PetNC Hip & Joint Soft Chews are a liver-flavored dog supplement built around glucosamine, chondroitin, MSM, and several supporting ingredients. The current iHerb U.S. listing is for a 90-count, 6.3 oz (180 g) container and directs use only in dogs 18 weeks and older.
The most useful way to evaluate this product is by reading the actual amounts per chew and then applying the weight-based directions. A large dog receives several times as many chews as a small dog during the initial period, so comparing this formula with another joint supplement based only on the amount in one chew can be misleading.

Quick Verdict
PetNC Hip & Joint Soft Chews are a straightforward option for dog owners looking for a weight-dosed soft chew containing labeled amounts of glucosamine, chondroitin, MSM, hyaluronic acid, vitamin C, manganese, and black pepper extract. The label is relatively transparent about active amounts and provides separate initial and maintenance directions.
Important drawbacks are equally clear. The glucosamine is shellfish-derived, the chondroitin is porcine-derived, and the inactive ingredients include soy, cheese, liver meal, and salmon oil. The label also contains specific cautions for dogs with shellfish allergies, clotting disorders, anticoagulant use, diabetes or another condition causing high blood sugar, or a history of urinary tract stones.
This is a nutritional supplement intended to support healthy joints, cartilage, tendons, muscles, and bones. It is not an FDA-approved treatment for arthritis, hip dysplasia, pain, or any other medical condition.

Active Ingredients Per Soft Chew
| Active ingredient | Amount per 2 g soft chew |
|---|---|
| Glucosamine Hydrochloride (Shellfish) | 250 mg |
| Chondroitin Sulfate (Porcine) | 100 mg |
| Methylsulfonylmethane (MSM) | 25 mg |
| Vitamin C (Ascorbyl Polyphosphate) | 25 mg |

