Issues caused by cheatgrass
If a dog inhales cheatgrass, it can go down the esophagus and will likely be digested. However, if swallowed and it makes its way down the trachea, it can become a migrating foreign body. That foreign body can then make its way to the heart, lungs, or abdomen and become an abscess.
Signs of a possible cheatgrass abscess
Hard swallowing, coughing, or gagging.
