recently my dog has been vomiting and making herself sick by eating grass. Her faeces is also a red brick colour but then changes to normal colour.
any ideas?

Have you seen your vet Heather, I would also take a faecal sample. It may be merely a disagreement with her diet but it could be more serious, it is really a waste of time seeking a diagnosis over the internet as an examination will always be part of the process :)

hi there i can only agree with isabel, take your dog along to the vets just to be on the safe side, please let us know how you got on ,good luck and best wishes, sheryl
