Below is an email that I send my clients once a year. Hopefully it can help an owner prevent a foxtail from penetrating, or help an owner get the proper treatment.
Hi Karen,
This email is to let clients know that foxtails are becoming more and more prevalent as the grasses begin to die. Foxtails are the seeds that many of the local grasses leave behind when they die. They are sharp on one end, and the hairs on them only allow them to move in one direction. They can actually pierce a dog’s skin and can become a serious problem if embedded in the ears, nose, stomach, etc., and even when embedded in the paw. Foxtails can become embedded in the skin, and can work their way through the body until they come out of the other side, or hit an impenetrable bone, ligament, etc. This can lead to bacterial and/or fungal infections, and can be very dangerous and even deadly.
I find that short-haired breeds such as Pit Bulls are much less likely to be susceptible foxtails in their coats, while breeds with a thick coat, such as German Shepherds, Akitas, Poodle mixes, etc. are much more likely to pick them up. Dogs can often pick them up in between the toes, on the nook where their upper hind legs meet their stomachs, and on their chest, as well as their nose and ears. I’ve had dogs in the pack who have had to have surgery to remove them after being embedded in the abdomen, ear, nose, and also paw.
