Animals can become great friends. I once had a dog that I loved very much, and we where great friends, but the evil person who used to be my step dad killed him for no reason. When we buried him, I was too sad to even cry and it still hurts today when I think about my dog, Buddy. I guess I should tell how we found him:
This golden retriver showed up at my grandma's one day, and it was a nice dog. It stayed for a few days, so my mom decided to take him home with us. He happily came along, and when we got to the house, our two other dogs where chasing the cats again, and Buddy came up to the dogs and made them stop chasing the cats. Buddy was a cat lover, just like me. We only had him for about 3 months, but he's the best dog I could have ever had. I still miss him today even it's been 7 years since he's died.
