Most types of fescue seed these days contain edophytes. These endophytes help the grass to resist disease and insects. However, endophytes can have detrimental effects on cattle, horses, and other grazing animals that eat endophyte-enriched grass. I know that many dogs like to munch on grass every once in a while. I was wondering if anyone knows how risky it is for a dog to occasionaly eat some of this grass? I have heard it can induce delirium in cattle and even still-births in horses.
