This morning I helped my neighbor remove the cactus barbs from his dog. He regularly takes his two dogs for runs up in the hilly desert area behind our subdivision. The poor pooch had a whole piece of jumping cholla stuck to his belly and several barbs on his legs and face.
. . . cholla cacti also known as “jumping cactus” it is notorious for very loose joint attachment, then the joints attach to hapless by-passers with the slightest brush.
