Quick answer: There is no single lactoferrin dose that can be safely copied across all dogs, cats and products. Research uses different species, formulations, diet concentrations and study goals. Follow the exact pet product label and ask a veterinarian when individual health conditions matter.
Why research numbers are easy to misread
A study may report lactoferrin as milligrams per kilogram of complete diet, milligrams per kilogram of body weight, or as part of a combination formula. Those are not interchangeable.
The 2026 kitten study is not a chew dosing chart
A 2026 kitten study used lactoferrin at defined concentrations in the complete experimental diet. That tells researchers what was studied under those conditions; it does not create a universal per-chew dose for household pets.
What a retail label should make clear
- Lactoferrin amount per chew or serving.
- Number of chews in one serving.
- Species and life-stage directions.
- Other active ingredients.
- Storage and expiration information.
- Cautions.
Do not scale a human or kitten number by body weight alone
Simple arithmetic ignores formulation, diet, age, absorption, medical history and the actual purpose of the studied protocol.
