Paragraph: This morning the Spouse took Emily out for her morning squeeze . She 's reached a new phase in her dog - development : the sniffy phase . And this morning , as I 'd feared for some time , she sniffed in a foxtail . This is potentially life - threatening situation , as the damned things can get lodged in the dog 's twisty nasal passages and cause infections that can move into the brain and other squishy bits ( I ' ve heard rumors of foxtails moving directly into the brain , but I ' m not sure this is n't an urban myth ) .

Question: What may happen if my dog starts to sniff foxtail ?
It may start to develop health issues .
It may cause infections that can move into the brain.
