My 11 month old female dane, Milah, has had some diarrhea lately so I tried the canned pumpkin thing with no change. After a couple days I had a fecal test done at my vet. It came back negative and they said they couldnt find any problem. And tonight the problem seemed to get worse. Me and my wife were sitting on the couch and she came up to us looking pittifull and then began to throw up. She threw up everything that she had eaten about 4 hours previous. Then she just went and laid down. I heard her stomach making some growling sounds so I took her outside to see if she needed to use the bathroom and she pretty much pooped brown water. After coming back in she threw up again and this time it was just what seemed to be left overs from the first time, nothing solid, just foamy liquid. Now she is laying on the couch and looks like she feels like crap. This has never happened before and I dont know what the problem could be. Any help would be greatly appreciated.
