OMG! The same thing happened to my Star this week! She was very restless one night, pacing, salivating, circling then would lay down and definitely acted like she was not well. The next morning I found a HUGE matted chunk of upchucked grass on the floor! She was hacking and gagging on and off all day and when I fed her, she threw up her food less than a minute after eating. We went to the vet's and he said that her throat was severely excoriated from the grass and the gagging was due to the severe irriation and pain. He said her throat probably felt as sore as a fresh post op tonsillectomy patient. He put her on a bland, pureed diet, 4 small meals daily and Reglan, a medic. to ease the gag reflex and soothe the esophagus. She did great for one day. We have a huge backyard and while I tried to watch her the following day, apparently she ate more grass. That afternoon she had a bit of the runs then threw up some grass and green liquid Back to the vet's. He said her entire GI tract was severely irritated due to the grass. And all this in a dog with an iron gut, who just last month ate an ENTIRE chicken carcass without a burp! We use NO chemicals what so ever on the lawn so I know it wasn't that. Now she's on (in addition to the Reglan) Flagyl (metronidazole) and Hills ID Rx food for 2 weeks and only leash walking in the yard...she still wants to eat grass! Holly's symptoms sounded somewhat similar and perhaps this might be her problem too. I hope Holly's better soon It's so upsetting to see them under the weather and not know the reason why. You might want to mention Star's situation to your vet. Hope Holly's feeling better very soon. Hugs to you sweetheart. Sandra
