My dog just died an hour ago. He is 9 years old was strong, healthy, and happy. He threw up once last night and earlier today he was jumping around acting perfectly normal. At 1 am I heard him throw up again so I went to check on him. He had a mixture of foam and saliva hanging from his mouth. He drank nearly a gallon and a half of water on a period of an hour, throwing up three times in that time period and it was all clear. We comforted him and stayed with him. He was delirious and barely coherent he eventually started breathing hard and he got up walked outside and collapsed. Minutes later he had a seizure and a couple of convulsions and died in my arms. Please if you know anything about this write back. We have other dogs and need to know of they will be ok
