Sounds like similar pseudoscience to e.g Dr. Greger who often overstates the role of nutrition in human disease and promotes anti-supplement fear mongering.
In humans:
Hypercalcemia is most often caused by overactivity in the four tiny glands in the neck (parathyroid glands) or from cancer. Extra calcium in the blood affects many body systems.
How about in dogs? Unsurprisingly, same things:
https://www.merckvetmanual.com/endocrin ... s-and-cats
There are many potential causes of hypercalcemia (see Causes of Hypercalcemia in Dogs and Cats). In hypercalcemic dogs, neoplasia (lymphosarcoma) is the most common cause, followed by hypoadrenocorticism, primary hyperparathyroidism, and chronic renal failure. Other causes of hypercalcemia in dogs, in an approximate incidence order as seen in practice, include vitamin D toxicosis, apocrine gland carcinoma of the anal sac, multiple myeloma, carcinomas (lung, mammary, nasal, pancreas, thymus, thyroid, vaginal, and testicular), and finally, certain granulomatous diseases (blastomycosis, histoplasmosis, schistosomiasis). Approximately 70% of hypercalcemic dogs are also azotemic. However, azotemia is uncommon in dogs with hyperparathyroidism.

If you tried very hard I'm sure you could manage to cause disease by overdosing your dog on something (difficult by oral route for calcium), but balanced supplement mixes when measured properly into the food will not do that. As long as you can measure e.g. a teaspoon and not mix it up with a cup, you're fine. The difference between a level teaspoon with voids and a heaping one without isn't enough to cause problems.
Anti-supplement fear mongering can really be dangerous; much more dangerous than supplements are.
The closest thing to what you're describing in that entry in the Merck manual is this:
Hypervitaminosis D: iatrogenic, plants (eg, day-blooming jessamine), rodenticides, antipsoriatic cream
Iatrogenic disorders: excess calcium or oral phosphate binders
Eg. in dietary terms only Hypervitaminosis D is a problem from things the dog shouldn't be eating (flowers, creams, poisons). The rest has to do principally with medical interventions of which I doubt "dog food" counts. Only phosphate binders are specifically mentioned as caused from *oral* interventions. The sheer amount of calcium that would have to be administered to a healthy dog in a short span of time makes it an unlikely cause and I'm not seeing mention of dog foods as a risk here.
To put it into perspective search "my dog ate a whole bottle of tums" and see how not worried veterinarians are in response.
Also keep in mind that dogs commonly practice pica too, and many soils are largely composed of calcium compounds. It's just not realistic to think common minerals like this are so dangerous. Our bodies, and those of dogs, have means of up-regulating and down-regulating absorption of these things as needed.
Contrary to your claims (and the claims of companies that want to sell you very expensive dog food and slander established brands to do it), there's no reason to believe "most" or even just many of these conditions are caused by supplementation or have anything to do with diet.
Most are really caused by genetics *cough* dog breeders *cough* but that's another topic...

I could ask to please not spread this misinformation. I don't know what quacky naturopathic pet site you're getting your info from, but you can't just say that stuff... I haven't found any evidence of the claims you're making regarding dog food.
It's an inherently anti-science conspiratorial world-view to think that the writers of the Merck manual are paid of by petfood companies that are knowingly poisoning dogs with bad food, which is what you seem to be suggesting with the anti-supplement stuff.
Even that such a large company could manage such a wide-spread conspiracy seems impossible: these companies may not be perfect, but they are staffed by vets and pet lovers.
I don't want to be too harsh here, but it's weird the lengths you'll go to to defend breeders while implicitly condemning millions of people who work in the pet food industry. We seem to be witnessing a double standard is all.
Adloud wrote: ↑Thu Dec 19, 2019 8:06 amit's extremely important to pay close attention to how a dog reacts to certain foods and consult everything with your vet.
If you have expensive carpeting, yeah. Or if they're having an allergic reaction. The only likely reason dogs would be suffering under a remotely adequate diet would be bad genetics thanks to inbreeding which gives them cancer and other actually common causes of these diseases.
Adloud wrote: ↑Thu Dec 19, 2019 8:06 amNot many animals "fall over dead" when not having a proper diet. Their health might suffer severely, however, so it's something never to overlook.
If their health suffers severely, any good pet owner will be able to identify that.
For example, hypercalcemia if you're actually worried about that:
https://www.merckvetmanual.com/endocrin ... s#v4633300
Polydipsia and polyuria are the most common signs of hypercalcemia and result from an impaired ability to concentrate urine and a direct stimulation of the thirst center. Anorexia, vomiting, and constipation can also develop as a result of decreased excitability of GI smooth muscle. Decreased neuromuscular excitability may lead to signs of generalized weakness, depression, muscle twitching, and seizures.
You're going to notice that.
Wonderful, and article by Dr. Aja Senestraro, a holistic veterinarian who among other things recommends chiropractors, acupuncture, and herbal medicines for dogs.
I wasn't wrong when I guessed that you were getting all of your info from quacks.
Look, unless you're not paying any attention you're not going to miss serious clinical signs like a dog drinking HUGE amounts of water or not pooping.

