T-DOG...you are right...todays dog foods do have all the extra vegan nuts and grains that supposedly are healthy but not so...the cheap dogs food from yesteryears did have lots of grain, peas and soy were not in the ingredients...below i copied off copilot...

5. Foods That DON’T Cause This Problem
Breeders who want reliable heat cycles avoid soy and heavy grains.

They typically use:

Victor Hi‑Pro Plus

Purina Pro Plan Sport

Diamond Naturals Beef & Rice

Native Level 3 or 4

Raw or fresh diets (if done safely)

These avoid the estrogen‑mimicking ingredients.

6. The Mechanism (Step‑by‑Step Logic Chain)
Soy + flax + corn → high phytoestrogen load

Grain batches sometimes → zearalenone contamination

These compounds → mimic estrogen

The dog’s body thinks it’s already in a hormone cycle

Real estrous cycle gets suppressed

Female barely comes into heat or has silent heat

  No Slim, I never do that, reason being I want to know for sure whether they have tied or not. I will leave them together to get acquainted a couple of hours checking on them every 20 minutes or so if they haven't bred yet. But usually after the first breeding they will be tied in just minutes, then I come back and separate them.

 I had a Plott female that was the same way Mike, really wanted pups out of her and never got them.

  One other female that I have just happens to be the mother of that Cypress female. she has had two normal litters and now she will act like she is coming in heat, drip a little blood for a couple of days and thats it. Will not flag or show any interest in a male. All my other females seem to have normal cycles. A hereditary  deal maybe except all my dogs are related top and bottom. Another thing I have noticed, none of my females ever come in heat around 9-10 months. The seem to come in around 15-16 months of age.

Driving and didn’t get to read over everything yet, but didn’t see it mentioned at a glance. Are you letting these dogs live together through duration of heat?

Maybe I’m just slow Reuben, most of the “cheap” feeds are the ones that typically use the soy, grain, and chicken-by -products because of their availability and being cheaper to use.  I assume you are saying that because of that the dogs are having a more regular/stronger cycles when they come in?

I have preached against soy for years, in animals and people. They have found out that babies raised on soy formula have issues. Little girls that develop/mature early are usually soy formula babies and they usually have very erratic and severe minstrel cycles. Little boys that are raised on soy formulas are prone to having “man boobs” and maturing slower/later with less masculine characteristics. The estrogen hormone works the same in all species and we all know there has to be a balance. Peas are a cousin to soy as are peanuts. I don’t think peanuts are as high in this phytoestrogen. It’s in a lot of fruits and nuts but not as high. I don’t think it’s detrimental here and there but using it consistently is the issue. I’m bay no
means an expert. This is one of those things I have looked into because of my intestinal disease and my dogs.

below I copied off of copilot...

some commercial dog foods contain ingredients that mimic estrogen or interfere with hormone signaling.
Phytoestrogens (Plant Estrogens)
These are natural estrogen‑like compounds found in:

Soybean meal

Corn gluten

Flaxseed

Pea protein

Many mid‑tier dog foods use these as cheap protein sources.

Phytoestrogens can bind to estrogen receptors and confuse the reproductive system, causing:

Delayed heat

Silent heat

Weak or incomplete cycles

Missed breeding windows

? 2. Excessive Grain-Based Diets
High‑grain foods (corn, wheat, sorghum) can:

Spike insulin

Increase systemic inflammation

Disrupt the hypothalamus–pituitary–ovary hormone axis

This can lead to irregular estrous cycles or anestrus (no heat)

I will say this as well, back in the 1970-90's i didn't feed the expensive dog foods because the expensive dog foods back then were super expensive like almost a dollar a pound...it was a rich mans dog food...and i never had any issues breeding dogs back then with the cheaper feed...I remember some were thinking it was an iodine issue once these problems started popping up...
