I take exception to the OP's if you want to know something pm a breeder. There are a ton of people who are members of this forum that know a ton of stuff. Most are NOT breeders. To be perfectly honest there are few breeders on here who I would take advice from. Not trying to be rude or disrespectful but it is the truth.
If I want to know about food I ask members like LOR, Mafia, Wandering ect. Training I would head straight for Gunny. Behaviorial stuff could come from any number of reliable sources most of which are pet owners not breeders. (Yes I am aware Wandering is a breeder)
What I am trying to say is that there are many answers to the same question. One thing may work with your dog but not mine. That's why it doesn't bother me to hear the same question over and over again. There is always something to be learned.
