I intentionally shot my neighbor's dog, and I mean intentionally.
The poor dog! Why would you do that? What were you thinking?
I was mad and I had my gun and I felt like shooting
That's a terrible thing you've done!  You should own up to it immediately and prepare to turn yourself in.  People go to jail for murdering other people's pets!
I didn't necessarily kill the dog, I just shot it.
Shooting it could kill it, or it could lead to lifelong health complications, pain, and crippling vet bills. Even if the dog survived, that was so cruel you should look into anger management therapy. You shouldn't hurt anyone, animals or people, for no reason just because you're mad.
