the truth is frosty and jack are both right. we can all sit here and name kennels that have done both and been successfull. but i will say this i beleive those large kennels that simply feed clean and condition are successfull despite the no bonding due to the fact that they have an abundance of individuals to choose from whe u got 30 plus dogs and u are a good conditioner handler and breeder u are going to get some good ones no matter what but i am a firm beleiver in small yards having better quality and percentages 6 dogs max and friends with similar blood that also keep thaat much and u exchange dogs and breedings can be the best chpoice
