I must say that I did keep my little Mango on a strict schedule regarding feeding and potty breaks, although not quite as rigid as the one above. Now, after having her home for just 6 weeks, I would say she is 90% toilet trained
She will only have an accident (maybe) if she is upstairs and has no access to her doggy door. By the way, the flap of the door I had to tape up because she is too little to lift it herself - she is now 2.2 lbs at 4 months, so hopefully she will soon be "heavy" enough to open it herself.
