Can dog urine kill trees?

Urine does have quite a bit of urea, which is a type of nitrogen. Nitrogen is a very important plant food, but it’s concentrated – so it can burn plant roots. Usually it needs to be diluted with water. If you have dogs who have taken a liking to a tree, I would advise training them to urinate on a compost pile instead! The nitrogen helps to feed microbes that break down the compost.
