Lisa, welcome to the site, condolences to you in the loss of your son and roxie.
I think the dynamics of the relationship will take time. Take them out on brisk walks together, but I would limit the free outdoor play time til they work out the relationship. Maybe give each one on one alone time w/ you to get her to bond w/you. Three days is not long at all and both of them are going thru adjustments.
I dog-sat a gsd yesterday, and my dogs and her(all girls) had a hard time playing as they all wanted to act like the big dog, even though they all really just wanted to play. But because they didn't have a relationship yet, defenses were up. We had no problems as long as I was there to correct the drama/overacting...
