I went to my neighbor and told him to chain his dog up
Why did you ask him to chain up the dog?
Because the dog has growled at me before.
It is understandable that you would be concerned about an unchained dog that growls at passersby. It was good to talk to the owner; your request was reasonable. If he does not comply, you should consider calling animal control if you feel the dog is a danger to you.
I'm giving him a chance to do it but if he doesn't then I'm calling animal control.
That is fair of you. I hope it works out.
