GnRH Ovulation Shot (LHRH-A3) – Fast Ovulation Trigger for Dogs .25mg
The GnRH Ovulation Shot (LHRH-A3 25 µg) is one of the strongest tools in a breeder’s hormone kit. This injection releases the natural LH surge needed to trigger ovulation, correct progesterone plateaus, and regulate difficult or abnormal heat cycles.
Dogssuppliesrus calls this the Ovulation Shot because it gives breeders predictable timing, more successful breedings, and better litter outcomes — especially with females that refuse to ovulate on time.
This 25 µg dose is perfect for small–medium dogs and normal, uncomplicated cycles. Safe, fast-acting, and widely used by professional kennels.

USES (ALL PURPOSES)
This shot can be used for:
1. Triggering Ovulation
• When progesterone rises but the female refuses to ovulate
• When she “sits” at 4–6 ng/ml for 1–2 days
• For timed or shipped/AI breedings
2. Silent Heat
• No swelling
• No bleeding
• No flagging
• But follicles are growing internally
GnRH forces the cycle into visible, fertile estrus.
3. Split Heat
• Starts heat
• Stops heat
• Restarts later
GnRH pulls her into a normal fertile heat.
4. Plateaued Progesterone
If progesterone won’t move past the mid-range, GnRH kicks her into ovulation.
5. No Ovulation / Weak Ovulation
Some females grow follicles but fail to rupture them.
GnRH fixes that.
6. Synchronization (Multi-Female Kennels)
Used to keep multiple females on similar cycles or to sync a female to a preferred male’s schedule.
7. Planned Breedings
For breeders who want: • Predictable breeding windows
• Perfect timing for AI
• Less progesterone testing
• Higher conception rates

DOG DOSAGE GUIDE (LHRH-A3 25 µg)
This is the brown-box dose strength.
1. Triggering Ovulation (MOST COMMON)
• 1 full vial (25 µg)
Give once when progesterone hits 4.5–6.0 ng/ml.
Ovulation occurs 24–48 hrs later.
---
2. Silent Heat
• 1 vial (25 µg)
Females typically show visible heat within 24–72 hrs.
---
3. Split Heat
• 1 vial (25 µg)
Use when heat has stalled.
Cycle reactivates within 24 hrs.
---
4. No Heat / Anestrus
• 1 vial
Often followed by visible heat within 5–7 days.
(Some hard cases may need a second dose after 5–7 days.)
---
5. Synchronization
• 1 vial per female
Given the same day to all females.
Brings cycles into alignment within the same week.
---
6. Planned Breeding / Precise Timing
• 1 vial
Give at P4 4–6 ng/ml, then do:
• AI at 24 hrs
• Second AI at 48 hrs
This is the highest-success protocol.

BREED SIZE NOTES
• Toy–Small Dogs: 25 µg is ideal
• Medium Dogs: 25 µg works well
• Large–XL Dogs: 25 µg still works, but the 0.1 mg green-box version is stronger (4× potency)
