I live in rural Missouri next to my mother and father in law. They
own 4 goats that escaped from their pen, yesterday, and made their way
into my yard. Not necessarily a big deal, except for the fact that
they ate almost all of the bark off of a ~7 ft tall Douglas Pear tree.

Is there any way to save the tree or should I just accept the fact
that it will die, dig it up, and plant a new tree?

Thanks!
