Please do not forget Weinberge lines
I joke. Weinberge have one fantastic psychism and power of inteligence , native defence, resistence , agility , courage, loiality and is ready to died for one loved thing but.....is a little problem. Have more personality. Is not verry good for obedience but like action.
About Moorieche lines i agree, because i sense Moreiche influence in my lines and is ok.
About Jivago -i know some puppy from Jivago lines , is good, is strong, strong psychism, have obedience in my opinion and have pleasure to work, good concentration. No have the best defend instinct but sufficiently and can be training- of course this depend by influence of other lines in combination .Is good.
