    Summary · context
    Semen was collected from each of the 3 dogs once every 3 to 4 d for a total of 6 collections per dog.
    Summary · context
    Ten minutes before each collection, 1 of 3 injections (oxytocin 10 IU [0.5 mL], IM; PGF2alpha 2.5 mg [0.5 mL], IM; or saline 0.5 mL, IM) was administered.
