This case report describes azoospermia in a French bulldog. The dog, with historical evidence of unsuccessful insemination after both artificial insemination and natural breeding, presented with physiological parameters (testosterone levels and karyotype) within normal ranges. Scrotal palpation and ultrasound of both testicles indicated aplasia of the epididymis and vas deferens. Two seminal samples were examined and no sperm cells were found. In conclusion, before starting an assisted reproduction procedure, it is necessary to perform sperm analysis to determine the reproductive capacity of the dog intended as a stud dog.; Ovaj prikaz slučaja opisuje azoospermiju francuskog buldoga. Pas, s prethodnim anamnestičkim nalazima neuspješne oplodnje, kako nakon umjetnog osjemenjivanja, tako i parenja, imao je fiziološke parametre (razine testosterona i kariotip) unutar normalnih granica. Palpacija skrotuma i ultrazvuk oba testisa ukazali su na aplaziju nuzjaja i sjemenovoda. Ispitana su dva uzorka sjemena i nisu pronađeni spermiji. Zaključno, da bi se odredio reproduktivni kapacitet psa namijenjenog za rasplod, potrebno je prije početka postupka potpomognute oplodnje obaviti analizu sperme.
