I think it is going to depend on the meeting with Moose. If they have a connection - and are going to be great friends, it will not be too stressful to move after about 4 months. If it doesn't go well and the relationship is going to need some work to get them acclimated, then it might be too stressful on both of them.

I think you are going to have to go with your instincts. I always think that a dog chooses us and you will know if it is right for the entire family.

Good Luck
