Let me tell you a story about how I lost my dear dog .
First,I was taking him in front of my house. I was phoning my friend,when the dog saw a cat and ran after it.
Then I followed my dog but of course It was faster than me. I couldn't breath anymore.
After that, I found him barking at a tree where was the cat climbing.
Finally,I took my friend and went home. I was very tired after that!
