Foxtail alert! They are dangerous to dogs.

[LPC]

I have heard of this previously, but it is not always easy to supervise your dog 100% of the time when outdoors (e.g. on off-lead walks or in the garden - which Americans I believe call the "back yard"). However, it pays to be very vigilant and observe carefully what your dog is doing. The danger from foxtail ingestion is real.
