A traumatic history

I haven't got a traumatic history very serious. So i will tell when my dog lost. I was eleven or twelve years old and it was my first and only dog because I lived in a floor and cause my sister had allergy to animals'hair. I was very excited so i wanted a dog since i was little.
My sisters and me we saw an advertisement of a man that he gave dogs. He it was friends of my sisters and a day we went to his house to collected the dog. If the dog was male would be called Poncho, and if was female Vera. When arrived we saw three dogs, all males. We chose the most little. It was beautiful and my parents were happy althoug they weren't as excited as we.
It was inteligent, funny, obedient, nothing aggressive and very loving dog. Poncho it was the perfect dog and I don't say cause was mine.
When it was eleven months my sister opened the door and Poncho went out like other times, but this time it didn't come.
I don't know that happened only know that it was the better dog of the world.
