Each seed on the seed head is pointed at one end and has barbed “hairs” at the other. The pointed end can easily be driven into the dog’s skin by the pressure of passing through vegetation or undergrowth or can later travel through the coat and penetrate the skin by the general movement of the dog and the pressure caused by lying down or rolling. Due to the tiny hairs or barbs which are backward-pointing, the seed will not naturally drop out and
IT MAY TRAVEL AWAY FROM THE PENETRATION POINT TO ANYWHERE IN THE BODY!!
This action is facilitated by the barbs ... rather like a fish hook which goes in easily enough but is very tricky to get out!
Note the direction in which the barbs lie
ANSWER : CHECK YOUR DOG EVERY TIME YOU RETURN from an outing when it has been in or through areas of long or longish grass. This might seem tiresome, but it will be time well-spent and could save your dog a lot of suffering and you a lot of money (and suffering!!)
If you have a Newfoundland (as I do) you may have a blaster ... USE IT ... they are not just for wet coats, but should be used regularly on dry coats to rid them of dust, dander and .... grass seeds!!
If you have barbets you probably won’t have a blaster, but if you do, you can use it on a dry coat again, to blast out any debris (personally I wouldn’t recommend its use on a wet barbet coat), but in any case . . .
INSPECT and FEEL your dog all over; check for seeds especially the feet (between pads and toes), head, muzzle and behind ears, chest, fronts of legs, axillae and groin. If you suspect an embedded grass seed seek veterinary advice sooner rather than later!!
BEWARE and BE AWARE OF THE FOXTAILS !
