Choosing the correct extender size and dilution ratio helps protect semen quality, match the final insemination volume to the dog’s size, and avoid wasting product.
Once opened, extender sterility and performance cannot be guaranteed after 24 hours. Use Extender Immediately after opening.
If unopened, the extender is good until the printed expiration date.
The recommended extender ratio depends on semen concentration:
If you do not know the semen concentration, use a 1:3 ratio.
Typical canine semen concentration is often around 100–500 million/mL, with many samples falling around 200–300 million/mL.
Sources: Canine and Feline Theriogenology; Manual of Small Animal Reproduction and Neonatology
Use the dog’s size as a general guide:
Source: Minitube International
Extender amount = Final insemination volume − Semen volume
Example:
If your final volume is 8 mL at a 1:3 ratio, you would use:

Collect Semen:
💧 Use the semen collection kit to gather a minimum of 5mL raw semen or a total extended volume of 10mL.
⚪ Collect the sperm-rich fraction and discard the clear prostatic fluid.
⏳ Allow semen to liquefy for 10-15 minutes or centrifuge under low speeds.
Mix with Extender:
🌡️ Combine semen with an extender like CaniPlus AI, avoiding water or rubber products that can damage sperm cells.
Optional: Perform Semen Analysis:
🔬 Analyze semen for concentration of raw semen.
Prepare the Syringe:
💉 Depress the syringe, insert into the semen sample, and gently draw it up. Use all plastic semen-safe syringes.
Lubricate the AI Tube:
🧴 Lightly apply HR semen-safe lubricant jelly to the AI tube, avoiding the openings to prevent obstruction.
Attach the AI Tube:
🔗 Secure the AI tube to the syringe.
Secure the Animal:
🐕 Elevate the female’s hind end for the procedure.
Insert the AI Tube:
📏 Gently insert the tube, angling upwards and then horizontally. If resistance is felt, back out slightly and reposition.
Deposit the Semen:
💨 Gently depress the syringe and deposit the semen. To release the residual semen, reattach the syringe and use air to expel the remainder.
Mimic a Tie:
🤲 Simulate a natural tie using a finger or artificial penis.
Allow Semen to Travel:
⌛ Let the semen travel into the uterus for about 10 minutes, elevating the female slightly to aid movement.
