Meagan Leavey (2017)

This is a good movie that incorporates two things that are really true for war veterans returning home now.  They have a lot of trauma, and as women, they have had a lonely war.  So when Megan joins the military because she basically has no other viable options, and discovers that the Army is not her friend, she is a bit at sea until she gets a whiff of the canine units.  She inherits a dog, Rex, who is highly skilled at sniffing bombs and also a high maintenance dog who is hard for handlers.  Megan, who is not welcome with open arms into this unit either--women face a lot of battles before they even get to the battlefield--but the fact that Rex trusts her and he doesn't trust anyone wins her a lot of points, and they are basically inseparable. They are both wounded in an event that ends their war, but saves lives, and then Megan goes about finding a soft landing for Rex, against all odds.
