My boy is back at the vets again I'm afraid.  Frightening experience.  Took him for his walk yesterday morning, gave him his usual food for breakfast.  I noticed that he wasn't quite himself and later in the morning he had to go out and his poo was just slime and he subsequently had watery diarrhea for a couple of hours and was sick.  He drank lots of water so I wasn't too concerned.  I kept him off food for the rest of the day and noticed that there were one or two spots of blood in the poo but he didn't vomit again.   In the evening he didn't need to go to the toilet.  We heard no sound from him during the night and when I came downstairs there were signs that he had been sick a little. I took him outside for a walk and his demeanour was very poor.  His poo was a little better formed but still very loose but no blood.  Brought him into the house turned my back on him for a moment and then noticed a puddle of blood on the floor.  I didn't know which end it came from.  Then he did it again, he was passing a large amount of blood.  Straight to the vet waiting for her to arrive.  His temperature was normal - demeanour terrible.  I relayed exactly what had been happening.  She asked about the colour of the blood.  Oscar thought he'd help me out and promptly showed her leaving a terrible mess (he'd already passed another load of blood outside the vet).  He is now on fluids (passed blood again when I left) and has been given 2 anti biotic injections.  I am ringing every two hours.  Desperately worried about my little boy and what on earth caused it.  Missing him terribly.  Vet hasn't heard of any other cases like this recently.

Our Maltese had exactly the same about 18 months ago it was really scary. When we got up in the morning it was like a blood bath our dog was hardly alive we managed to get her to the vets and she was immediatly put on a drip. She stayed at the vets for a few days but was ok in the end. It sounds like you caught your dog before things got too bad and i wish him a speedy recovery. I have my fingers crossed for you both.

He`s in the best place & you`ve gotten him speedy treatment so that should go a long way in getting him better quickly, ;) Let us know he gets on.

Thanks for those kind words.  Vet called to say that I take Oscar home last night. His blood test didn't reveal anything unusual so no clues there.   He seemed a lot brighter.  Still passing blood in the evening but I called the emergency vet and she said that this was probably to be expected with such an acute case.  Went down to him at about 4 am this morning and he had been sick.  He slept on me for a couple of hours and I gave him a bit more food with added water.  He now looks a lot more like himself.  Been out for a short walk and only wees which I hope is good news.  Back to the vet at 11 am for a follow on check up although she did say that if I was worried at all I should turn up on the doorstep like yesterday morning. 
I still have no idea what has caused this and where it happened.  I don't even have a short list of things it might have been.

Thinking about you both. We had a similar week with Sparky, though not as severe as this, by the sound of it. Like you, I've been given no explanation of what it is or what caused it, other than "dogs do tend to forage and he's probably eaten something". Hope your little one is OK.

Oscar appears to have made a complete recovery and has just finished his course of antibiotics.  He will be kept on the lead more until he can be trusted not to pick up and eat things on his walks.  The acuteness of the illness led the vet to think that it might have been a poisonous plant or mushroom but we just don't know. On the park where we go, people have been saying that some dogs have been catching rabbits which is very unusual as they can normally out-run a dog.  There's a possibility that the local rabbit population has got some sort of virus and Oscar is a devil for eating rabbit droppings.   He is still very young so I am hoping that he grows out of the habit.  The event also re-emphasises the need to get a poorly dog to the vet a.s.a.p. because they can go down hill rapidly especially if they haven't had much water. The difference within a 2 hour period was incredible.   Thanks for the good wishes.  This particular crisis seems to be behind us now.
