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
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.
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? Sometimes a lady demands a long courtship before they’ll bed down with a man.
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.
