and Hordeum marinum (which appear across most of the western U.S.), though, are the grass species that cause the most harm to dogs (and other animals).

, Chenopodium album, Adonis luteola, Lotus hispidus, Trifolium angustifolium, Malva sylvestris,Plantagoalbicans, Plantagoserraria, Galium aparine, Calendula arvensis, Anagallis arvensis, etc.
These are seeds of several species of Graminaceae, most frequently Hordeum murinum
commonly named "wild barley" and Avena fatua or "wild oats"  that can be considered the major cause of grass seeds foreign body-related disease (GSFBD).

In 2014, the species cover in the control plot for both soil types averaged 36% medusahead, 16% yellow starthistle, 13% slender oat (Avena barbata Pott ex Link), 12% annual ryegrass, 6% ripgut brome (Bromus diandrus Roth), 6% soft chess, 4% hare barley (Hordeum murinum
I wouldn't volunteer to run my dog in it, but believe that the western issues are more often caused by "mouse barley," more properly hordeum murinum
, which has a much more aggressive structure.
It is about 8 Poaceae which are quoted certain species frequently ingested: Hordeum murinum
and Poa annua, 1 Typhacee Typha latifolia and 1 Cyperacees Scirpus sp, followed by family of Iridaceae represented by Iris pseudacurus, and family of Plantaginaceae by Plantago crasiifolia.
When the resection specimen was examined, a piece of wood was found in one patient, and a Hordeum Murinum
was found in the other.
