"The Thinking Person's Pet Food"™ – Since 1979
I feed my dog a quality dry commercial food for half his diet and homemade for the other half. I am concerned about the vitamin D in this supplement as I have read by an expert that D should not be added to a commercial diet. Can you tell me your opinion on this, and also can I get the exact amounts of B complex, E, and C in this diet? Thank you.
I'm sorry I just sent an email and I did not reference which supplement I was talking about - it is the C-Biotic supplement. Thank you.
Thank you for your letter.
The supplements and diets are formulated using the natural foods canines adapted to in the wild over eons of time. We, based upon Dr. Wysong's expertise and our 35 years of experience feeding hundreds of thousands of animals through multiple generations, do not agree that canine diets and supplements should not contain vitamin D.
If fed processed foods, pets can be deficient in this vitamin due to the effects of food processing.
I changed over to your foods to support the health of my cats, which I was particularly worried about after the melamine poison pet food scandal.
I had to take one of my cats to a veterinary dentist last week; it looked to us like his lower fang was cracked. The dentist examined him, told us that he had quite a bad case of resorptive lesions in his mouth, and extracted 10 teeth. The dentist then asked what we feed him. We feed him Archetype, Beef Stew With Gravy, Vitality, and Nurture with Freeze Dried Pheasant. The dentist told us that the theory on resorptive lesions used to be that they were caused by hairballs, as in the stomach acid eroding the teeth. But he says that the new theory is that excessive Vitamin D in pet foods can also cause resorptive lesions in some cats.
His research indicated that Wysong Archetype and Beef Stew were particularly high in Vitamin D. Archetype, by his calculations, came in at 4000 IU of Vitamin D per KG of dry matter, and Beef Stew with Gravy came in at 3700 IU. He suggests that we change to a food that ideally would have less than 1000 IU of Vitamin D per KG of dry matter. Since those are hard to find, he suggested that a guideline would be no more than 1500 IU.
What is the Wysong take on all this? I have been happy with your products, and so have my cats, for awhile now. I hate to take away kitty's Archetype, especially since it is a food that is easier for him to eat now that he has had all the extractions, and he loves it so much. But I see no other recourse.
We are sorry to hear of the problems you have experienced.
We do not agree that the diets contain excess vitamin D. They are formulated using the natural foods felines adapted to in the wild over eons of time. The claim by the veterinarian would mean that the feline's natural diet is unhealthy, which of course is absurd.
That conclusion would also deny the incredible results tens of thousands of animals have had on Wysong diets for the past 35 years through multiple generations. That constitutes far better evidence than theories about vitamin D.
Additionally, if anything, pets are deficient in this vitamin due to conventional pet food processing.
Most dental problems in pets are due to feeding conventionally processed pet foods over extended periods of time leading to periodontitis and eventual resorption of tooth structure. The solution is natural food feeding, not more processed food feeding!
I would like to know if you have any advice on what to feed my cat that has tooth resorption. I have read a lot online about this and it seems some believe it could be due to the high vitamin D levels in cat food. I just purchased Aujus and Epigen 90 and wanted to know the levels and if you have any advice on other treatment for her. I don't go to the vet because they will recommend extraction and I won't do that as long as she isn't in pain which she isn't yet. Please let me know if you have any written info on this.
We are not aware of any scientific evidence that vitamin D causes tooth resorption. Vitamin D deficiency is the greater danger with modern feeding practices.
The dry matter analysis is available on the Wysong website in the learn section if you want to view vitamin D levels in the diets. The complete analysis for Epigen 90 is not available yet, however, and it not included on the chart.
For the teeth, we would recommend Wysong DentaTreat™, which utilizes the beneficial properties of cheeses, probiotics and minerals to aid in maintaining pet oral health. The alkaline nature of the cheese shield the acidity of plaque and raises pH to neutralize tooth -destroying acids. Salivary flow is also increased causing sugars to be diluted clearing them from the oral cavity. Lastly, proteins from the cheese obstruct demineralization of tooth enamel and assist in remineralization.
As for diet, the Epigen™ and Au Jus™ are good choices. You might also want to consider the TNT™ diets in rotation. In general we recommend increasing the meat protein content of their diets. This reduces the amount of starch thus reducing bacterial growth in the mouth. Aside from this benefit, an all or mostly-meat diet is what cats and dogs were designed for, so moving toward this type of diet would be ideal for them.
It is most likely you cat is experiencing periodontitis. In that case the above recommendations will also help but if there is infection associated that will not abate, extraction may be a wise choice. Otherwise the infection can seed the system systemically and cause heart and kidney disease.
