I'm going to let my dog pee on an outdoor plant pot
What will your dog peeing on an outdoor plant pot do?
The plant might die but other than that, nothing should happen.
You should learn to curb your dog. The plant pot is not your belonging so you should not left your dog pee on it. It is rude and disrespectful and if the plant dies you can be cited for property damage.
Don't you think that my dog should be prioritized than a mere plant?
It is just the fact that the outdoor plant pot is not yours. If that was your plant and you saw someone allowing their dog to pee on it, I am sure you would be upset about it.
