dog has been having diarrhea for past few days?

my dog swallowed a bone 4 days ago. that night she began having diarrhea. the next day she threw up her food. she was then acting lethargic for the rest of the day. she was also acting like she had to poop but wasn't able to. she would strain then walk and strin again. she did this all day. we started her on the rice diet the next day. we also noticed the next day that our other dog was having diarrhea. my dog that ate the bone was also having the pooping issue yesterday and a little bit today. I read online that if the bone was blocking her from pooping then she would be throwing up and acting lethargic. but after that first day of really being sick they were both acting fine but still having diarrhea. my dog that ate the bone was just bleeding after either trying to or having diarrhea.
