Thanks for using Petco Pet Education Center, formerly Petcoach! Bloody stools like that can happen from colitis for example which can be secondary to stress or an infection for instance. I recommend you have her evaluated by your veterinarian for further assessment and to start her on therapy. Most cases of colitis respond well to medications like metronidazole. Also, it is important to make sure she is not dehydrated as that can happen from repetitive bowel movements. Good luck and have a good day!
