Dog sperm, or more accurately, dog ejaculate, isn't uniform in appearance throughout the entire process. It's released in three distinct fractions:
- First Fraction: This initial portion is typically clear to slightly cloudy. It's released before the sperm.
- Second Fraction: This is the sperm-rich fraction. It should appear milky white and thick. This is the most important fraction for fertilization.
- Third Fraction: The final fraction originates from the prostate gland. It should be clear in a healthy dog.
Therefore, when assessing dog sperm, you're looking for a distinct milky white and thick fraction as the primary indicator of sperm presence and quality. The clarity of the first and third fractions are also indicators of the dog's overall reproductive health.
