I'm thinking of reporting my ex-friend to the authorities for animal abuse.
Is it because he's not taking proper care of his dog?
I'm worried about the dog's wellbeing.
If you own a dog, you need to take proper care of it. It's kind of you to intervene on the dog's behalf and report your ex-friend to the authorities. It's important to stop an abusive situation whenever you can.
Yes I am worried about the dog also because it is always trying to escape. It's probably doing that for a reason.
You are right on reporting the abuse. Those who own a dog should be more responsible when it comes to owning pets. Get the authorities to check it out thoroughly for that poor dog's sake.
