A four-month-old, entire male, German wirehaired pointer presented with tenesmus due to type I atresia ani and with urination observed through this stenosed anal opening. A positive contrast retrograde urethrogram demonstrated a urethrorectal fistula and stricture of the penile urethra. Urine culture revealed heavy mixed bacterial growth, which was treated with appropriate antibiotics. Surgical correction of the congenital urethrorectal fistula was performed via a perineal approach with a 3.5 French catheter placed retrograde into the fistula to facilitate its dissection. The anal stenosis was addressed by surgical anoplasty and the urethral stricture via a scrotal urethrostomy. The dog recovered well with the owner reporting complete resolution of the clinical signs and urination via the urethrostomy site at six months postoperatively. To the authors’ knowledge, this is the first reported case of congenital urethrorectal fistula associated with type 1 atresia ani in a male dog.
