Every time we walk in the woods, my dog pulls up & eats this plant. She is not interested in grass or any other plant - just this one. It doesn't seem to be harming her but is it medicinal or does it just taste good?
your dog's favcourite plant is Galium aparine - which has many common names - Goosegrass, cleavers or Sticky willie the most often used. It has little hooks on the square stems and leaves as well as on the little paired ball like fruits all of which can cause it to stick to clothing and fur. My friends chickens quite like it and i don't believe its poisonous but I've no idea why your dog likes it so much.
