Before we start reviewing the best wild Alaskan salmon oil for dogs as detailed above, let’s start looking at what you need to know about salmon oil, what the benefits are, and why it is taking off in such a big way.

Supplementing dog diets with fish and fish oil is nothing new – but the salmon oil boom is something that many dog owners will want to make sure to get involved in. Thankfully, products, supplements and food containing wild Alaskan salmon oil are more commonplace than ever before – and they’re often really affordable, too!

Firstly, Is Salmon Oil Good for Dogs?

Yes! The answer is as clear as day. natural oil supplements have long since been recommended for a balanced canine diet, however, salmon fish oils contain particular fatty acids and nutritional makeups which are worth taking notice of.

Don’t just take our word for it, or what the salmon oil supplements manufacturers have to say, either! Salmon oil contains a stack of great attributes to help your pooch look and feel great. A healthy dog is a happy dog, as they say, and salmon oil with all its omega 3 could be just what you need to help promote healthier skin, coat and general wellbeing!

Research has shown that salmon and cod liver oils are extremely beneficial to humans, but they can be a fantastic addition to a dog’s diet too. It stands to reason! Giving wild Alaskan salmon oil to your four-legged friend may help to reduce painful inflammation, help to prevent allergies and aid kidney function. As you can imagine, these are all key elements which help make up a healthy canine lifestyle, meaning wild Alaskan salmon oil might be just what you’re looking for to top off the perfect diet.

No wonder more and more dog owners are looking for the top selling oils for their pets. Let’s take a look at why you should be using salmon oil, and what levels of dosage are safe. After all, there is such a thing as too much salmon oil, and you must make sure that your dog is getting just enough – and not overdosing.

Ingredients: What Is Salmon Oil?

Salmon oil is rich in the two long-chain, omega-3 fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). Dogs that don’t receive enough of these can be prone to deficiency based health issues such as allergies, poor organ function, weak immune system and skin conditions like dermatitis.

It’s sadly more common than you think to find dogs which are low on omega 6 fatty acids in their diets, as well as omega 3. Therefore, you’ll commonly find dog foods stacking up at the supermarket boasting Alaskan salmon oil as a primary ingredient. It’s a good thing, but make sure you do plenty of research into any dog food you buy.

However, there are still plenty of foods and kibbles out there which fail to introduce enough of these salmon oil benefits. Many commercial dog food manufacturers don’t add enough of these essential nutrients into their products – sadly, this may often be in an effort to cut costs. What’s more, the stability and molecular structure of salmon is fragile, therefore, the nutrients do not survive lengthy storage in bags of kibble – so you may need to add them as a supplement to your pet’s diet.

Thankfully, as you can see from our upcoming list of the best salmon fish oils for dogs on the market, you really are spoilt for choice. Enough is enough, however – what exactly is it about this fish oil that’s so appealing to dogs and their owners?

Uses of Salmon Oil

Before you dive into buying fish oils for dogs, it’s important to remember a few distinctions.

There are two types of salmon oil – one which is made from wild salmon – and one which is derived from farmed salmon, which in terms of nutrition, is very different. Sea-farmed salmon gets omega-3 fatty acids from its food, usually in pellet form, and it can be difficult to know just how much it’s been fed – especially if the salmon is farmed overseas. You will also find that salmon oil derived from farmed fish is likely to be higher in saturated fats.

However, a good thing about sea-farmed salmon is that it is often fresher than its wild cousin, because the time between harvest to the production of the fish oil is much shorter. It is important to choose a high-quality fish oil and to always check the label. This way, you know where your salmon oil has come from, and you can be sure that you are giving your dog the healthiest blend of omega 3 fatty acids and omega 6 fatty acids, where possible. Most salmon oil supplement-based dog food should also give you a bit of a breakdown when it comes to nutritional information, calories and more.

Not all dog owners check these stats, but if you really want to give your dog the best diet possible, you’re going to need to look for healthy oil for dogs alongside a good nutritional balance in their food. You can’t just rely on fish oil alone, we’re afraid!

What are the health benefits for Fido?