That's good that you checked. The one good piece of advice in that article was to not be afraid to ask your vet questions.
Adloud wrote: ↑Thu Dec 19, 2019 8:06 amMy dog is a working-class and he doesn't react well to starches.
How do you mean he "doesn't react well" to them?
Unless your dog is a wolf dog, it's much more likely your dog has an allergy to corn or something like that.
https://www.sciencemag.org/news/2013/01 ... estication
More surprising were genes for digesting starch. Dogs had four to 30 copies of the gene for amylase, a protein that starts the breakdown of starch in the intestine. Wolves have only two copies, one on each chromosome. As a result, that gene was 28-fold more active in dogs, the researchers found. More copies means more protein, and test-tube studies indicate that dogs should be fivefold better than wolves at digesting starch, the chief nutrient in agricultural grains such as wheat and rice. The number of copies of this gene also varies in people: Those eating high carbohydrate diets—such as the Japanese and European Americans—have more copies than people with starch-poor diets, such as the Mbuti in Africa. "We have adapted in a very similar way to the dramatic changes that happened when agriculture was developed," Axelsson says.
Dogs and wolves have the same number of copies of another gene, MGAM, which codes for maltase, another enzyme important in starch digestion. But there are four key differences between the sequence in dogs and wolves. One difference causes dogs to produce longer versions of maltase. That longer protein is also seen in herbivores, such as cows and rabbits, and omnivores, such as mouse lemurs and rats, but not in other mammals, suggesting length is important to plant-eaters. These differences make the dog maltase more efficient, the researchers report.
That dogs evolved to be able to digest starches better and use them efficiently for energy isn't speculative.
You dog might have an allergy or intolerance of some kind of corn, but he doesn't need to be on a "keto" diet to be healthy.
That said, if you want to make a food with a higher portion of protein and fat and fewer carbs (not no carbs) that's pretty easy to do too. It's actually easier, because proteins and fats in plant foods correlate better with nutrient content.
A diet based around legume, nut, and seed products will naturally contain more whole food nutrients than one rich in grains like corn and rice.
Adloud wrote: ↑Thu Dec 19, 2019 8:06 amMind that many stray dogs leave short lives full of diseases, so in this case, an appeal to nature (ironically) doesn't work too well.
I'm not talking about stray dogs, I'm talking about the genetic differences dogs have objectively evolved. You're the one who originally made negative claims about the natural suitability of plant based diets for dogs; I'm just showing how that doesn't apply. Dogs are not wolves.

I hope you will try, although I don't mean to shame you if you are for some reason unable. I'm more just critical of some of the claims that come from the alternative-medicine crowd. I can only hope you'll be more skeptical of the anti-mainstream veterinary nutrition info in the future.
Adloud wrote: ↑Thu Dec 19, 2019 8:06 amIt's similar to a raw vegan diet. The benefits are scarce and implementing it is possible but extremely hard and not recommended over the alternative.
I would agree if not for prepared nutrient mixes you can buy and add to simple recipes. I think those make it much more practical and affordable.
Of course that doesn't necessarily solve the problem for cats who have much different issues.
