Abstract: Congenital abnormalities are structural or functional defects present at birth. In the canine species, although few studies are available, it is estimated that congenital disorders occur in 1% to 2% of individuals. These anomalies may be lethal, sublethal, or compatible with life, potentially causing only cosmetic alterations or, in some cases, no clinically relevant effects. The present report aimed to describe multiple congenital anomalies identified in a neonatal dog. A one-month-old male Poodle puppy was presented for clinical evaluation with a history of hyporexia, body size smaller than expected for age, and abdominal distension. Physical examination revealed several congenital defects, including anal atresia, agenesis of the coccygeal vertebrae, and scrotal hypospadias, the latter characterized by the presence of an ostium located in the caudal third of the penile body. Around the abnormal urethral opening, urine and softened fecal material were observed, a finding suggestive of a urethrorectal fistula. Additional abnormalities included incomplete fusion of the preputial raphe, resulting in complete exposure of the inner preputial lamina and the penis, which was aplastic. Surgical correction was attempted; however, the puppy died during the procedure, and necropsy could not be performed. A thorough physical examination of canine neonates should always include the assessment of potential congenital anomalies, as many of these defects may impair development and compromise animal welfare
