What is a Foxtail? And what do Foxtails look like?Foxtails—also called grass seed awns, mean seeds, timothy, cheatgrass, June grass, Downy Brome, or other local names—are an annual summer grass. They start growing in spring and are in full bloom by summer. They will then die during the winter.
Shaped like the tail of a fox, the tip has seeds arranged in spikey clusters with backward-facing barbs.1 The spikes and barbs allow for one-way burrowing, which is great news for the foxtail but bad news for dogs.
Where Are Foxtails Found?
Foxtails can be found anywhere in the United States but are most common in the West. They are most often found in these places:
Hiking trails
Parks
Flatlands
Meadows
Open grassy fields
While they are less common in urban areas, they can still be found in areas where grass is allowed to grow uncontrolled.
When the weather is warm, the foxtail dries out and hitches a ride on anything passing by, including dogs. This hitchhiking behavior is important for foxtail seed dispersal.
Foxtails can attach to any part of your dog’s body and start the burrowing process. This commonly includes:2
Eyes
Eyelids
Ears
Nostrils
Mouth
Spaces between the toes (in the paw pads)
In some cases, foxtails can burrow through the skin, finding their way into the spine or chest and belly cavities. Once inside, the foxtail continues to burrow, bringing bacteria and dirt along with it.
This can lead to much more serious conditions because internal organs may be affected. The foxtail will continue to cause problems until it is removed.
In some cases, advanced diagnostic tests and procedures may be required to identify and remove the foxtail.
What Are the Signs That a Dog Has Foxtails on Them?
If you live in an area where foxtails are abundant, here are some signs you can look for:
Head shaking
Limping
Pawing at the face
Snorting
Sneezing
Bloody nose
Excessive licking of an area on the body
Other signs can show up one to several days later. These may include:
Lumps
Bumps
Draining tracts
Areas of redness or tenderness
Inflammation
Lethargy
Depression
Decreased appetite
In the worst case scenarios, an embedded foxtail can make it to vital organs, including the lungs, spinal cord or brain, heart, and abdominal organs, causing symptoms specific to that organ. In very bad cases, surgery may be required to remove foxtails or treat infection resulting from embedded foxtails.
How to Remove Foxtails From a Dog
Early removal of the foxtail is important. If you live in a foxtail-prone area, ALWAYS check your dog after being outside.
If you see a foxtail on your dog’s fur or skin, you can attempt to remove it with tweezers.
If you are seeing any of the signs listed above or signs that a foxtail has penetrated the skin or entered an opening on your dog’s body, bring your dog to the vet. This includes the ears, nose, or mouth.
Trying to remove the foxtail yourself from a body cavity may result in an incomplete removal, with pieces of the foxtail still embedded in your dog’s skin and ready to burrow deeper. Foxtails can travel a great distance through body cavities, so it’s important that the full foxtail is removed.
How to Prevent Foxtails From Injuring Your Dog
There are a few ways you can avoid foxtails and keep your dog safe.
Dogs with long coats are more likely to pick up these annoying hitchhikers. Consider a trim for the summer to reduce the likelihood of attachment.
Working dogs, or dogs that spend a lot of time in tall grass, may be outfitted with a commercially available vest that covers and protects the chest and abdomen.
Avoid foxtail-prone areas to prevent injury to your dog.
Use a short leash when walking your dog.
If foxtails grow in your yard, make plans to remove them or call a landscaper for assistance.
Check for foxtails frequently and after periods of outdoor play, especially if you hike or spend time in foxtail-prone areas.
