Laura Reeves is joined by canine reproduction expert Dr. Marty Greer to answer a listener’s question: how frequently can you breed a stud dog before semen quality starts to decline? Marty breaks down basic stud dog anatomy, what impacts semen production and why timing matters more than sheer frequency.

You’ll learn the ideal collection schedule for peak semen quality, how overuse can show up in a semen evaluation, and why progesterone timing is essential when multiple bitches are lined up. Marty also shares practical tips for supporting your stud dog through heavy breeding demand, plus smart strategies for semen collection, shipping, and long-term genetic preservation.

Heavy breeding demand is hard work metabolically, and Marty stresses that nutrition is the foundation of semen quality.

• Feed a proven, research-backed diet (she recommendsPurina Pro Plan Sport 30/20orRoyal Canin HT-42D).

• Avoid “helpful” add-ins that actually disrupt hormones — especiallyflaxseed, because it containsphytoestrogens.

• Don’t over-supplement. Most fertility supplements havelittle science behind them, and people often unintentionally unbalance an already complete diet.

Bottom line: a balanced, consistent diet supports semen volume, motility, and longevity.

Stud dogs working hard often experience:

• stress

• loss of appetite

• environmental impacts on sperm quality

Marty notes semen quality is affected by:

• being toohot or cold

• overexertion / too much stimulation

• stress from being surrounded by bitches in heat

So:

• keep him comfortable (climate control matters)

• make sure he’ssleeping

• if he won’t eat,tempt him(chicken in the bowl is fine — the goal is calories and nutrients)

Bottom line: a stud dog can’t produce quality semen if he’s not eating, resting and staying comfortable.

Instead of multiple breedings “because she’s standing,” Marty recommends:

• Require progesterone timingso breedings are targeted

• Useone breeding(maybe two), at the correct time

• Avoid exhausting the dog with daily/every-other-day breedingsbefore ovulation even happens

She emphasizes:

• ovulation typically aroundprogesterone 4–10

• peak fertility is abouttwo days after ovulation

Bottom line: progesterone timing protects the stud dog, improves pregnancy success, and prevents “emptying the tank.”
