my maltese does the same thing

one time she scared me I was on the computer home alone cause i didn't want to go to the store that day

and she busts out running down the hall way barking it was a bark I had never heard her do before

so I grab anything and go to look in every room and nothing was there so i was like it's ok snow everything fine then she stops lays down then gets up and does it again only this time she does come back to get me

i'm like where did she go all of sudden i hear this big bang

i'm like almost in tears thinking shes hurt or something

shes siting there in the bathroom looking around a little scared but the strange thing about it is i closed that door

i was so freaked out I kept making up excusing in my head thinking I may have left it open a little by acciddent