What the Ingredient List Tells You
Glucosamine and chondroitin are the two most prominent joint-focused ingredients by weight. PetNC identifies the source of each: glucosamine comes from shellfish and chondroitin is porcine-derived. Those source details matter for dogs with relevant allergies and for households avoiding particular animal-derived ingredients.
MSM is included at 25 mg per chew. Because the number of chews changes with body weight, the dog's labeled daily intake changes as well. For example, a 41-80 lb dog receiving the initial four-chew daily amount gets 1,000 mg of glucosamine, 400 mg of chondroitin, and 100 mg of MSM per day based on the current label.
Vitamin C and manganese are included as additional nutrients in the formula. Dogs eating a complete and balanced food may already receive essential vitamins and minerals from their regular diet, so more is not automatically better. Consider total nutrient intake when combining supplements.
Hyaluronic acid is listed at 0.5 mg per chew, while BioPerine black pepper extract is listed at 2.5 mg. Their presence makes the current formula worth checking carefully against older product descriptions that may show a different ingredient panel.
Weight-Based Directions
The label recommends a veterinarian examination before using the product. It directs an initial administration period of four to six weeks, with the option to move to the maintenance level sooner when consistent improvement is noticeable.
| Dog weight | Initial period | Maintenance |
|---|---|---|
| Up to 20 lb | 1 soft chew daily | 1 soft chew every other day |
| 21-40 lb | 2 daily, one morning and one evening | 1 daily |
| 41-80 lb | 4 daily, two morning and two evening | 2 daily |
| Over 80 lb | 6 daily, three morning and three evening | 3 daily |
The label further states that maintenance levels may be reduced to every-other-day administration once consistent improvement is noticeable. Administer the chews during or after a meal to reduce the incidence of gastrointestinal upset.
Do not estimate a dose from another PetNC product or from another brand. Follow the directions on the exact container you purchase.
Price and Cost by Dog Size
Price checked on August 10, 2026 for the United States. Price and availability may change. The iHerb U.S. price reviewed was $9.99 for 90 soft chews, or approximately $0.11 per chew.
| Dog weight | Initial daily cost | Approx. initial bottle duration | Listed maintenance daily cost |
|---|---|---|---|
| Up to 20 lb | About $0.11 | 90 days | About $0.06 per day averaged at one chew every other day |
| 21-40 lb | About $0.22 | 45 days | About $0.11 |
| 41-80 lb | About $0.44 | About 22 days | About $0.22 |
| Over 80 lb | About $0.67 | 15 days | About $0.33 |
The per-chew price looks inexpensive, but body weight substantially changes the real daily cost. Owners of large and giant dogs should compare products using the full labeled daily serving rather than bottle price alone.
The current iHerb product information reviewed does not provide a calorie amount per chew, so a verified calorie contribution cannot be calculated here.
Other Ingredients and Allergy Considerations
The current ingredient list includes ascorbic acid, brewers dried yeast, calcium propionate, canola oil, caramel color, corn starch, disodium phosphate, dried cheese, green tea extract, liver meal, maltodextrin, mixed tocopherols, natural flavors, rosemary extract, salmon oil, salt, silicon dioxide, sorbic acid, soy lecithin, soy protein, sunflower oil, vegetable glycerin, vegetable oil, water, yeast extract, and yucca schidigera extract.
That makes this a poor match for shoppers specifically seeking a simple limited-ingredient chew. It also contains several animal and plant sources worth checking when a dog has known food sensitivities. In particular, the active glucosamine is shellfish-derived, and the formula also contains porcine chondroitin, cheese, liver meal, salmon oil, and soy ingredients.
Important Label Warnings
- For dogs 18 weeks and older only.
- Not for human consumption.
- Keep out of reach of children and animals.
- Contact a health professional in case of accidental overdose.
- Do not use a container that appears tampered with or has a broken seal.
- Store in a cool, dry place and avoid temperatures above 86°F.
- Stop administration and consult a veterinarian if the dog's condition worsens or does not improve.
- Safe use in pregnant animals or animals intended for breeding has not been proven.
- Give during or after a meal to reduce the incidence of gastrointestinal upset.
The label specifically directs owners to consult a veterinarian before use in dogs with clotting disorders, dogs receiving anticoagulant medication, dogs with diabetes or another metabolic disorder causing hyperglycemia, dogs with a history of urinary tract stones, and dogs with known shellfish allergies.
What the NASC Quality Seal Means
The iHerb listing displays the NASC Quality Seal. This is relevant as a quality-program marker, but it should not be interpreted as FDA approval, proof that the supplement works for an individual dog, veterinary endorsement of the product, or evidence that its ingredients are superior to competing formulas.
Who Might Consider This Formula?
This product may fit owners who want a soft-chew joint supplement with clearly listed amounts of glucosamine, chondroitin, MSM, hyaluronic acid, vitamin C, manganese, and black pepper extract and who are comfortable following a multi-chew weight-based schedule.
It may be less suitable for dogs that need to avoid shellfish, pork, soy, dairy-related ingredients, liver ingredients, or fish sources. Owners of very large dogs should also account for the six-chew daily initial serving when comparing convenience and cost.
Buying Checklist
- Confirm that you are buying the 90-count PetNC Hip & Joint Soft Chews rather than one of the brand's numbered Hip & Joint levels.
- Check product code CEN-27591 and UPC 740985275917 when comparing listings.
- Read the physical container because formulas and packaging can change.
- Use your dog's actual weight to determine the labeled serving.
- Review shellfish, pork, soy, dairy, liver, and salmon sources if food sensitivities are a concern.
- Check other supplements and fortified foods for overlapping nutrients.
- Ask your veterinarian before use when your dog is young, pregnant, breeding, ill, taking medication, or has an ongoing mobility problem.
Frequently Asked Questions
Are PetNC Hip & Joint Soft Chews for cats?
No. This specific product is labeled for dogs only and should not be substituted for a cat-specific supplement.
How old should a dog be before using them?
The current label states that the product is for dogs 18 weeks and older only.
How much glucosamine is in each chew?
Each 2 g soft chew provides 250 mg of glucosamine hydrochloride from shellfish. The total daily amount depends on the dog's weight and whether the dog is in the initial or maintenance period.
Does this product contain chondroitin and MSM?
Yes. Each chew provides 100 mg of porcine chondroitin sulfate and 25 mg of MSM.
Does it contain shellfish?
Yes. The label identifies shellfish as the source of its glucosamine. It also specifically advises veterinary consultation before use in animals with known shellfish allergies.
Is this an arthritis medicine?
No. It is a dog health supplement formulated to support normal joint-related structures and mobility. It should not replace veterinary diagnosis, prescribed medication, weight management, rehabilitation, or other care for a dog with pain, limping, stiffness, or a diagnosed joint condition.
Can it be used long term?
The label provides maintenance directions and describes the maintenance level as an option for long-term support in healthy dogs. Long-term supplementation should still be considered alongside the dog's complete diet, other supplements, medications, health status, and veterinary guidance.
Final Recommendation
PetNC Hip & Joint Soft Chews stand out more for clear weight-based directions and a transparent active-ingredient panel than for any claim of guaranteed results. At the current U.S. price, they can be economical for smaller dogs, while the multi-chew serving required for larger dogs increases both bottle use and daily cost.
Before buying, focus on three things: your dog's weight-based daily serving, the shellfish and other animal-protein sources, and any health conditions or medications covered by the label warnings. For an otherwise healthy dog whose veterinarian agrees that a joint supplement is appropriate, this is a practical formula to compare with other products using labeled daily amounts rather than marketing claims alone.
