Yes you do. It's not normal to have blood in their stools/poop. Also dogs, like other animals, are very good at hiding when they are ill.
Your dog is drinking lots of water because he/she is probably dehydrated (lack of fluid) due to the diarrhoea and this can become very serious - so take your dog and get them checked out asap. The blood might just be because of the diarrhoea irritating the lining of the bowel, but still needs to get checked.
I agree with seeker ...get your dog to the vet.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
