I have Chihuahuas’ also. Maybe she is not getting enough fiber to bulk up stool. Notice how her stool is as opposed to your other Chi who does not have to have anal expressed. I feed Stella and Chewy’s . Now have my elderly mom’s Chihuahua also. She had loose stool when I would walk her . Since her diet change to what I have been feeding my two, her stools are normal. Hope this might help.
