my dog is having bloody diarrhea, it is mostly liquid. what is wrong? any at home remedies?

Just simple diarrhea wouldn’t be as serious a concern as bloody diarrhea. As the other person said, get that dog to the vet immediately. If your regular vet isn’t open or it’s after office hours then get the dog to an emergency clinic. It needs to be seen right away.

Best of luck to you and your dog!
