In September my 110lb doberman, ate a box of these chews. When we took him to the emergency clinic they didn't give him water and just put on IV, telling us that in the morning we could bring him home. My dog never came back home. I went back to amazon, to read reviews and found that another dog died from them earlier. I left my comment there, and since I have received two more comments from other users that their dogs died too. So in the short time there are 5 dogs died, and I am sure there is many more whose owners do not write. Vets seem completely unaware that glucosamine could cause liver failure. Why no study is done about it? Where do I need to write to stop selling of this product? Our dogs are in real danger.View Thread
