Here is a stupid or maybe not so stupid questions. I was wondering if there were any trees in the ohio area that are posionous to dogs. I make log cabin furniture and I just wondered. My dog is always getting something. I only ask because I was on another dog training forum and a man said his dog loves to chew on orcid tree leaves. I just happened to know that ever part of that plant is posion for dogs. So I thought I would ask this question.
