I bookmarked this a long time ago but handy to have: http://books.nap.edu/openbook.php?isbn=0309034965&page=44#pagetopIf I remember correctly, my 55 lb dog converts to 25 kg.......I bet if you enter your dog's weight into Google (25 lbs = ? kg), you'll get a conversion. |

Thanks for the conversion site, but I'm trying to determine if the amount of Vitamin D & Zinc in the Nutro are too much for dogs (overdose?). I'm not sure how to determine that. Bonnie weighed 21 lbs. before she got sick.

your little Bonnie is 9.5454 kilos.. so multiply the amount in the link Jac c gives by 9.5 d = 76.36 zinc= 339.62 |

Heard back from Nutro today re: amount of Vitamin D in their dry foods. They say 2000iu/kg. Is that high or normal? The necropsy for my female Jack Russell who died in June of 2008 showed mineralization indicative of Vitamin D toxicity but they would not say DEFINITELTY Vitamin D caused her death. No melamine or cyaurnic acid present. Her symptoms were the same as Vitamin D toxicity as well as Zinc toxicity. Zinc levels in the Chicken & Rice dry food were 88mg/kg. Depending on which authority you look at, one says too much zinc, the other says 'within guidelines'. Trying to pin it down before I spend MORE money I don't have on food & slide analysis.
Anybody have any ideas, suggestions, etc?
Maybe I'm being dense, but the zinc levels in the food are 88mg/kg. Doesn't that mean 88mg per kg of food, not dog? (Hated math) |

I did not do well in English as you will likely guess;) yes that is 88mg per kilogram or 2.2 lbs ... In the case of many foods they have roughly 4 oz to a cup of food wt ... so it would take roughly 10 cups to make a kilogram |

mary blonde,
Yes, the amounts of Vitamin D and Zinc you quoted are per kg of the food. So, you have to convert that number to what amount would be in the amount of food you feed. Then, you have to find out how that relates to the safe levels to feed the dog. I will look to see if I can find any reference to what those safe levels are.

Mary Blonde, you might want to consider contacting Don Earl with the Pet Food Product Safety Alliance at http://www.pfpsa.org/. He was the person who had some of the original food tested and found the excessive vitamins. He would be able to help you convert all of it and figure out how much the levels your food had in comparison, etc PLUS Im positive he would want to know what you were told about what they found. If you contact him, can you let us know what he says? Don was always good at getting us information and I would like to know his take on this too. Best of luck to you and Im sorry for the loss of your doggy. |

Mary Blonde from that link the amount of vit. d is 500 with 5,000 max! Sheesh- they recommend 1-3000 IU for women and think how much we weigh compared to a tiny dog or cat. 2,000IU does sound like quite a bit for your size baby.

Does not matter if they cannot make their own. An overdose is harmful to anyone - human or animal.

If you click on the individual nutrients in the chart in the above link, it gives more information regarding minimum amounts to be fed and toxic amounts.
ETA - The detail for each nutrient gives the minimum amount to be fed per pound of food (dry matter basis) which may make it easier to understand.

I sent the info to Don yesterday and this is his response: Doing some quick research on the numbers, I found this:
http://ods.od.nih.gov/factsheets/vitamind.asp
Great site for everything you could want to know about vitamins, huh? I was
impressed.
The site gives 2000 IU (50 mcg) as the upper tolerable limit for a person.
The NRC recommendation for a 33 pound dog is 3.4 mcg per day. As close as
I've been able to calculate food requirements, a 33 pound dog would eat
about a pound of food a day, give or take a bit, for most dog food formulas.
On that basis, 2000 IU per kilo of food, would be a daily dose of about 23
mcg for a 33 pound dog eating a pound of food a day. That would be on the
order of 7 times the NRC recommendation.
In terms of people values, a person taking 50 mcg per day would be at around
10 times the recommended levels. IMO, you'd be pushing the upper limits at
that much per kilo of dog food, but I don't know if it would be considered
outright toxic at that level.
Zinc at the level you mentioned would be about two and a half times the NRC
recommendation, which is probably safe or at least not immediately
dangerous.
You're welcome to post or pass along the above if you like. Maybe it will
stimulate additional discussion and research.
Regards,
Don |
