There’s a dog killer lurking in your neighborhood: a common weed, called foxtail. The many variants of the foxtail are not native to North America (with one exception), and many pet owners would gladly prescribe a Dantean punishment for the European immigrants—the Spanish in California where I live—who introduced the damned things to the New World. Native or not, chances are you see it every day during spring, summer, and fall and never think twice about it. But it’s out there, and if you don’t take appropriate precautions, it can kill your dog—or, at the very least, kill your veterinary budget. Here’s a story of one dog that came off second best in an encounter with the foxtail—but he lived. Others have not been so lucky.Article is from Leerburg.com
Good Luck hope it is not a Foxtail my motto is better to be safe than sorry.
