Progesterone Testing

Same day in-house blood test

Progesterone timing and testing is the single most helpful tool in a successful breeding and whelping.  Timing is EVERYTHING when it comes to breeding and whelping dates.

We strongly encourage progesterone testing starting at 5-6 days from the first sign of your bitch being in season.   Ideally, we like to see a pre-ovulation number, a number near ovulation, and a number confirming that your bitch followed through with ovulation and showed evidence that she continued to rise in progesterone.

So much weight is often put on numbers; but it is important to understand that once your female has ovulated the numbers mean MUCH less.  Timing from ovulation is KEY in planning breedings and the best breeding methods.  We cannot express the importance of proper progesterone testing for your breeding success! 

We have two different machines running at Subzero.  They are carefully calibrated regularly and are always up to date on routine maintenance done by laboratory technicians for those specific machines.

LH (Luteinizing Hormone) Testing

LH testing is under-utilized blood test that allows us the ability to further pinpoint the exact time of ovulation- THE MOST IMPORTANT DETAIL in breeding and often in planning for whelp.

Artificial Insemination - Subzero Reproduction Canine Reproduction Services

Artificial Insemination

This includes and semen evaluation as well as proper AI technique.

This is a fairly simple procedure, but we have sadly seen these go terribly wrong when attempted by inexperienced (and experienced) individuals who have caused injury to a female or the end of her potential to breed. Please have your AI’s done by a licensed veterinary professional.

Transcervical Insemination

TCI’s done well and correctly can be an invaluable breeding resource.  It is much less invasive than a surgical implant where you must worry about all the dangers that go with anesthesia and full abdominal surgery.   We have over two decades of experience performing transcervical inseminations.  We use the best scope in the business made by Karl Storz for optimal performance and success.

We invite your questions and will always allow you to be present so long as it is in the best interest of your pet.

A TCI is only as good as the technician or doctor performing it.  The discrepancy of the skill level in individuals performing TCI’s is EXTREME.  We consider ourselves some of the very best at this procedure and we have been involved in the training and education for local veterinarians and technicians.

We are proud to offer state of the art Idexx radiology technology and equipment, which allows the clearest of images to be provided to our clientele. This is especially helpful when needing to determine final puppy count prior to whelp. 

We are also proud to offer OFA (Orthopedic Foundation for Animals) image submissions.  This is a requirement amongst many AKC breed clubs and may include several different image types such as:

      • Hips
      • Elbows
      • Trachea
      • Shoulder

Please call ahead to verify availability.  In most cases, we are able to accommodate same day scheduling, but want to make sure we are able to dedicate all the time necessary to obtain excellent images.

Ultrasound Scan - Subzero Reproduction Canine Reproduction Services

Ultrasound imaging can be a great tool when confirming pregnancy 28-35 days post breeding.  This is a painless and very comfortable diagnostic to have done and it allows you to be apart of the experience, too!  We are able to take photos and video of the ultrasound and send directly to you in a matter of minutes.  

Celebrating successful breedings is one of our most favorite things to do with you; so helping you share that moment with prospective new homes awaiting the arrival of your litter makes it all that more eventful and special.
