I'm going to the HOA about my neighbors dog.
What did their dog do?
I'm going to go and show the board my neighbor's dog's poop.
Going to the HOA over a trivial matter like dog poop from your neighbor's dog makes you look weak and immature. Talk to your neighbors about it directly instead.
They never do a doggy poopy patrol like other neighborhoods. Maybe they don't even know!
The HOA is going to start to dislike you if you go to them with things like this. Talk to the neighbor and work it out yourself.
