Cod Liver Oil for Dogs: What It Does and How to Use It

If you’ve heard about cod liver oil for people, you might wonder if it’s good for dogs too. The short answer is yes – it can be a handy supplement for many pups. It’s packed with omega‑3 fatty acids, vitamin A and vitamin D, which help skin, coat, joints and the immune system.

Why Give Your Dog Cod Liver Oil?

First, the omega‑3s (EPA and DHA) calm inflammation. That means less itching, fewer hot spots and smoother skin. Dogs with arthritis often move more comfortably when they get a steady dose.

Second, the vitamins support bone growth and eye health. Young dogs growing fast need extra vitamin D, while older dogs benefit from the immune boost that vitamin A provides.

Third, the oil adds a shiny coat. A few drops mixed into food can turn a dull, dry coat into a glossy one that’s easy to brush.

How Much Should You Give?

Dosage depends on your dog’s size. A common rule is one drop per pound of body weight every day, but many brands list a specific amount on the label. For a 20‑pound dog, 20 drops (about a teaspoon) is typical. Start with half the dose for the first week to see how your dog reacts, then increase to the full amount.

Always give the oil with food. It reduces the chance of stomach upset and helps the nutrients absorb better.

Choosing a Safe, Quality Product

Not all cod liver oil is created equal. Look for these signs of a good product:

• Purity testing: The label should mention third‑party testing for heavy metals and contaminants.
• Freshness: A dark bottle with a tight seal protects the oil from oxidation.
• Added flavors: Some oils are flavored with salmon or chicken to make them more appealing to dogs.

If the price seems too good to be true, it probably is. High‑quality oil costs a bit more, but it’s worth the safety.

Safety Tips and When to Skip It

Too much cod liver oil can cause vitamin A toxicity, leading to bone pain or digestive issues. Stick to the recommended dose and avoid giving extra vitamin supplements that also contain A or D.

Dogs with pancreatitis, gallbladder disease, or clotting disorders should stay away from any oil unless a vet says otherwise. If your pup is on medication, especially blood thinners, check with your vet first.

Watch for signs of an allergic reaction – itching, swelling, or vomiting – and stop feeding the oil if they appear.

Practical Tips for Adding Oil to Your Dog’s Routine

Mix the drops into wet food, kibble, or a homemade meal. If your dog dislikes the taste, try a frozen treat: blend a small amount of oil with plain yogurt, freeze in an ice cube tray, and give one cube as a snack.

Keep a small spoon or dropper handy so you can measure the right amount every day. Store the bottle in the fridge after opening to keep it fresh longer.

Most dogs love the added flavor, so you’ll likely see them finish their bowl faster.

Bottom Line

Cod liver oil can be a simple, effective way to support your dog’s skin, joints and overall health. Choose a reputable brand, follow the proper dosage, and keep an eye on any side effects. When used correctly, it’s a win‑win for both you and your furry friend.
