Dry skin. Dull coat. Joint support. Everyday wellness.
If you've shopped for pet supplements lately, you've probably noticed there are a lot of oils you can add to your dog's bowl. Fish oils, omega blends, skin and coat formulas, and joint-support oils can all have a place in your pet's routine, but they're not necessarily designed for the same goal.
So how do you know which one belongs in your dog's bowl?
Let's break it down.
The best oil supplement for your dog depends on what you're hoping to support. Fish oils rich in EPA and DHA are popular for skin, coat, joints, and overall wellness, while broader omega blends may provide Omega 3, 6, and 9 fatty acids. Other formulas include additional ingredients specifically for joint and mobility support.
The key is finding the formula that best matches your dog's needs.
If you're specifically looking for a fish oil rich in EPA and DHA, Open Farm Icelandic Herring & Salmon Oil is a great place to start.
Made from Icelandic herring and salmon, this refined fish oil provides concentrated omega-3 fatty acids that support skin and coat health, joint mobility, brain function, and overall wellness.
It's also purified for quality and designed to be easy to add right to your dog's regular food.
Why We Love It
A great fit for: Pet parents specifically looking to add a concentrated source of fish-based EPA and DHA to their dog's diet.

If dry, itchy skin or a dull coat is what sent you looking for an oil in the first place, Ultra Oil Skin & Coat Supplement puts those needs front and center.
This daily oil combines sardine, anchovy, hempseed, flaxseed, and grapeseed oils to provide a blend of Omega 3, 6, and 9 fatty acids.
While it can support overall wellness too, its skin and coat focus makes it an easy option for pet parents looking for targeted everyday support.
Why We Love It
A great fit for: Dogs whose skin and coat are your biggest priority.
Not every oil supplement is primarily about skin and coat.
If your dog is getting older, lives an active lifestyle, or could use extra mobility support, Ultra Oil Joint takes a more targeted approach.
Along with its oil base, the formula includes ingredients commonly used for joint support, including glucosamine, chondroitin, MSM, collagen, Boswellia, and hyaluronic acid.
That makes it different from a traditional fish or omega oil when joints are your main reason for adding a supplement.
Why We Love It
A great fit for: Senior dogs, active dogs, or dogs who could use more targeted joint and mobility support.
Maybe you're not trying to address one specific concern. You simply want an easy daily oil that supports your pet from nose to tail.
That's where Austin & Kat Austin's Everything Oil comes in.
This versatile formula provides optimized ratios of Omega 3, 6, and 9 fatty acids to support several areas of everyday wellness, including skin and coat health, joint mobility, and cardiovascular health.
Simply add it to your pet's food or administer it directly. It's designed for both dogs and cats, making it an especially convenient option for multi-pet households.

A great fit for: Pet parents looking for a broad everyday omega supplement rather than support for one specific area.

Here's where things can get confusing.
Several oils may support some of the same areas of health. That doesn't mean they're all interchangeable.
Instead of asking:
"What's the best oil for dogs?"
Try asking:
"What am I hoping to add to my dog's diet or support?"
| If your goal is... | A great place to start is... |
|---|---|
| Concentrated fish-based EPA & DHA | Open Farm Icelandic Herring & Salmon Oil |
| Skin & coat support | Ultra Oil Skin & Coat Supplement |
| Targeted joint & mobility support | Ultra Oil Joint |
| Broad everyday Omega 3, 6 & 9 support | Austin & Kat Austin's Everything Oil |
Looking at your main goal first can make that wall of supplement bottles a whole lot less intimidating.
More isn't automatically better.
Because many oil supplements have overlapping ingredients and benefits, using several at once may provide more of certain nutrients than your dog needs.
Before combining supplements, compare the ingredients and recommended serving sizes. Our Two Bostons Team Members can also help you look at what your dog is already eating and determine whether another supplement makes sense.
If your dog has a health condition, takes medication, or has specific dietary needs, talk with your veterinarian before introducing a new supplement.
An oil supplement should do exactly what its name suggests: supplement your dog's regular diet.
Start with a complete and balanced food that meets your dog's nutritional needs, then use supplements to provide additional support based on their individual lifestyle and wellness goals.
And remember that oils add calories too. Following the recommended serving size is important, especially if you're adding an oil every day.
There isn't one oil that's automatically the best choice for every dog.
If you're looking specifically for EPA and DHA, a concentrated fish oil like Open Farm may make the most sense. If skin and coat are your priority, Ultra Oil Skin & Coat offers a broader blend. For more targeted mobility support, Ultra Oil Joint brings additional joint-focused ingredients into the mix. And if you want an everyday Omega 3, 6, and 9 supplement, Austin & Kat Austin's Everything Oil offers broad wellness support.
The best place to start is simple: figure out what you're hoping to support first.
