In the early days of commercial dog food, many dogs suffered from poor skin and coat health due to a lack of essential nutrients. This issue led scientists to uncover the critical role of certain fats in maintaining overall canine health.
Omega fatty acids in particular have proven to be indispensable ... because they play a vital role in supporting various bodily functions.
These fats not only help support a healthy inflammatory response but also support various physiological processes.
There's just one problem: it's still easy to mismanage omega oils for dogs, potentially depriving them of these crucial health benefits.
That's why today we're diving into the science behind omega fatty acids, their benefits, and the best ways to incorporate them into your dog's diet for optimal health. Let's start by getting clear on omega-6 and omega-3 for dogs.
Omega-6 And Omega-3: Essential Fats For Dogs
When it comes to essential fats for dogs, two primary families stand out: omega-6 and omega-3 fatty acids.
These fats are fundamental to many bodily functions, including cell membrane formation, immune responses, and more.
Dogs can synthesize most fats internally, but they can't produce linoleic acid (LA) and alpha-linolenic acid (ALA) on their own. These fats are truly essential and must be included in their diet to ensure proper health and development.
Other omega fats, though not classified as essential, are crucial for maintaining optimal health. These include arachidonic acid (AA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). Even though dogs can synthesize these fats, having them directly in the diet supports better health outcomes.
With that in mind, let's explore the key omega fats and how to incorporate them into your dog's diet for maximum health benefits.
Types Of Omega-3 Fatty Acids
Omega-3 fatty acids are often celebrated for their ability to help maintain and support a healthy inflammatory response, making them a crucial part of a dog’s diet.
These fats also aid in the conversion of omega-6 fats into beneficial compounds.
Alpha-Linolenic Acid (ALA)
Alpha-linolenic acid (ALA) is an essential omega-3 fat that dogs cannot produce on their own, so it must be included in their diet. ALA is found in leafy plants, nuts, seeds, and certain animal products, provided those animals consume ALA-rich foods. While ALA can convert into other omega-3 fats, this process is often inefficient, necessitating direct dietary sources of EPA and DHA.
Stearidonic Acid (SDA)
Stearidonic acid (SDA) is another valuable omega-3 fat, functioning as an anti-inflammatory and promoting heart health. ALA converts to SDA with the help of the enzyme D6D, which is also involved in converting LA to GLA or AA.
Eicosatetraenoic Acid (ETA)
SDA is converted into eicosatetraenoic acid (ETA) with the enzyme elongase. ETA is known for its powerful anti-inflammatory properties and its ability to help regenerate cartilage in joints, making it beneficial for dogs with mobility issues.
Eicosapentaenoic Acid (EPA)
EPA is one of the most researched omega-3 fats and is essential for reducing inflammation and supporting the immune system. Though dogs can synthesize EPA from ALA, the conversion is inefficient, making it important to include EPA-rich foods in their diet.
Docosahexaenoic Acid (DHA)
DHA is the final product in the conversion of ALA. It is crucial for eye, brain, and nervous system health. While not directly anti-inflammatory, DHA supports overall development and health, particularly in puppies and senior dogs.
Types Of Omega-6 Fatty Acids
Omega-6 fatty acids often get a bad rap, but they play essential roles in your dog’s health.
Deficiencies in LA can lead to skin and coat issues, reproductive problems, and other health concerns.
One crucial omega-6 fat is linoleic acid (LA), which is truly essential and must be present in your dog’s diet.
Linoleic Acid (LA)
Linoleic acid is abundant in plant oils and animal fats, making deficiencies rare. Even though dogs can convert LA to other omega-6 fats, the process requires specific enzymes that might be slow or lacking in some dogs. Therefore, including LA in their diet is vital for maintaining healthy skin and coat, among other benefits.
Gamma-Linolenic Acid (GLA)
Gamma-linolenic acid (GLA) is another important omega-6 fat. LA can convert to GLA with the help of the enzyme delta-6-desaturase (D6D), along with zinc, magnesium, and vitamin B6. GLA is known for its anti-inflammatory properties and its role in hormone regulation, making it a beneficial addition to your dog’s diet.
Arachidonic Acid (AA)
Arachidonic acid (AA) is a more controversial omega-6 fat due to its inflammatory nature. While AA is necessary for initiating an immune response during injury or illness, an excess can lead to chronic inflammation. Balancing AA with other omega fats is crucial to avoid potential health issues.
Why Fatty Acid Balance Is Important
In an ideal world, your dog's intake of linoleic acid (LA) and alpha-linolenic acid (ALA) would be balanced, similar to the natural diet of wild animals. But modern diets often disrupt this balance, leading to an excess of omega-6 fats and a deficiency of omega-3 fats.
In the wild, animals typically consume a diet with an omega-6 to omega-3 ratio of 1:1 to 5:1. However, most commercially raised animals are fed grain-rich diets, which skew this ratio significantly.
