Excerpt from Small Animal Clinical Nutrition
Choline is a component of phosphatidylcholine found in membranes, neurotransmitters, acetylcholine, methyl group donor.
Deficiency: Fatty liver (puppies) increased blood prothrombin times, thymic atrophy, decreased growth rate, anorexia.
Excess dietary protein and/or high-fat foods increase the choline requirements.
The AAFCO recommended allowances for choline is 1200mg/kg DM for dogs, and RC recommends, 1,700 mg/kg for dogs.

Kibble, cooked, and raw meals that are formulated to AAFCO’s standards technically do not need additional choline supplemented. You will often see it on the ingredient list as choline chloride.
Food that is labeled “for supplemental feeding” may or may not have sufficient levels of choline. Look at the label to verify levels or contact the manufacturer for the information.
If you are feeding DIY cooked, raw, or using unbalanced commercial grinds or mixes you will want to feed food sources that contain choline. Supplements for choline are difficult to use as it causes explosive diarrhea in some dogs.
For a twenty-pound dog, half an egg per meal meets choline requirements or a quarter of a duck egg. Since it’s hard to split a raw egg, cooking it can make it easier to portion out.
