Help! I have a female French Bulldog who is 5 years old. She is dropping poop marbles in the house one to two times a day, sometimes every other day. Sheโs had a spinal X-ray which her vet said it showed a underdeveloped vertebrae on one side. She then had a MRI and Spinal tap done which came back as being fine. Said the underdeveloped vertebrae is common in French Bulldogs and not a problem.We then changed her food to Hills Prescription Diet Digestive Care I/D. She had one marble in 30 days but is now dropping them again on a almost daily basis. Her diet has not changed in the last 30 days. Has anyone seen this happen with there Frenchie?
