I've read some folks being a bottle of water on walks to dilute the pee so it's less likely to ruin grass. But in fairness if some dog pee is ruining grass, owners are not watering their lawns enough. There are plenty of dogs in my neighborhood that are walked and I don't think there are many pee spot issues.

But even better would be to not use grass :) uses too much water in the first place hehe

Plus for Nova, I've had it for years. I don't use it to it's fullest but it makes it so much cleaner and I can organize how I like
