Culterra made dog very ill, no warnings on packaging!

We put Culterra Lawndressing on our lawn on small patches. Our dog took only one bite, then stopped as it probably didn't taste very good. She however still got extremely sick! Vomited black stuff during the night! Just got back from the Vet with a huge bill! Had to empty her gut and now she has intestinal inflammation which we have to treat with expensive medication. No where on the packaging does it state that it is dangerous for animals!!!! The packaging also says new improved formula and we think there is poison in there now, as we used it before without dogs getting sick! Stay away from this product if you care about your pets!!! I will contact them tomorrow when their offices are open. The public should be warned about this product!!!
