It may be that the dog urine is concentrated enough to burn the roots of the tree. About the only thing you can do is flood the area at the base of the tree to help dilute the urine. Do this once a week and it may help. Curled leaves can be a sign of insect or disease problems. I'm more inclined to think aphids are the culprits. Closely inspect the curled leaves - you may see aphids feeding or their cast skins (white flakes). If so, that's the cause.
