Walking in a far area of the UCD arboretum recently, my dog Tyler suddenly yelped, began to whine, shake his head, and favor his left ear.
Looking, I saw we had come to a small area of foxtails and he had apparently gotten one in his left ear. We took him to a vet immediately. Sure enough, a foxtail was lodged deeply in that ear. Fortunately, it could be removed and he is fine now.
That episode has made me alert to the presence of foxtails and I have begun to notice that a great many Old North properties feature them next to the sidewalks and along the alleys and some streets.
