Is 400 mcg Vitamin K1 supplement too much for my dog's homemade diet?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed | 12 years and 8 months old

Hello! How much Vitamin K a 20 kg dog should consume daily through diet? I'm asking this because neither AAFCO or FEDIAF guidelines have a minimum for Vitamin K, but NRC states that this vitamin should be included in diet. My dog is eating a homemade cooked diet, and the vet that designed it recommended me to give my dog 400 mcg of a Vitamin K1 supplement daily. Isn't that too much?

Hello,

That amount of vitamin K sounds appropriate for your dog.

Here is a link where AAFCO references vitamin K levels:
