Relocating, can’t afford groceries or dog food

I’m relocating to a new city 7 hours away from home for a job and they are NOT paying me to relocate. I guess I’m not fully prepared. I have enough money for the gas to get me there and for my first months rent which fees make really expensive), but only rent. I’m going to be living with my bull terrier, so I am not alone and so that I am protected. I willl later bring my 16 year old chihuahua. I don’t have enough money for dog food, food for myself, nor for oil which my car desperately needs to make the trip . I won’t be getting paid until 2 weeks after my start date so these two weeks will be hard. My goal is $300, but a little extra helps just incase my approval for housing at my job does not come though on time. Even though I have asked my employer several times, I am afraid they will ignore the request until midday of my moving day. I may need to stay at a motel.  Anything helps. Hell I will be happy just making $50 on here! I will find alternative ways to make money. Thank you for your time everybody.
