Dog dream need help interpreting?

I have had a dream similar to this one in the past. In my dream i am getting a building ready to start my own buisness, the buisness is an art store and we specialized in drawing senior pics for our clients. Im carrying up a blank canvas while my employees are debating on what kind of pics to do. We have a german shepard we keep at the building. While im inviting a friend and my mom to dinner, i have a vodoo priestess bless the building. The priestess gives us some ribs to eat and i feel strange eating them, then the priestess puts the head of the german shepard on the table, she also informes us that we are eating its ribs. I get sick and realize the dog is still alive, its head reatached but with no ribcage. It comes up to me and tries to cuddle up to me but it cant seem to keep its head from wobbling. I dont understand why i had this dream please someone help me!!!!
