Let me tell you few things. Why you are going with a group? Because K 9 used that doesn't mean that’s good .They don’t want to waste their time with slowly dog’s learning .They want fast and efficient ,no forgetting only in favor of time and money like everything here. No questions about thinking and making decisions, they need robots who will do things on command: Grab- leave !!!That’s it.” No questions asked, team playing.” Dogs didn’t picked us to live with us .We picked them 14.000 years ago and we designed them through History the way we liked .We took a role to create them. But we are not God, we shouldn’t judge but that we are doing it and before and today. We manipulate them on any possible way!!! Unfortunately God create us with possibility to speak and not them .So when introduce your family they don’t have any other choices they can’t meet friends, making friendships, they can not talk like us, they don’t go for a walk without us, we are making decisions for them ,what they going to eat (Dry grinded brick called Dry food ,or table scraps and ect),how many times a day , We train them ,we beat them ,we deciding are they going to have a sex or not we change God creation to neuter them and so many other things bed or good things on our judgment. And who we are ?Busy people with develop individuality in struggle to survive ,loans ,mortgages, stubbing each other in a back. But on the end they are still wolfs same as 14000 years ago same number of chromosomes 78.They still have a same mind that can feel elation ,anger , sadness ,thirst or hunger or exhilaration. Dogs are sentient beings very much aware of their own personalities .They have minds as much as we have .Their brain can store information on two ways .First it stores information concerning the relationship of one event to another ( Like Pavlov’s thing with a bell )and second is called “Instrumental conditioning”( when you teach him to retrieve or something similar) So our creation against God creation ? Conflict of what , you tell me ?That’s why they have on our opinion unpredictable reaction .We don’t now why? Then if we don’t now , have a seat and study or pay somebody to teach you or start to think about what we are doing to make them doing it or what somebody in their blood lines did it before to make them do this things. No force no more human smart ass, get back to start thinking about them like real friends and more of it. I bet you if your life come to danger non of your friends will NOT risk their life to save you except your dogs!!!! I now believe me. Happy studying
