I kicked my dog
Why did you decide that it would be the right thing to kick your dog?
I was overwhelmed by emotions and I can't stand his crazy behavior anymore.
You sound very overwhelmed. It is never acceptable to cause harm to a defenseless animal. It you can't take care of your dog, you should give it up.
My dog is crazy. I'm going to get a new one.
Just because you may feel overwhelmed does not mean that you should put those emotions onto your animal. When you feel that way, you need to find a healthy and safe way to release the feelings whether it is talking to someone, exercise, or something else. Hurting an animal that cannot defend itself is really sad.
