OK let me re-emphasize this for all of you that just called me.
Just because a breeder has had multiple litters over a few years does not make them an expert.
If they have not improved their lines they are not doing something right so they are NOT an expert in the breed. Have they, themselves gotten any champions in their lines? Have they themselves gotten any working titles, obedience titles or temperament titles on their own dogs? If the answer is NO then they are far from someone who should be giving anyone advise. It takes years of training experience and working experience to become an expert at anything. So listen to those who train, work and show their dogs not to the computer warriors and self proclaimed experts.
