Yesterday evening I put all the dogs outside for a while. I went out to check on them and I noticed Sydney was eating grass, there were also a couple very small areas where it looked like she might have thrown up but it looked like saliva. My dogs sometimes eat some grass and when I tell them no they stop. Well lastnight Syd would not stop eating grass, and she was eating it like a crazy women. She was literally running around trying to eat as much as she could, she wouldnt listen to me or come when i called her. I had to drag her way from the grass, and then she would fight me with all she had to go run back and eat more. The whole time her tounge was going in and out. I picked her up and put her in the screened in patio with me blocking the door way. She started frantically pacing non stop, couldnt relax and kept trying to bypass me so she could run to the grass and eat more. Finally I let her go and she ran back and was eating grass as fast as she could. this lasted about 30 min. Ive never seen anything like it, i have never seen a dog eat grass as urgently as she was, and she never threw up from it. Has anyone experianced this before, it was so strange I thought something was seriously wrong with her. She is ok now and hasnt done it since.
