Evnin, up here in Canada we have burrs, pich forks, and some other weed similar to that. Grows around dried up beaver ponds. The very first time I took my GWP pup Diggzz out we weren't 10yds from the truck and he sees a big clump of burrs and being curious he bee lined over to it for a closer look. Took me 10-15 minutes to get his ears apart. Wondered what I'd gotten myself into??? Still miss him big time! Bill out. πŸΎπŸ‘£πŸΎπŸ‘£πŸ‡¨πŸ‡¦
