Q. My Jack Russell is vomiting profusely & has bright red blood coming out of her backside , she was well at 9:30am & came home @ 5:00. To find all this?
A. It could be that she is suffering from haemorrhagic gastro-enteritis which can start all of a sudden with a quite dramatic onset. You need to have her checked over as she can become stocky and deteriorate quite rapidly. She might need to be put on a drip. There are also other illnesses with the same symptoms but different causes, I am sure your vet will be able to help.
