hi, i was just wondering if any one could off er any suggestions as to why my staff seems to be very poorly in the space of around 1 hr. he has been fine lively usual excitable self, he went very quiet he even turned cooked chicken down, then he vomited loads of brown fluid, my house has been extremly hectic this weekend full of kids and easter eggs!!!, nobody has noticed him eating chocolate i was just wondering if it was the chocolate what to do! he is asleep in front of fire just now but is still quiet!!! please help me thanks c.

If there is the slightest chance he has eaten chocolate, and is behaving as if he were ill, then I would take him to a vet ASAP.  Chocolate contains "Theobromine" with can be lethal to dogs.  Hope he is ok.
Dawn.
