Most dogs ejaculate in three fractions – the first fraction is initially clear to slightly cloudy and before the release of the sperm, the second fraction should be milky white and thick as this is the sperm-rich fraction, the third fraction is the prostatic fraction and should be clear in a healthy dog.
(i) Normal Semen Quality - Semen from a male dog is normally a cloudy white fluid, ranging in volume from 1 ml to 30 ml, containing 300 to 2,000 million sperm per ejaculate, of which more than 70% are motile and morphologically normal (i.e. structurally sound).
The process involves manually stimulating the dog to ejaculate and collecting the semen in a sterile container. The sample is then evaluated under a microscope to assess sperm motility and morphology. Sperm motility refers to the movement of the sperm and is an important factor in successful fertilization.
Healthy semen is a cloudy white color with a jelly consistency similar to a raw egg. Slight changes in semen color, texture, and even smell might be normal and should no pose concern. In some cases, semen color changes could be a sign of an underlying issue.
Fresh ejaculated canine semen has the longest viability. Semen from young, fertile stud dogs can survive for up to 5-7 days in the bitch's reproductive tract.
How Long After AI Does a Dog Get Pregnant? Dog conception should occur 24 to 48 hours post breeding. Depending on the type of semen (fresh versus frozen semen) used. After conception, the egg repeatedly doubles the number of cells to create an embryo.
A whopping 40% of female dogs will fall pregnant after just one mating session! That incredibly high number means you are at considerable risk of having a litter of unwanted puppies if you are not careful. Thankfully, there are relatively safe means to prevent pregnancy after mating.
You should see your healthcare provider any time you notice unusual body changes like yellow or brownish semen with specks. Brown or speckled semen may indicate blood in semen (hematospermia). Yellow or brown semen may not be cause for concern. But it could indicate a problem that requires treatment.
Unhealthy sperm can look very different from healthy sperm in terms of color, shape, and size. Normal healthy sperm ranges in color from a transparent to a grayish white, while unhealthy sperm can often appear yellow-green or off-white.

Color of the sperm rich fraction can vary from yellow (usually contains urine or bacteria which can kill sperm), to red (usually contains red blood cells which do not kill sperm), clear (usually very low sperm count or the stud dog has withheld the release of the sperm), turbid/thin (usually a lower amount of sperm ...
Dog sperm looks similar to human sperm, but unlike the human version, dog sperm isn't ready to fertilize an egg right away. That's because dog sperm has a coating of cholesterol that covers its head, where the DNA information is kept.
In this study, the kernechtrot–picroindigocarmine (KPIC, aka Christmas tree stain) staining properties of semen from 8 domestic dogs was compared to two samples of human sperm. In the head of the dog sperm, the acrosomal region stained pale red and the postacrosomal region stained dark red.
Green discoloration is indicative of prostate infection. Volume varies depending on how much of the third, or prostatic fraction of the ejaculate was collected. Volume is not correlated with quality. Motility should be assessed soon after semen collection.
Semen collection and evaluation is the best correlation available to determine if a dog has the potential to be fertile. A semen collection should be performed prior to breeding. Through this collection, the motility (movement) and morphology (appearance) of the semen can be evaluated.
As men get older it is also usual for their semen to become slightly thinner with less volume being produced at ejaculation. It is therefore quite normal if there appear to be clumps of jelly-like globules in your semen and there is nothing to worry about here.
This could be caused by inflammation of the prostate or the glands that help produce semen. While red semen can be alarming, the cause is usually harmless (benign), especially in younger men. Yellow or green semen. This could be caused by an infection, jaundice, or the presence of vitamins or medication in the semen.
Some studies suggest that moderate ejaculation (2–4 times per week) is associated with a lower prostate cancer risk. However, ejaculating more often doesn't mean your cancer risk drops even more.
Dogs new to mating may experience a bit of anxiety at being locked together, but it's a natural process. Help your dog to remain calm and stand still until the two can safely separate. This will occur on its own once the male dog's arousal subsides.
If a female dog has mated with two or more male dogs, she can have puppies from different dads in the same litter. While the puppies may have different dads, each individual puppy will only have one father.
How often do female dogs come into estrus? On average, estrus occurs about twice a year, although it varies from dog to dog. Small breeds tend to cycle more regularly than larger breeds. The interval between heat cycles tends to be four to twelve months with an average of seven months.
