correction/reduction of treats/playing with other dogs
I am wondering for a 11 week old gsd should corrections be given? My pup has been able to sit/down now for a week fine with and without food treats 99% of the time. But this changed 2 days ago, where he would not do it for me, but would for my partner. I feed and have done training with him whereas she has not (but he always has also followed her commands), and then today, he also has stopped listening to her. When food treats were brought out he did them everytime. After we are sure he has learnt sit and down (which im sure he has) should be cut out the treats until we start learning recall? His 'attitude' has also changed which may be related to the question below -
I watchedin a leerburg video something about not letting 2 dogs freely play together, but no one else has ever told me this? my pup has been with a friends dog for small periods of time (less then 1 hour) and we have always been close by, but since christmas eve/day/boxing day he has spent much more time with the other dog, continuosly playing (sometimes roughly) and sometimes not in right in front of us supervised. Is this bad, and could it be contributing to the problem above. I have also noticed the last couple of days he hasnt been his usuall excited self and want to play as much?
