Nature’s Logic

Hi Karen,

What are your thoughts on Nature’s Logic dog food?


OK… I may be WAY off here, but these things are that peeks my curiosity and makes me say hhhmmmmmm! As a supplement additive the montmorillonite probably would be good b/c of all the trace minerals BUT using clay as one of the top 10 ingredients in their food? I’m not so sure. It also does NOT say human ingredients anywhere that I looked.

I looked at the beef dinner.

The first thing that jumped out at me as the SEVENTH ingredient was the Montmorillonite. (The FORTH ingredient in the chicken dinner ). What exactly is that?????? I didn’t know! It is sold as a livestock feed additive.

Here is what Wikipedia says in quotes.

“Montmorillonite is a very soft phyllosilicate group of minerals that typically form in microscopic crystals, forming a clay.” What is phyllosilicate or silicate???

“Silicate minerals all contain silicon and oxygen.” what is silicon and is it required additive or a filler in dog food???

“Silicon is an essential element in biology, although only tiny traces of it appear to be required by animals.[5] It is much more important to the metabolism of plants, particularly many grasses, and silicic acid (a type of silica) forms the basis of the striking array of protective shells of the microscopic diatoms.”

I gotta look into this further!

MILLET: It’s rich in B vitamins but I remembered something about millet (2nd ingredient) and this is what it was. “As none of the millets are closely related to wheat, they are appropriate foods for those with coeliac disease or other forms of allergies/intolerance of wheat. However, millets are also a mild thyroid peroxidase inhibitor and probably should not be consumed in great quantities by those with thyroid disease.” Although a good flour type staple for people who are allergic to wheat, what would this do to a dog with hyper or hypo thyroidism?

BREWER’S YEAST-4th ingredient probably for a protein source: Considerations: Bloating in dogs according to “If you are suffering from a dangerously impaired immune system, do not take brewer’s yeast unless instructed by your doctor.” from

Check with your veterinarian before beginning a brewer’s yeast regimen. Diabetic dogs should not take brewer’s yeast as it can interfere with the insulin cycle. from

“You can experience bloating and extreme gas while taking brewer’s yeast according to”

This statement is for humans but it makes me wonder about dogs. “According to, brewer’s yeast should be avoided if you have high levels of uric acid or gout. If you have an existing allergy to mold, brewer’s yeast might not be for you. If you are pregnant or nursing, ask your health care provider if you should be taking brewer’s yeast. ”

I know Dr. Pitcairn recommends Brewer’s but only a very small amount compared to this.

That is just a quick look at it.

Regards, Karen ;~)

    Thanks Karen for the information! I just saw that this food had been getting many discussions online lately, and wanted to hear someone’s opinion who actually knows what they are talking about. 🙂

    So, what foods have you fed your dogs and would recommend?

    So what kind of food would you recommend for a Sheltie with pancreatitis and severe food allergies? I give him Prescription Diet W/D and Low-Fat Innova. If he gets only the Innova he gets real bad diarrhea.

    I have fed them ALL and then some 15 years ago! :~) Since then, I’ve been feeding raw food after extensive research. I started and learned on our first 2 GSD’s, one who was suppose to die by age 3, and she didn’t until almost her 12th birthday. Since the other 2 passed, we have 2 more. A 3 year old female, Teeghan and an 18 month old male Doogan. Their parents ate raw food and they have eaten raw since 3 weeks of age. I know that everyone is not cut out for doing a raw diet but, there are some good “clean” dry foods out there. I’ll write you and explain more after this holiday weekend if that is ok.
    Best regards, Karen :~)

    >Best Regards, and Happy Thanksgiving! Karen :~)
