Presuming you have been breeding dogs for some time now (?) is that where your thoughts come from..?
It is an interesting topic indeed, when I get some time I will translate what's being said so more could join the talks.
I personally have not bred dogs myself, but have been directly and/or indirectly involved and mixed with breeders, trainers for the last 20++ years..
These 'old school breeders' have 100++ years of combined knowledge and experience with the bloodlines we have chosen..
I believe that most dogs have missed out on a true family pack, where the Sire can contribute many positves.
For example the pup can figure out who really is the 'ALPHA BOSS' and what 'to do' and 'not to do'.. This has helped me i feel, as Casso knows his position in his new family, and probally thinks i'm a bit like his Sire Mad Maxx

..
Casso was taken out from his family pack at the age of 13-14 weeks, so he would of had many differant experiences 24/7 days a week with Mad Maxx being around...!
Where there is a positive there must be a negative i feel, and an example if i can suggest would be that the young pup is bitten and scarred by a Crazy dominant Male..
Am sure we can think of many positives and negatives in regards to being part of a complete family environment..
