to the board Melanie and Sadie. I love the photo of her she is a real cutie.
The potty training can be a hard time when they are young. I was lucky with Chloe I would give the do pee pee command when outside and she would go straight away. With plenty of praise and treats they soon get the message. As you mentioned Sadie already knows basic commands so hopefully she will soon follow out a toilet command.
