My Wiem almost dies last fall. I dont know what he ate but the first pile of puke had what looked like a paper towel in it. We keep the garbage in a cabinet so no clue where it came from. That started a Sunday night from hell, its always on the weekends. He puked up bile about every hour for the next 14 hours. About 10 hours in the diarrhea full of blood started. By morning he was puking blood too. Got him to the vet first thing in the morning and they kept him for 5 days giving him fluids and antibiotics. He finally ate on day 4 and I tried to bring him home but had to take him back after he started puking again. By the end of day 5 he was looking better and had eaten some so I brought him home and it was slow going for a few days but he came out of it. Very strange.
