Not long ago, we shared this image with you that identified the “antihelix” part of the ear (and to our immense satisfaction, a page friend reported using this term with her vet who was duly impressed). This time we’re adding to your ear vocabulary with the “lateral crus of helix” (seen with the blue arrow). We believe that an educated dog owner is a good dog owner, and honestly, isn’t it more helpful to a vet to learn from an owner that their dog’s “lateral crus of helix” is swollen than the more vague, “Uh, my dog’s ear is swollen.”
