Hi, is there any disease or parasite that can cause a dog to have bloody diarrhea the same day? I drove my friend to the animal shelter and she adopted two dogs today. When i left my dog this morning I left her a small bone to chew on and keep her busy while I was gone. I took her over to play with my friends new dogs three hours ago. She just had bloody diarrhea that smelled just like the shelter my friend rescued her dogs from. After going over there her dogs have runny diarrhea too.
