Choline for Dogs Guide

Choline for Dogs

If you own a pet, you need to feed them a diet with Choline which has been recognized as an essential ingredient in cat and dog diets.

The Discovery of choline dates back to the 1850s and 1860s when Theodore Gobley described a substance he named ‘lecithine’, after the Greek word ‘lekithos’ for egg yolk. It was in 1862 that Adolph Strecker noted that lecithin generated a new nitrogenous chemical when heated and he named ‘choline’. Read the whole history of this nutrient here.

So, what is Choline?

It is an essential nutrient that is closely related to the B-vitamin family and is also known as Vitamin B4. It is a water-soluble vitamin, meaning it is not stored in the body and needs to be consumed daily.

Forms of Choline:

Choline is available in various forms, choline chloride, lecithin, and choline bitartrate. 

Choline Chloride:

This is the most common form of choline used in pet foods. Choline chloride is produced by combining hydrochloric acid with choline. It’s available in a powder or liquid form and is easily added to pet foods during manufacturing.


Lecithin is a natural source of choline and is derived from soybean or sunflower oils. It’s available in a granular form and is often used as an emulsifier in human foods, such as salad dressings and chocolate.

Choline Bitartrate:

Choline bitartrate is produced by combining choline with tartaric acid. It’s available in a powder form and is often used as a dietary supplement in humans.

What does choline do for dogs and cats? Choline chloride uses:

Choline assists in nutrition:

Choline is a precursor to acetylcholine, which is a neurotransmitter that plays a role in muscle contraction, memory, and many other processes. Choline also helps to maintain the structure of cell membranes and is involved in fat metabolism.

Choline supports brain health:

Choline is essential for the development and maintenance of healthy brain tissue. It is a major component of the neurotransmitter acetylcholine and dopamine and plays a role in memory, mental focus, and overall brain health.

Choline protects the liver:

Choline is involved in the metabolism of fats and helps to protect the liver from toxins. It is essential for liver health and function.

Cellular health:

Choline is involved in the maintenance of healthy cell membranes and plays a role in DNA methylation. It is essential for cellular health and function.

Lipid production:

Choline is involved in the production of lipids, such as cholesterol and triglycerides. It is essential for lipid metabolism and homeostasis.

A high-choline diet is beneficial for your dog throughout his or her life. This will aid in the development of your dog’s brain and ensure excellent liver health by preventing disorders like hepatic lipidosis. Choline also aids in the maintenance of body processes such as hydration by preventing skin water loss. It also maintains healthy cell membranes, which leads to less inflammation and a healthier coat.

How much choline does your dog need?

AAFCO recommends that dogs be fed 1360 mg per kg of dog weight.

How much choline does your cat need?

Cats need a bit more Choline in their diet compared to dogs. AAFCO recommends feeding cats a minimum of 2400 mg per kg of cat on dry matter basis.

As shown in the tables above, cats need 43% more Choline in their diet than dogs.

What are the symptoms of choline deficiency?

The symptoms of choline deficiency vary depending on the stage of life. In puppies, choline deficiency can cause developmental problems, such as delays in motor skills and learning ability.

In adult dogs, choline deficiency can cause muscle weakness, liver disease, and reproductive problems. In cats, choline deficiency can cause liver disease, cognitive decline, and reproductive problems.

The symptoms of choline deficiency are:

  • memory problems
