My memory of this film may be very wrong, but i rember it was english and in color i dont know what year looks early 2000,s from my memory i remeber a group of kids or young adults driving in the desert and a dog like creature maybe something like a chupacabra and i rember the people hiding in a shack made of thin sheet metal and wood beams and a blue pick up truck out side at night and at the end only one girl with black or dark brown hair survives and her eyes are bloodshot from what i assuime to be an illness.
Sound like the absolutely brilliant Feast (2005)

yes ive watched that its not what im looking for i found one that fits closer called Chupacabra Territory but its through perspective of a camra almost like a lost footage style but even that film isnt right either as they are in a camp ground not a shack made of flimsy sheet metal and i know its not reeker that im looking for
Unearthed (2007)?
