This calculator is biased: it is without crop and has some simplifications.

It assumes 80% animal; 20% herbal.

Of those 80% animal it assumes:

• • 0.5 scallop
• • 0.2 rumen
• • 0.15 insides
• • 0.15 raw bones and meat.

Of those 20% herbal:

• • 0.7 vegetables
• • 0.3 fruits.

Fat within meat varies from 5% - 25% percent the amount of fat needs to be at least 15% for a dog. The rest will be enhanced via additional fat (e.g. coconut oil).

This calculator assumes a flat average of 8% fat within the meat.

The amount of food is:

• 2-4% adult animals
• 4-10% if in growth or lactating.

While growing the tendency is higher on large dogs than on small dogs:

Dog Size	Age	Multiplier
small	9 - 16 weeks	0.051
small	17 - 24 weeks	0.045
small	24 - 38 weeks	0.038
small	7-10 months	0.032
small	10-14 months	0.03
medium	9 - 16 weeks	0.054
medium	17 - 24 weeks	0.048
medium	24 - 38 weeks	0.042
medium	8 - 12 months	0.036
medium	13 - 18 months	0.03
large	9 - 16 weeks	0.06
large	17 - 24 weeks	0.054
large	24 - 38 weeks	0.048
large	9 - 16 months	0.042
large	16 - 24 months	0.036

However on adult dogs that changes:

Dog size	Multiplier
small	0.03
medium	0.03
large	0.02

Additional this calculator adds extra multiplier based on activity levels:

Activity in hours	Multiplier
1h	1.0
2-3h	1.25
3-4h	1.5
4-5h	1.75
5-6h	2.0
> 6h	2.5

When the dog is neutered or old the multiplier gets reduced by 10% (multiplier 0.9).

Supplement calculation of this calculator is simplified as well.

For algae powder we assume:

• 29.0 µg per kg when puppy
• 12.7 µg per kg when adult

Therefore this calculator concludes a step wise setting per age group:

• 9 - 16 weeks 29.0 µg per kg
• 17 - 27 weeks: 29.0 * 0.8 ~ 23.2
• < 7 months: 29.0 * 0.7 ~ 20.3
• < 10 months: 29 * 0.6 ~ 17.4
• < 1 year: 29 * 0.5 ~ 14.5
• above that 12.7µg per kg

Although various calculator assume more based on food and energy consumption we stick with that assuming a higher doses due to measurements mistakes and mood swings within a household.

For Cod liver oil it assumes:

• a flat 0.00000463 * food portion

For Omega 3 Oil it assumes:

• a flat 0.0000093 * food portion.
