It is true that dog's are man's best friends. Many people that have pets could confirm that, always telling that they have a great understanding with them so they love them really much. They often compare the friendship with human friendships adding that sometimes the animals could be even more thankful than people, showing their gratitude every time they can. That's why people are very sad when they lose a pet. When the dog dies, it is like a friend has lost his life and it is same in case that our dog disappears. Sometimes the animals leave their owners but sometimes someone else is responsible for their disappearing. There are people who don't care about the owners of the animal and they steal animals without having any regret while the owners of the animals feel like they've lost a friend. Willie had his dog Jeff for a certain period of time. Both of them managed to build an excellent relationship together and they loved each other very much. Unfortunately one day Jeff has disappeared, so Willie is very sad and worried at the moment.
