Cooled Semen Shipping

Cooled semen shipments have been used for 25 years in the horse breeding industry and now dog breeders can benefit from this convenient form of long-distance breeding.

After the semen is collected from the stud, an extender is added to the sperm rich fraction of the semen to maintain longevity and motility of the sperm. A semen analysis is also performed to make sure the stud's semen is of sufficient quality to produce puppies. The sample is then packaged and shipped to you by Fedex. If you are interested in learning more about semen collection and cooled semen transport, please visit our Resources page.

What We Need from You

Inseminating with shipped semen is not much different from inseminating with fresh semen, but there is a bit more planning involved to make sure the shipment arrives on the best day to inseminate.

  1. A copy of your female's pedigree and photo for our records and for filling out the breeder's information for registration (taken from the final price) to guarantee you a spot, when your female is ready.
  2. Which stud you intend to use
  3. The first day of your female's heat (if using a vet he can tell you what day the semen will need to be inseminated).
  4. When you will need the semen. We need to know the day prior so it can be shipped overnight for next day morning delivery. We will need to know before 4:30 pm if you need semen for the next morning. NOTE: Before semen is shipped all fees must be paid in full to ensure no delay on shipment.

  5. Contact name, shipping address, and phone of to whom the semen will be shipped.

When You Receive the Sample

Checking the Motility of the Sample

  • Motility of the semen sample always should be checked prior to insemination.
  • Motility analysis should always be performed on samples warmed to 37°C (chilled sperm can appear non-motile or sluggish until warmed).
  • Gently invert the sample tube several times to mix.
  • Using a pipette, place a drop of semen on a pre-warmed microscope slide and cover with a pre-warmed coverslip.
  • If available, keep the slide on a slide warmer or a heated microscope stage for a few minutes before checking the motility under the microscope.
  • If your veterinarian does not approve of the semen quality, do not inseminate the female (see breeding contract for more information).

Preparing for Insemination

  • You may chose to inseminate the entire dose, or save half for insemination on the next day. Enough semen will be shipped for either case.
  • Gently invert the sample tube several times to mix.
  • If you chose to inseminate on two consecutive days, draw up half of the semen dose into the insemination syringe and store the remaining sample in the refrigerator overnight. (Divide the sample into two doses before warming. Do not warm the sample then re-cool it.)
  • Warm the semen sample to be inseminated in your hand or pocket for a few minutes.
  • Inseminate the female immediately.
