time I could spend my time playing with Bul-bul.
Until now, I still feel bad about that moment. I always wonder what he looks like if he is still alive.
