Home Canine Fertility Test Kits

breeding success

Having a canine fertility test you can use at home is invaluable.  Determining the fertile period for breeding dogs is the biggest challenge dog breeders face in consistently achieving all the big litters they want.  A home fertility kit for dogs based on vaginal cytology is a great solution.

The old rule of thumb – to breed on days 9 and 11 after heat starts – works fine for only about half the bitches out there, so what about the rest?  Fact is that around half of all bitches fail to show an obvious bloody discharge to mark the start of the heat (pro-estrus).  Many more are also far enough away from “average” in their cycle timings to make hitting the fertile period close to impossible without expensive testing.

The good news it you can easily, quickly and inexpensively deal with this situation at home using a combination of behavioral testing and vaginal smears (detailed in the DIY Canine Fertility Kit available below).

Use Vaginal Smears to Pinpoint the Fertile Period of Breeding Dogs

The cells lining the vagina change in appearance in response to rising and falling levels of the hormone estrogen, with a lag of 3 or so days.  So they are an effective rear-view “window” to see what stage the bitch is in in her estrus cycle and have been used routinely for decades as a canine fertility test.  The practice of taking smears of the vaginal cells, staining the smears and looking at them under the microscope is called Vaginal Cytology.

When she is in estrus, nearly all the cells of the vagina are distinctively different from normal, being large and flat with sharp angled edges and a tiny or absent central dark spot (the nucleus).  At all other times, such as in Pro-estrus and Di-estrus, most cells present are plump and round with a much larger dark central spot (nucleus).  So once estrus is over, diestrus begins and the appearance of the vaginal smear under the microscope changes abruptly back again to soft, round plump cells with large dark nuclei, very similar to those seen in an-estrus.

How Vaginal Cytology Helps Breeders

It only takes a few minutes to prepare a vaginal smear of your bitch.  As a canine fertility test, they are very useful for timing:

  • When to start natural matings and knowing when to take your bitch to the dog.
  • When to start artificial inseminations with freshly collected semen.
  • When to start progesterone testing for artificial inseminations with chilled or frozen semen.  Starting too early costs breeders a small fortune in time, vet bills and unnecessary hormone tests!

Fresh, good quality semen will last up to 6 days inside the bitch, while the eggs are only fertilisable for a small window of opportunity lasting around 3 days (approximately days 4, 5 and 6 after the onset of estrus).  This underscores the importance of achieving one or more matings early in estrus.  Late matings when the eggs are tired or dead will lead to very small litters or no litters at all!

Vaginal cytology will tell you when she is ready to take to the dog, thus ensuring you achieve the earlier matings that result in the biggest possible litters.   On its own it does not however tell you exactly when she ovulates nor when her most fertile period is likely to be.

Male Dog Fertility Check:

dog sperm count test microscope

Male dogs can lose their fertility quite suddenly.  The loss can be permanent as with an older stud dog that one day stops producing enough viable sperm in his semen.  Or male dog fertility can be temporarily lost due to poor nutrition, or an injury, infection or hot weather that warms the testicles excessively killing the sperm for up to six weeks after conditions improve.

The worst way to discover the loss of a male dog’s fertility is by missing out on litters or stud fees.  You may not even suspect there’s a problem until it happens multiple times in a row.  Imagine how much that costs you?

A better way is to take a single drop of his fresh semen and have a quick look at it.

With our Micra semen microscope you can rapidly check and do a:

  1. Dog Sperm Count Test – Is he producing enough sperm to be fertile?
  2. Sperm Motility (movement) Check – Is the sperm able to swim effectively and successfully make it to the eggs in the uterus?
  3. Sperm Morphology (appearance) Check – Does the sperm look nice and healthy or is it malformed? Abnormal sperm are not fertile sperm.

The availability of our Micra semen microscopes is strictly limited!  Get yours here.

And if you would like to learn how easy and quick it can be to collect your dog’s semen yourself, get our Dog AI Kit at the same time.  It includes the equipment you need plus an educational video.  The video shows you exactly how to collect semen from a dog in minutes plus how to safely inseminate it into a bitch.

DIY Canine Artificial Insemination at Home

What if her breeding reflexes and vaginal smears tell you that your bitch is fully ready to breed, but she won’t?  It is likely that your boy just doesn’t turn her on!  If trying her with another stud just isn’t practical, don’t despair.  An easy way around it is to do your own Artificial Insemination at home.  Cheap, easy, quick and highly effective, DIY AI is a great skill to master.

You can get our full Canine AI Kit including instructional DVD, user’s manual and the re-usable equipment you need here.
