This is the first German case report of an alpaca cria suffering from a congenital vulvahypoplasia. Symptoms, diagnostics and therapy are described. The 24-hours-old cria was referred to the hospital due to reduced general condition and colic. The existent vulvahypoplasia led to impaired urination, causing further complications such as urovagina and urinary stasis up to the renal pelvis. Surgical construction of the rima vulvae cured the cria. As indicated by several cases published on the clinical picture of vulvahypoplasia during recent years, this congenital deformation could become an increasing problem in the alpaca population.
