Should I try to do anything?

My neighbor has a dog and put him on like a pulley line so he can only run back and forth. OK fine, but quite often I hear him screaming at his dog telling him not do do things anymore or he will tie him to the ground so short he wont be able to move anywhere. Um, this animal is not a child and need to be trained. Screaming at it wont help because he doesn't understand. The other night I heard the dog yelping so loud like it was being attacked. I'm kind of concerned, but I'm torn between it being none of my business.

Just curious, what can you do? If someone would come to me to tell me what to do with my animal I'd send the person very far away...

What, exactly, is it you think you can/should do?
If you feel the animal is being abused, make a report - if it is just not what you think is right, but is not abuse, myob.

I suspect abuse is all. Just wondering what everyone else would do. I'm leaning towards minding my own business, but the sounds that animal makes at night are not right.

If he's physically abusing the dog it's one thing and you can report. I can't see yelling as an abuse in any way. Heck, I do yell at my animals too when they do something bad (like dogs stealing expensive cat's food or when my fat cat starts to knock the doors in bathroom for her own amusement waking up everyone at 5 am on weekend). They perfectly understand BTW, and quit right away.

Report that as factually as you can and leave it at that.

Have you spoken to the neighbor?

When a dog is tied out it is scared of being attacked because it can't really fight or run away. Many dogs get to letting out some awful yelps, begging to be out of the situation.

My neighbor actually ended up calling and they removed the dog form the home. I knew something wasn't right. Poor thing =(