Why is salmon oil good for dogs? Well, adding EPA and DHA to your dog’s diet has lots of proven benefits – and these are likely to include:

  • Improvement to the condition of both coat and skin,
  • Prevention of nasty skin allergies,
  • Easing of joint problems,
  • Reduction of inflammation associated with conditions like arthritis,
  • Regulation of a dog’s immune system and protection against illness,
  • In addition, it calms an overactive immune system, for dogs with autoimmune diseases,
  • Boosts of energy,
  • Cachexia support – this is the muscle wasting associated with chronic illness,
  • Assistance in the treatment of Inflammatory Bowel Disease,
  • Promotion of mental and cognitive development in both foetuses and puppies,
  • Improvement in the cognitive function in senior dogs,

  • Assistance for dogs suffering from kidney disease,
  • It may also possibly prevent cancer, by slowing cell growth,
  • Production of collagen, resulting in stronger bones and muscles,
  • Assistance for weight loss in obese dogs.

As you can see, there are all kinds of conditions and concerns which salmon oil, EPA and DHA may be able to support your dog with. Whether they are low on omega 3, omega 6 fatty acids, or are struggling with their joints, you may find that food containing salmon oil is not just a great boost to their skin and coat. It may help to regulate a variety of internal problems.

What’s more, the diet-boosting benefits can clearly help to benefit portly pooches looking to lose weight.

What about side effects like itchy skin?

While there are overwhelming benefits of including this in your dog’s diet, some dogs may not take to it and although fish oil allergies are extremely rare there are some risks and possible side-effects you need to be aware of. Therefore, before you introduce anything like wild Alaskan salmon or other salmon oil into their routine, it’s worth consulting with your vet.

Side effects may include:

  • Weight gain, although this can be prevented with a balanced diet and regular exercise – salmon oil may actually offset this issue in general, too.
  • Bad breath; the fishy odour of salmon oil can be prevented by cleaning your dog’s teeth (this handy guide shows you how).
  • Stomach ache – this can be a rare side effect of salmon oil despite all the coat and skin benefits.
  • Nausea – hard to tell sometimes, but be careful on the oil if your dog is showing signs of vomiting.
  • Diarrhoea – as above – go easy on the oil!
  • Too much fish oil can cause a deficiency in vitamin E which can result in bone weakness and lameness. This isn’t always easy to spot, so just be careful with your salmon oil products!

If you’re new to omega 3 supplements and salmon oil, don’t worry too much. Side effects are not common, and it is generally safe to give your dog salmon oil – but as with any pet product they are not all the same, and some cheaper products from abroad may contain high amounts of mercury or toxic chemicals. Always make sure you check ingredients and packet information before you start giving oil to your pup.

All the oils we reviewed here comply with strict regulations and contain natural ingredients, ensuring you are providing your four-legged friend with the best. They will help with skin, coat and internal issues – and if you’re worried, ask your vet for the best advice on salmon oil in general.

Can Puppies use it?

DHA which is found in salmon oil has been found to improve brain development in puppies and it is perfectly safe for growing pups as long as the correct dose is adhered to. Again, make sure you see a vet if you are really unsure if that Alaskan salmon product is going to be for the best. Picking the right oil can be confusing at first!

Dosage – How much should you give?

Most salmon oil and omega 3 supplement manufacturers include specific dosage on their packaging, so it is important to check:

  • 4ml for dogs up to 26lbs
  • 8ml for dogs from 26-53lbs
  • 12ml for dogs from 53-106lbs
  • 16ml for dogs over 106lbs

Some of the salmon oil options we have reviewed come in a pump container which dispenses 4ml doses making it easy to see exactly how much your dog is getting.

Check with your vet if you are using salmon oil to help with the treatment of a condition with your dog if used with drugs that slow blood clotting – as it could lead to increased bleeding.

Salmon oil does not last forever, so always check the best before date and store in a cool place.

Choosing the right one

The benefits associated with best salmon oil for dogs mean more people than ever are adding this nutritional supplement to their canine companion’s routine.

It is essential to buy premium quality oil as many cheaper foreign alternatives contain environmental toxins or concentrations of heavy metal.

Out of all the ones we tested, we liked the Pets Purest made in the UK from Scottish salmon oil – this one litre bottle is value for money and has a handy pump that dispenses the correct dosage without any mess. If you’re new to salmon oil and omega 3 in general, it’s a great launchpad.

Last Word

Salmon oil is, without doubt, a great addition to your dog’s diet, providing numerous health benefits as well as excellent skin conditions and shiny coat.

It is safe to use but essential to buy top quality salmon oil as inferior substitutes can have high levels of toxins that can do more harm than good. Therefore, if your pet is susceptible to allergies or skin conditions, always check in with a vet before you buy any salmon based products.

It can be used for any dog, even for young puppies – as long as you administer the correct dosage. Salmon oil is especially good for elderly dogs, improving cognitive function, and reducing the inflammation in painful joints.