As a result, many dogs consuming conventional pet food are eating diets with omega-6 to omega-3 ratios as high as 30:1. This can lead to various health issues.
Both LA and ALA require the same enzyme, delta-6-desaturase (D6D), to be converted into their respective beneficial compounds. When the diet is rich in LA, it monopolizes D6D, leaving little enzyme activity for converting ALA into essential omega-3 fats like EPA and DHA.
This enzyme competition further exacerbates the imbalance, making it difficult for your dog to benefit from the omega-3 fats present in their diet.
Conversely, a balanced intake of omega-3 fats, including EPA and DHA, supports the production of beneficial compounds, helping to support a healthy inflammatory response and overall health.
Best Fatty Acids Sources For Dogs
To give your dog a balanced intake of essential fatty acids, it's important to include a variety of sources in her diet. Each source offers different benefits and potential drawbacks, so understanding these can help you make the best choices for your dog's health.
Consider a combination of these oils below to give your pup a broad spectrum of omega-3 and omega-6 fats, along with essential minerals and vitamins.
Algal Oil: Algal oil is a sustainable and rich source of DHA, one of the essential omega-3 fatty acids. It provides a plant-based alternative to fish oil and is beneficial for dogs who may be allergic to fish.
However, algal oil typically contains only small amounts of EPA and lacks GLA and ETA, which are also important for a comprehensive anti-inflammatory effect.
Phytoplankton: Phytoplankton are microscopic marine plants that offer a rich source of EPA and other nutrients. This option is highly bioavailable, meaning it’s easily absorbed by your dog’s body.
However, phytoplankton is often expensive and supplies only a small amount of fatty acids per serving, making it a less practical option for regular supplementation.
Flaxseed Oil: Flaxseed oil provides both LA and ALA, making it a dual source of omega-6 and omega-3 fatty acids. While it’s a good option for adding these essential fats, the conversion of ALA to EPA is inefficient in dogs. Flaxseed oil also lacks GLA, an important fat.
Camelina Oil: Camelina oil is noted for its high vitamin E content, which can support overall health. It contains ALA and LA but does not provide GLA. While beneficial, it may not be sufficient as the sole source of omega fats in your dog's diet.
Hempseed Oil: Hempseed oil is an excellent source of both LA and ALA and is also rich in minerals. Unlike flaxseed oil, hempseed oil contains SDA, which converts more efficiently to EPA. It also includes GLA, making it a more comprehensive source of omega fats for dogs.
Ahiflower Oil: Ahiflower oil is a newcomer in the field of omega supplements and is highly regarded for its rich content of SDA. It provides ten times more SDA than hempseed oil and 60% more GLA, making it an exceptional plant-based source of omega fats.
Fish Oil: Fish oil remains one of the most common sources of EPA and DHA. It provides these essential omega-3s in a concentrated form, derived from fish that accumulate EPA and DHA from algae and phytoplankton.
However, fish oil can be problematic due to potential contamination with PCBs, mercury, and other toxins, and it may lack sustainability if sourced from wild-caught fish. Additionally, fish oil is deficient in GLA and contains little ETA.
Krill Oil: Krill oil offers a rich source of EPA and DHA and is known for its antioxidant properties. However, the sustainability of krill harvesting is a concern, as it impacts the food supply for various marine species. Krill oil also has limited amounts of ETA and no GLA content.
Calamari (Squid) Oil: Calamari oil is a new addition to omega-3 supplements and is derived from squid. It is rich in EPA and DHA and currently sustainable due to lower predation by depleted fish populations. However, as its popularity grows, sustainability may become an issue. Calamari oil is also lacking in GLA and ETA.
Green-Lipped Mussel Oil: Green-lipped mussels from New Zealand offer a unique and highly beneficial source of omega fatty acids. This oil is rich in ETA, a beneficial fat not commonly found in significant amounts in other oils.
Green-lipped mussels are sustainably farmed and provide a balanced source of omega-3s, including EPA and DHA, as well as essential minerals like magnesium and zinc, which aid in the conversion of omega fats.
How Much Omega-3 Do Dogs Need?
To wrap up, it's worth asking and answering "how much omega 3 do dogs need?"
While the health benefits of omega fatty acids are well-documented, AAFCO only recently established minimum requirements for dogs.
For dry dog foods, the combined EPA and DHA should be no less than 0.05% of the dry matter, while for raw foods, the requirement is 0.1g per 1,000kcal.
This translates to a minimum of 175 mg of EPA and DHA daily for every 25 pounds of your dog’s body weight. This amount typically equates to about 1,000 mg of oil per day or approximately 1/4 teaspoon per 25 pounds of body weight.
Ensuring your dog meets these omega-3 requirements will support her overall health. Make sure to maintain the right balance of omega fatty acids, and get them from a good mix of natural sources, and you'll be on the way to elevating your dog's quality of life big time.
