So you may be wondering why do we progesterone test dogs at such precise accuracy. Our modern cutting edge, state-of-art ovulation testing machine can ensure a more successful mating. We use veterinary grade equipment for guaranteed accuracy optimising the chance of pregnancy even further. Thus saving time, stress, money and loss of a rewarding experience.
We run progesterone testing for a number or reasons. The most popular reason for testing is to analyse a bitches most optimal breeding window. Not only do we also offer reverse progesterone testing to find out the most likely time they will whelp. The same hormone ‘progesterone’ is also vital for science in human pregnancy.
Reverse progesterone testing is a valuable tool for you and your veterinary surgeon as the hormone progesterone falls to a certain level around the time puppies are ready to be born. So for example, when planning a Cesarean, timing is crucial and if there is any doubt about getting the days right, you can reverse progesterone test to find out whether labour and whelping is imminent or not.
Just as progesterone testing analyses the occurrence of ovulation and subsequently when to mate or inseminate it is also very useful to monitor for the other following reasons. The level of progesterone needs to stay elevated to sustain a pregnancy, not only does it fall to the end of a pregnancy it also triggers whelping.
By monitoring the progesterone hormone during pregnancy a warning of a premature fall in progesterone indicates the time for you to request your veterinary surgeon to intervene immediately to keep the progesterone level elevated with medication.
The worst nightmare for breeders is often “Single Puppy Syndrome”. This is when the bitch is only carrying a single fetus. Small litters in general sometimes may not stimulate the uterus enough to whelp successfully. This can result in a “Primary Inertia” a condition where a bitch fails to go into productive labour and expel any puppies due to partial absence of contractions and an unobstructed birth canal. Small litters often have this effect and lead to obstruction due to their freedom for colossal growth.
Complications often occur during pregnancy and whelping, so it’s crucial to know the delivery date to ensure the health and well being of your bitch and her pups.
Not everyone has their own stud dog what will indicate the best time to breed. And even when you do, they may mistakenly get it wrong and want to mate anytime. Most breeders will eventually need to bring in new lines to the breeding program. So when paying stud fees, travel arrangements to the stud dog or the purchase of chilled semen and transport, artificial insemination, it all tots up. We need the scientific assurance when breeding! Ultimately in conclusion, pre-mate progesterone blood testing for dogs is the way forward for your success producing puppies!
The overall investment including also the cost of a quality bitch will be a lot of money. So you need certain assurance that your bitch will be 100% ready to breed at a specific time. Canine progesterone blood testing takes away all the most important uncertainty out of dog breeding. Our ovulation testing provides the best analysis for when to mate or inseminate.
Lastly, it’s very important to understand that there are many methods of ovulation testing before breeding. Options available to breeders are endless with numerous products now on the market for pre-mate testing. Another method is, Canine Cytology which looks at the changes in the cells from a vaginal smear. There is not one other method which is more accurate at predicting the best time to breed other than progesterone blood testing.

When bitches go beyond their expected delivery date unknowingly, breeders often get told to go home and wait for nature to take its course by their local vet practice staff, inexperienced in canine reproduction. That is when they are not after your money of course. But this can sometimes lead to a disaster in the loss of the puppy when dealing with “Single Puppy Syndrome” or all the puppies in the litter for this matter.
If the progesterone level has already fallen and the bitch has failed to whelp, if in doubt Reverse Progesterone Testing can be the most beneficial in knowing when to intervene. Reverse Progesterone Testing can be important if previous failure to carry a litter full term suggests there was an early fall in progesterone.
