Our ten month old border collie/boxer mix is having a great time eating our redwood trees that are about 10-12 feet tall.  Yes, she gets plenty of exercise and attention. I have staked chicken wire around the trees, but she is managing to bend it and still get to them.  She is given lots of toys/rawhides to chew, so I am at a loss.  Does anyone know if there is a product that you can spray on the trees, or wrap the trunks with to discourage this behavior?  She is with us most of the time, except at night. She gets hot in the house and would rather sleep outside.  This is when she is having fun with our trees!  help!

Both our lab mix & chi eat logs from the woodpile & sticks. So does the lab next door, & the golden on the other side, & just about every dog in our neighborhood ! I've never found a way to stop them. Maybe spray some hot sauce mixed with water on the trees ? My sil has 3' high chicken wire double wrapped around some of her trees to protect them from her dog & that seems to work too.
