Garden toxins or medicines. Do the garden and backyard check! Flowers, plants and herbs can help you dog or harm your dog. How to know which are good and which are not.
Here are some of my own and my friends experiences listed. Sometimes my Dogue de Bordeaux, Samson, is like a cow. He eats grass and greens in the backyard, he meditates under plants and chills for hours in the grass on the same spot. He taught me that some plants can help dogs to feel better with some health issues.
