D_Icon asked: I have to do a landscaping project for a friend and she has a small dog. I’m not sure what kind but it’s about the size of a terrier.
She (the owner) is a little older so I’m looking for low maintenance options like rubber mulch, maybe some colored rocks, etc.

CGH asked: I know that a lot of the wood chips/mulching is color treated, some have a bug repellent on them too. They may also contain some sort of anti fungal spray.
How can I use something like the pretty reddish wood chips in my backyard landscaping without risking my dogs health??
