Park Slope Dog Kills Area Tree?

It's not the dog poop that kills trees; it's the dog urine. From "The Straight Dope":

...dog urine can cause grass, shrubs, and other plant life to turn brown and wither. This charming phenomenon is called "urine burn." It's caused by the ammonia and urea contained in doggie water (and, for that matter, in the urine of all mammals). Urea and ammonia are both good sources of nitrogen, an important fertilizer. But they're simple compounds and they break down so quickly that the lawn, hedge, or whatever basically ODs on the stuff.

Just like buttering toast, eh Rico? Man, your shoes must stink like the stank.

Baloney!

My dog has a very specific area in the yard designated for his business.

Everything in that area grows faster bigger and greener.
I have never seen dog piss kill a tree.
It would take gallons of the stuff.

Those pushpins are more harmful.

Geez how would these whiners fare in NYC a hundred years ago when horses crapped everywhere?

Ugh, dog lovers or better yet, dog owners.
crap on them.

whizzer, you don't know what you're talking about. it doesn't take that many repeated urinations to burn trees but it would take hundreds, if not thousands, of pins to sufficiently lacerate the cambium layer to cause any damage to the tree. the poo, however probably is not doing any harm. to the tree.

"Ricco Starr" You scoop your dogshit up and place it in the trashcan dumbass! This is because lazy owners don't take the time to properly clean-up after there pets .
