need money for Torn knee ligament/cartilage surgery

My dog is suffering from a fatal disease called Cranial Cruciate Ligament and Anterior Cruciate Ligament Disease.

Medical practice is described The stifle joint is the joint between the thigh bone (the femur) and the two lower leg bones (tibia and fibula). It is the quadruped equivalent of the knee in bipeds.A ligament is a band of connective or fibrous tissue that connects two bones, or cartilage, at a joint; the cranial cruciate ligament is the ligament that connects the thigh bone with the lower leg bone - it helps to stabilize the stifle joint. Cranial cruciate ligament disease , also referred to as the anterior cruciate ligament (ACL), is the sudden (acute) or progressive failure of the cranial cruciate ligament, which results in partial to complete instability of the stifle joint. Cranial cruciate rupture is the tearing of the cranial cruciate ligament; it is the most common cause of rear-leg lameness in dogs and a major cause of degenerative joint disease (progressive and permanent deterioration of joint cartilage) in the stifle joint; rupture may be partial or complete.The possibility of a genetic link is unknown. An understanding of the role genetics might play may be important in increasing the likelihood of actively restraining stifle deficiencies and/or structural (conformation) abnormalities. What is currently known is that all breeds are susceptible. Specifically, the incidence of cranial cruciate ligament disease increases for rottweilers and Labrador retrievers younger than four years of age, dogs older than five years of age, and in large-breed dogs from one to two years of age. The predominant gender this affects is the spayed female.

It takes about $ 1500 to treat this disease, which I do not have. Because my country is very poor, so many people still live under the poverty line .In that place, dogs are treated like a Living beyond one's means.

I love my dog a lot but I'm helpless because I do not have enough money.I can not look at my dog Because she's always suffering and I can not do anything for her. I want my dog to stay well for a long time.please help me .
