Vitamin B12 Nutrient Guide for Dogs - Printable PDF

A recipe has to supply enough B12, and the dog also has to absorb it, and dogs with pancreas or gut problems can run low on a B12-rich diet, so low B12 doesn’t always mean the recipe is wrong. This 9-page printable guide gives you the AAFCO requirement, the calorie method for working out your dog’s minimum, and real foods ranked so you know why a few grams of liver covers a day. It also explains why absorption matters, and why most low-B12 dogs have a gut problem, not a bad recipe.

What’s inside (9 pages):

• Vitamin B12 basics: what it is, why it matters, and why absorption is half the story
• Why your dog needs B12: metabolism, blood cells, gut lining, nerves, and growth
• How much B12 your dog needs, by calories, with a simple table
• Absorption matters: intrinsic factor, the pancreas, gut disease, and inherited problems
• Too little vs. too much: poor appetite and weight loss on the low end, very low toxicity on the high end, and when to ask your vet first
• Where home feeders get B12: liver, oily fish, clams, eggs and muscle meat, and plant-based recipes
• B12 foods ranked most to least, with mcg per 100 g and per 100 kcal
• Full chart: every AAFCO-required vitamin and mineral in 7 real foods
