Plain-English summary
A 10-year-old female mongrel was brought to the vet after her owner noticed bleeding from her vulva. Tests, including an MRI and endoscopy, revealed a grape-like mass near the urethra, which was diagnosed as a type of cancer called botryoid rhabdomyosarcoma. This is the first known case of this specific tumor developing in a dog's vagina. Unfortunately, the details about treatment and outcome were not provided, so it's unclear how the dog responded to any interventions.

Abstract
A 10-year-old, female, mongrel showed hemorrhage from vulva. By magnetic resonance image (MRI) and endoscopic examination, a multipapillary mass with a grape-like appearance was found around the urethral opening. Histologically, the mass consisted of variable-sized round-, spindle-to-polygonal-shaped tumor cells including many multinuclear cells. Mitotic figures were also frequently observed. In some areas, that tumor cells were loosely arranged, with intercellular myxoid components. Immunohistochemically, these tumor cells were strongly positive for vimentin and focally positive for desmin but negative for myoglobin. Thus, the case was diagnosed as a relatively poorly differentiated botryoid rhabdomyosarcoma by the macroscopic, histopathologic, and immunohistochemical identification. This is the first report of botryoid rhabdomyosarcoma developing in the vagina of a dog.
