Protecting Your Dog Against Foxtails
Dog in Foxtails

Tonight my littlest dog Nellie came in the house sneezing. Any other time of year and I would be unconcerned, but in late spring and early summer an abrupt onset of sneezing after being outdoors is a “foxtail-in-the-nose alarm bell.” I’ll be watching Nellie like a hawk for the rest of the evening. Any crinkling of her nose, ongoing sneezing or bloody nose, and she’ll be my first patient tomorrow morning.

If you are unfamiliar with foxtails, count your blessings! These pesky, bristly plant awns grow in abundance throughout California and are reported in most every state west of the Mississippi. Once the plant heads dry, they become hell-bent on finding their way into dogs’ noses, ears, eyes, mouths and just about every other orifice. They can dive deep into a dog’s nostril or ear canal (beyond sight) in the blink of an eye. And a foxtail camouflaged under a layer of hair can readily burrow through the skin (a favorite hiding place is between toes). Foxtails can wind up virtually anywhere in the body, and associated symptoms vary based on location. For example, a foxtail within the ear canal causes head shaking, under the skin a draining tract, or within the lung, labored breathing and coughing. Not only is the dog’s body incapable of degrading or decomposing foxtails, these plant awns are barbed in such a way that they can only move in a “forward” direction. Unless caught early, they, and the bacteria they carry, either become walled off to form an abscess or migrate through the body causing infection and tissue damage. Once foxtails have moved internally, they become the proverbial needle in a haystack—notoriously difficult to find and remove.

Take the example of Emma Louise, an undeniably adorable Brittany Spaniel mix whose family told me that her favorite pastime is running through fields with her nose to the ground. They described her as a “foxtail magnet,” having accumulated several in her ears and nose over the years. I was asked to help figure out the cause of Emma Louise’s hunched back and straining to urinate. With abdominal ultrasound, I discovered a gigantic abscess tucked up under Emma Louise’s spine, extending into her pelvic canal. Given this girl’s history, I just knew there had to be a foxtail in there somewhere. The question was, would we be able to find it?

As is my medical tradition before launching a foxtail search, I recited a prayer to the “god of foxtails.” I then turned Emma Louise over to one of my surgical colleagues for exploratory surgery. After two hours of nailbiting and a barrage of expletives originating in the O.R., I heard a shout of, “Got it!” The foxtail had been located and removed, and sweet little Emma Louise made a rapid and complete recovery. Not finding the foxtail would have meant a lifetime of antibiotics to treat her foxtail-induced infection.

If you suspect your dog has a foxtail-related issue, contact your veterinarian right away to find out what steps can be taken (at home or in the veterinary hospital) to rid your dog of this unwanted plant material. Whenever possible, avoidance of foxtail exposure is the best and only foolproof prevention. If your dog does have access to foxtails, carefully comb through his or her haircoat—checking ears and toes, too —a couple of times daily to remove any that are embedded and poised to wreak havoc!
