Thanks for the imput y'all.
I thought of rabbits, a jack rabbit maybe.
His shrubs are pretty thick, I was thinking something like beaver

, well, no I guess not around here.
I thought rabbits ate soft stuff like leaves. I guess if they're hungry they would eat the bark too. There must have been a whole herd of them because he's got a lot of shrubs and it happened over nite.
I guess I was thinking of something a lot more mysterious for around here.
If you get to thinking you're a person of some influence, try ordering somebody else's dog around.
