Safe Upper Limits for Dog Diets

Safe Upper Limits for Dog Diets

When formulating a diet for Dogs it is important to make sure that there are no excesses for some nutrients. Safe upper limits will be integrated into the stable (1.0) release. The following tables list the safe upper limit of key nutrients for dogs based on the NRC recommended allowance.

The 1.0 release of the software will have these limits built in automatically, including the safe upper limits for NRC minimum requirement. We will use arbitrary amounts (including amounts from the FEDIAF / AAFCO industry standards) for nutrients that do not have safe upper limits. We will also allow the user to alter these arbitrary amounts.

Note that puppies have more stringent requirements (see Lysine and Calcium).

Puppies 4-14 Weeks Old & Puppies 14 Weeks and Older
​Lysine ​227 %
​Total Fat ​387 %
​Linoleic Acid ​494 %
​EPA + DHA ​2153 %
​Calcium ​150 %
​Vitamin A ​989 %
​Vitamin D ​588 %
Adult Dogs
​Total Fat ​597 %
​Linoleic Acid ​582 %
​EPA + DHA ​2545 %
​Vitamin A ​4221 %
​Vitamin D ​588 %
Late Gestation & Peak Lactation
​Total Fat ​387 %
​Linoleic Acid ​493 %
​EPA + DHA ​2153 %
​Vitamin A ​989 %
​Vitamin D ​588 %

Analyzing our Recipes

Below we see the Recipe Balancer module showing the Nutrient Summary for the adult dog recipe, "Turkey and Liver with Heart." We compare the values in the Nutrient Summary to the values in the Adult Dogs Table above. We want the values to be below the safe upper limit. The screenshot below highlights two different nutrients. The first nutrient component (EPA + DHA) is 715.34 %. This is below the safe upper limit of 2,545 % cited in the Adult Dogs Table above. So this nutrient component is at a safe level for this recipe. Total Fat, Linoleic Acid, and Vitamin D are all below the safe upper limits for adult dogs stated above. However, the safe upper limit for Vitamin A for adult dogs is 4,221 % and our recipe is 4,964.65 %; above the safety level. This recipe needs to be altered to bring this nutrient component below the safe upper limit.

Thank you! This is helpful. A few questions:
- is there a safe upper limit for protein?
- I am having trouble getting my head around the idea that consuming +500% of the daily fat requirement is healthy. How can this be?
-isn't too much liver bad? Is there a limit we can use to ensure we're not above this?
- a lot of research I've done makes it seem like a certain protein/fat/cab ratios should be followed. I am having trouble using the software and comparing it back to these, likely due to the water %. How can I better do this?
- is there a way to monitor/ understand how much fiber is too much fiber? is there an upper limit for this too?

Thank you! I am still getting the hang of this so I appreciate any guidance you can provide

Hi Brianna,

I answered your question on the forums about safe upper limit for protein.

The values for nutrients are calculated on an As Fed basis in the program. Some of the reports list proximate values as Dry Matter.

A future update will assist with auto balancing based on desired protein/fat/carbohydrate ratio. However, this is not necessary when designing an optimal diet for your pet.

There is no minimum or maximum for fiber, however the amount and type of fiber can affect nutrient absorption and fecal moisture, volume, and transit time. Our upcoming Pro version addresses diet formulation with fiber to manage disease conditions and "Dry Matter" calculations are included, alongside "As Fed" calculations.

We will also have a consumer based version of the Pro edition.

Hope this helps,

Rene
