Firstly, Is Fish Oil Good for Dogs?

There are tons of oils touted as beneficial for dogs, from CBD oil to coconut oil and flaxseed oil, but do you really need to be buying oil for dogs. Yes! Natural oil supplements have long since been recommended for a balanced canine diet and salmon oil is one of the best,

For example, a blend of milk thistle and fish oils is said to help prevent kidney disease, some fish oils that contain EPA are thought to suppress cancer cell growth and coconut oil is known to aid digestion, support joint health and improve a pet’s coat.

Salmon oil contains a stack of great attributes to help your pooch look and feel great. As they say, a healthy dog is a happy dog, and salmon oil with all its omega 3 fatty acids could be just what you need to help promote healthier skin, reduce blood pressure, and ensure a shiny coat and general well-being! For our latest posts on how to take care of dogs, it’s here.

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 healthy 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, improve joint health and aid kidney function.

As you can imagine, these are all key elements that 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 a top-selling salmon oil for their pets. Let’s take a look at why you should be using salmon oil, what’s the safe recommended dose and what benefits you can expect to see when introducing salmon oil to your dog’s dinner.

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.

The body can’t produce enough omega 6 fatty acids, so they must be added to the diet. 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, especially if your dog suffers from allergies.

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

What is The Best Salmon Oil for Dogs, UK?

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 made from wild salmon – and one derived from farm-raised salmon, which is very different in terms of nutrition. 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 and fish oil production is much shorter. It is important to choose a high-quality fish oil and always to 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 in nutritional information.

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 salmon oil for dogs alongside a good nutritional balance in their food. You can’t just rely on fish oil alone.

What are the health benefits of fish oil supplements for Fido?

Why is salmon oil good for dogs? Well, adding EPA (eicosapentaenoic acid) and DHA ( docosahexaenoic acid) 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,
  • Lowering of triglycerides and blood pressure,
  • Assistance for dogs suffering from kidney disease,
  • Salmon oil may also slow cancer cell growth,
  • Production of collagen, resulting in stronger bones and muscles,
  • Assistance for weight loss in obese dogs.

Is Salmon Oil Good for Dogs

As you can see, there are all kinds of conditions and concerns that salmon oil, EPA, and DHA may support your dog. Whether they are low on omega 3, omega 6 fatty acids or are struggling with their joints, you may find adding wild-caught Alaskan salmon oil to their dinner gives a great boost to their skin and coat and help prevent itchy skin. Salmon oil may also help to regulate a variety of internal problems.

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

What about the side effects of fish oils?

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.

Side effects may include:

  • Weight gain, although this can be prevented with a balanced diet and regular exercise.
  • 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
  • Nausea
  • Diarrhoea

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, be they liquid form or capsule, comply with strict regulations and contain natural ingredients, ensuring you provide 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 to include in a healthy diet for growing pups as long as the correct dose is adhered to. Again, make sure you ask a vet if you are really unsure if that Alaskan salmon product will be for the best. Picking the right oil can be confusing at first!

Dosage – How Much Salmon Oil Can I Give my Dog?

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

  • 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 for dogs 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 treating 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 it in a cool place.

Choosing the right one

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

The omega 3 fatty acids in pure salmon oil are fantastic for older dogs who may suffer from joint issues. They have also been found to slow cancer cell growth and improve kidney function.

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

Out of all the salmon oils 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 how much salmon oil you need 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 dinner, providing numerous health benefits as well as excellent skin conditions and a shiny coat.

It is safe to use but essential to buy the best quality salmon oil like Grizzly salmon oil made with wild Alaskan salmon as inferior substitutes can promote weight gain and have high levels of toxins that can do more harm than good.

Salmon oil can be used for any dog, even for young puppies – as long as you administer the correct dosage. Salmon oil is perfect for elderly dogs, improves cognitive function, and reduces inflammation in painful joints.
