Can I kick my dog hard if I have a problem?
What made you decide to kick your dog?
It had fleas and it wouldn't stop eating my food.
There is no reason to hurt an animal. This is dangerous behavior and your animal could really get hurt.
But I am so frustrated.
If you are so upset you feel the need to hurt the dog you should surrender or rehome it. Having a pet if a big responsibility and if you can't handle it let someone else, it is better for everyone.
