My dog was shot. How can i stop dwelling on the past?

I had a cat once. This guy shot him one day while my dad and I were fishing. We found him in our yard with salt pellet shots all over. It was sad. At first I felt like you did. But then I got a new cat. A couple actually. Playing with a new pet will take your mind off of the pain long enough for it to subside enough for you to live happily. I still remember my cat. I think about him a lot. There are many times when I have reminders of him. But the way I feel about it is the same way I feel about my dead family members. I miss them, but they are gone and I'm still here so I have to live. Try it.
