Vis the Xanax/alprazolam, have sometimes found that benzodiazapines taken to manage situations I find threatening (irrationally or otherwise), make my head fight the drug as it gravely fears any diminution in excessive vigilance.
Similar may be true of your collie? Probably a stronger dose will sedate her enough, but could make her more frantic than ever.
Accordingly, consider giving her the alprazolam once the perceived threat has passed. This could let her unwind faster & also to come to associate perceived threats as something to notice, but which she can relax about once they’ve passed on.
