What Is DHA in Dog Food? Vet-Reviewed Benefits, Drawbacks & FAQ

dog eating dog food

DHA is an omega-3 fatty acid that is found in fish oil. It is a popular ingredient in dog food because it is thought to have many health benefits. These include reducing inflammation, improving heart health, and aiding in cognitive function.

While there is evidence to support these claims, there is also contradictory research. Therefore, it is important to weigh the pros and cons of feeding your dog a food that contains DHA before making a decision. Let’s take a closer look at this ingredient in this article.

What Is DHA?

DHA is an essential fatty acid that is important for the health of your dog. It is found in fish oil, is a major component of the cell membranes, and is necessary for the proper development and function of the nervous system. DHA also promotes healthy skin and can make your dog’s coat shiny and soft. It’s commonly found in larger amounts in puppy foods than in adult dog food formulas, but any dog food that contains fish or fish oil likely has some amount of DHA.

The 3 Benefits of DHA for Dogs

Let’s look at all the ways that DHA can be beneficial for dogs.

1. Inflammation Reduction

One of the most well-known benefits of DHA is its role in reducing inflammation. While inflammation is a natural response of the body that can occur when the dog is injured or infected, DHA has been shown to reduce its severity in both humans and dogs. This can be beneficial in cases of injury, arthritis, and other conditions that cause inflammation.


2. Reduced Risk of Heart Disease

DHA has been shown to improve heart health in dogs. It can help lower blood pressure and cholesterol levels, which can reduce the risk of heart disease.


3. Improved Cognitive Function

DHA is essential for cognitive function. It has been shown to improve memory and learning in both humans and dogs.

The 2 Drawbacks of DHA for Dogs

While there are many benefits of DHA for dogs, there are also a couple of drawbacks.

1. Upset Stomach

One of the most common side effects of feeding your dog too much fish oil as a source of DHA is an upset stomach. This is usually mild and goes away on its own, but it can still be uncomfortable for your pet. If your pup has a sensitive stomach, you may want to gradually introduce this ingredient and avoid feeding them food that contains a large amount of fish oil.

2. Sustainability

A potential drawback of DHA is that it has historically been sourced from fish oil, which significantly impacts fish stocks. However, alternative sources of DHA are starting to be used. Algae seems to be a promising source, and some dog food manufacturers have started to use it.

Where Does the DHA in Dog Food Come From?

Most DHA in dog food comes from fish oil. It’s a good source of omega-3 fatty acids, which are essential for canines. However, it is important to note that not all fish oils are created equal. Some are better quality than others, and they may contain more or less DHA. It is important to choose high-quality fish oil and/or food for your dog.

Since using fish oil as a source of DHA is not sustainable, we can expect to see more DHA from alternative sources, such as marine algae, being used in the near future.
