Megacolon can be very difficult to treat. I've had good results with Royal Canin's FIber Response diet so you could ask your vet about this prescription diet as an option for Bobi for long term management. It sounds like Bobi may be severely constipated now, and she may need to be hospitalized for IV fluids and multiple medications, or even manual deobstipation under anesthesia. There is also a surgery (subtotal colectomy) that can be performed that might help, so you could ask your vet about referral to a specialist.
