The relationship between 9 year old Minnie and not quite 4 mos Fergie is an ever evolving one. They play more and more every day but Minnie always seems especially cranky in the morning with the pup. Last evening they played hard and the "not getting along" portion of the morning lasted longer then usual. Does sore have any impact on cranky? Just wondering your thoughts on this. Minnie is in great shape other then age.
