It is not normal after they are dewormed to have watery, jelly bloody stools. Ideally, contact your veterinarian regarding the use of the metronidazole if you have some at home. Having said that, at a prescribed, recommended dose, metronidazole is often quite effective at getting the stool back under control. However, there could be additional things going on that need to be addressed. She is quite young; if she has any additional symptoms (inappetence or vomiting, lethargy, not playful) please take her to a veterinarian as soon as you can. She may have parvovirus, or another serious ailment. Thank you for using Petco Pet Education Center, formerly Petcoach!
