Firstly, Is it Good for Canines?

Research has shown that salmon and cod liver oils are extremely beneficial to humans, but did you know they can be a fantastic addition to a dog’s diet too. Giving this your four-legged friend reduce inflammation, help prevent allergies and aid kidney function.

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. 

Ingredients: What is it?

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.

Many commercial dog food manufacturers don’t add enough of these essential nutrients into their products in order to cut costs, 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.


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 from its food usually in pellet form and it can be difficult to know just how much especially if the salmon is farmed overseas and it is also higher in saturated fats.

A good thing about sea-farmed salmon is: it is often fresher than its wild cousin because the time between harvest to the production of the oil is much shorter. It is important to choose a high-quality oil and check the label.

What About Side Affects 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;

  • Weight gain, although this can be prevented with a balanced diet and regular exercise.
  • Bad breath; the fishy odour can be prevented by cleaning your dog’s teeth (this handy guide shows you how).
  • Stomach ache
  • Nausea
  • Diarrhoea
  • Too much fish oil can cause a deficiency in vitamin E which can result in bone weakness and lameness.

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. 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.

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.

Dosage - How much should you give?

Most 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 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 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 diet.

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 I liked the Pets Purest made in the UK from Scottish salmon this 1-litre bottle is value for money and has a handy pump that dispenses the correct dosage without any mess.

Last Word

This is, without doubt, a great addition to your dog’s diet, providing numerous health benefits as well as excellent skin condition 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.

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