Our verdict
This liquid glucosamine oil is a pour-over option for owners who would rather mix a joint supplement into food than fight with chews, and its 4.6 star average across roughly 2,900 reviews points to a well-liked formula.
Dogs who refuse chews or tablets, and active or hyperactive pups whose owners want to support hips and joints by mixing an oil into meals.
Skip if
Your dog has a shellfish allergy, since the glucosamine here is shellfish derived, or you prefer a pre-measured chew over pouring a liquid.

The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Context, not marks against it, and our read of the data, not a lab test.
Overview
Natural Dog Company's Hip and Joint Oil comes as a 16 ounce liquid you pour over food, flavored with salmon and peas to make it easy to serve. It is built on a familiar joint stack: glucosamine HCl, chondroitin sulfate, MSM, hyaluronic acid, and manganese chelate, all formulated to support cartilage, connective tissue, and everyday mobility.
The liquid format is the main draw. If your dog turns up its nose at chews or you want to adjust the amount by body size, an oil you mix into meals gives you that flexibility. The label lists it as gluten free and sized for small, medium, and large dogs alike.
At around $22 for a 16 ounce bottle, it sits in the affordable middle of the joint category. With about 2,900 reviews averaging 4.6 stars and roughly 1,000 sold in the past month, it has a steady, satisfied following.

Performance notes
The formula leans on the well-known joint quartet of glucosamine HCl, chondroitin sulfate, and MSM, with hyaluronic acid and manganese chelate rounding it out. These are the same actives used across most hip and joint products and are formulated to support cartilage and joint comfort rather than treat any diagnosed condition. Amounts per serving are not listed on the label, so if your dog needs a specific dose, ask your vet.
What buyers say
With about 2,900 reviews averaging 4.6 stars, owner sentiment is solidly positive, and roughly 1,000 bottles sold in the past month suggests steady repeat interest rather than a one-time spike.
You pour it over your dog's regular food and mix it in, which is why many owners pick it for dogs that spit out chews or tablets. Follow the serving guidance on the label based on your dog's size, and check with your vet if you are unsure about the right amount.
Is this safe for dogs with allergies?
It is labeled gluten free, but the glucosamine is shellfish derived, so it is not a good match for dogs with a shellfish sensitivity. When in doubt about allergies, run the ingredient list by your veterinarian first.
