Report animal abuse?

Good day,

I have a small problem. Weeks ago, I reported to my local veterinary office that my neighbor keeps a Labrador bitch on a chain in his backyard and only takes her for walks in exceptional circumstances. She also had a broken leg that wasn't treated medically, so it healed crookedly and the dog has been in pain ever since. I consider this animal abuse, and I've asked my brother to report this case to the veterinary office. They've already received two reports regarding this incident, but nothing has happened. That's why I wanted to ask where else I could report it, because everywhere it says you should notify the veterinary office, but they do absolutely nothing.

Thanks in advance 🙂
