Assalamualaikum, Ahsan Allahu ilayk dear Ustadh, a package of dog food arrived at work and I just gave my signature and brought it to my boss. Considered I live in a non muslim country and that food isn't halal, is there anything on me for this case or does the blame fall just upon him for buying it

Ustadh AbdulAziz al-Haqqan

Receiving the package itself is not forbidden, especially that you do not even know if the dog food in it is actually forbidden or not.
