LH Surge Test Strips



LH Surge Test Strips identify the surge which triggers ovulation giving the breeder a better understanding of the timing of the ovulation in your bitches. You do not breed the day of the surge when the strips change color.  It takes two days for the eggs to start to be released and another two days for them to ripen and become sperm friendly.  We suggest trying your first breeding 3-4 days after the strips have identified the Surge.  

PayPal is accepted in US currency. A PayPal account is NOT required to order.  Credit/debit cards are accepted at checkout.

Delivery is via USPS Priority or Express service. International shipping is also available below.

Instructions are included with each order.

LH Surge Test Strips are shipped in a Mylar pouch with a silica gel pack for moisture absorption to preserve freshness and for storage.


NOTE: Each female will vary from cycle to ccyle. The LH surge can vary and occur at any time during a cycle, early = day 3 or later = day 21 or more. If you get 10 test strips and run out before day 29 due to a late LH surge, you will NOT see a color change, which is not the fault of the test strips. The test strips do NOT guarantee ovulation, fertility or conception. Use of the test strips is at the buyer's discretion and the seller assumes no liability with the use of the product.

 Record Keeping

Maintaining a record of the test results is very important. Take a picture of each test result to save the results. Place a piece of clear tape over the strip to prevent air exposure. Save them on a chart indicating the dates, times and any notes. Keep the strips and records in a cool dark dry place. Chart Download In the days before we had progesterone blood draw testing, the rule of thumb suggested that we breed on day 12-14 of the heat cycle, with day one being the first sign of red blood. Poor timing resulted in more missed breeding than we care to think of. Today we know there is a lot of variance in ovulation timing which is why the LH Surge is now the factor that breeders should be spending more time learning about.

The test strips identify the day of the LH surge, by changing color to indicate the SURGE is occurring giving you the ability to time the breeding. You begin testing twice a day until you see a color change from pink to shades of blue/burgundy or black.  Simply lay your bitch on her side and gently open the lips of the Vulva and place (do not insert) the Strip in between the lips and close for 30 seconds, take it out and read the results. The strip will come out a shade of wet pink if the SURGE is not occurring or it will change color. Take your bitch out for a pee before starting to reduce the chance of a small clot of blood obscuring the results.  It is really that SIMPLE.

The change in color does NOT mean you breed the day of the color change.

Remember, the SURGE identifies the LH hormone that triggers the release of the eggs which are not ripe and ready to accept sperm. It takes two days after the LH surge for the eggs to be released and another two days for them to ripen, so you can introduce your mating pair 3-4 days after the color change and ovulation should be in full swing and then breed your normal pattern; i.e.: breed two days in a row and then skip a day and breed again (this will catch any late releasing eggs).

Natural ties can be achieved this way without the use of a blood draw, but if you are going to do frozen or chilled semen breeding, most Vets and reproduction specialists will want an exact ng number and that can get expensive.  By using the LH Surge Test Strips to identify the SURGE, you can take your bitch for a blood draw progesterone test three days later. This will help lessen the expense of multiple blood draws.
