Here's something everyone who huts with a dog needs to know about. It's a plant called foxtail. There are a bunch of different grasses under that name. Do a Google search on mean seeds and foxtail and you'll get a lot to think about. I know of several people who have lost dogs because of this type of grass. Unfortunately I've seen a lot of this stuff on state game lands around Pittsburgh the last couple years. There are whole fields of it mixed in with the sorghum. Especially on the Hillman State park game lands. I assume it's gaining a foothold in all game lands. This stuff is very dangerous for dogs. I've spoken to the game commission about this and they didn't know a thing about it till I brought it up. I don't know if they are going to do what is necessary to try to get rid of it or not. But the thing is if a hunter who doesn't know about this has a dog that gets sick because of foxtail the dog could die before it's diagnosed. What happens is that the individual seeds or awns have a small fish hook end and microscopic reverse spines that allow the seed to go forward but not back. It can enter a dog through the skin, eyes, nose, ears, or even genitals. It will travel through tissue leaving infection in it's wake. Seeds are very small and hard to see on x-ray or ultra sound. Take a look at the info on line and everyone should be contacting the game commission to demand they eradicate this stuff. I've also seen it on a hunting preserve yesterday. Check it out!
