What do you mean by firm? What do you use for corrections? If you use corrections, where is her threshold? Do you kiss your dog around the face area? Do you make her wait for a command before eating? Do you feed yourself before her? These questions need to be answered before you can get qualified responses.

I read through the NILF article and I think it is great advice. I take the feeding situation a bit further, at least when raising a puppy, that they not only to sit but have to wait for a command to eat. One thing I might add is that the NILF article mentions "for normal dogs" sometimes certain Dobies may not quite fit that description. I may not be PC but am not opposed to what some may describe as a "harsh" correction if the situation calls for it.
