I have had Dolly since 8 weeks. Yes I have tried very hard to potty train her, I potty train boxers ALL the time. In her defense she was my first small dog ever and they are different. AND she did come from a 'large breeder' who didn't work with them as puppies and she was kept in a cage where the waste fell away from the puppies-- until I got her.
I am very sorry to hear that about LPN's dog I will have to give her a shout saying I'm sorry to hear that. Darn, that's so sad when that happens.
