The invention belongs to the field of an animal fur processing method, and particularly relates to a bicolored dyeing method for rabbit fur. The bicolored dyeing method for the rabbit fur comprises the steps as follows: (1), the rabbit fur which is not dyed is preprocessed; (2), dyeing: the preprocessed rabbit fur is dyed by solid fluorescent dye as fur tip dye, and then one bath dyeing is performed and top snow dye is added for dyeing; and (3), a discoloration liquid prepared by a chemical discoloration agent is adopted for performing fur tip discoloration processing on the dyed rabbit fur, wherein the solid fluorescent dye is anthraquinone type sulfonic acid sodium salt, the main component of the solid fluorescent dye is sulfonic acid sodium salt, and the content of sulfonic acid sodium salt accounts for 10%-30% of the total quantity of the solid fluorescent dye. According to the bicolored dyeing method for rabbit fur, the discoloration is thorough, the bicolored effect is better, the color is natural after discoloration, the color is not changed after the fur is scalded, and the discolored tip part can be made into double colors after the color is discharged.
