Hehe, the fact that he is picking everything up is very puppy! June also does this, which is why I can't live without the 'leave it' command. She is quite obedient and eager to please, so she obeys immediately. But she still picks everything up - I must sound like a irate mom when I am with her, 'cause it is always like 'leave it', 'leave it', 'leave it'. But she is too cute.
With regards to the toys, I suggest that you pick up all the toys at first. Then slowly introduce them to the least fun ones first, building up to the great toys. However, if they aren't fighting over the toys, it is fine.
Cash also took all of his toys away and put them out of reach for June, he also stole all of her nice, new toys and hid them.
I didn't do anything except pick up a certain toy and playing with them both with it. Cash quickly caught on that tug-of-war is much more fun with June and he now loves to play with her.
Every morning, they race through the house, playing with the toys, growling and wrestling. Phew, mornings are crazy with these two.
If they aren't fighting over the toys and she is simply taking them away, there isn't a problem. Just get her to play with him, with the toys. I often initiate play since I know both dog's play triggers, but after the beginning, they don't have time for me. I am much too boring for the rocket babies
