Frequently Asked Questions
Is this product made in a certified facility I can trust?
Yes. The chews are manufactured in an SQF-certified facility and carry the NASC quality seal, which verifies ingredient identity, potency, and cleanliness through third-party audit.
Does the hydrolyzed chicken flavor pose a risk for dogs with protein sensitivities?
No. Hydrolyzed chicken is broken down into smaller protein fragments that are far less likely to trigger sensitivities, which is why it is often used in elimination diets.
Is this formula free of artificial dyes, flavors, and preservatives?
Yes, the product is free of artificial dyes, flavors, and preservatives, making it a cleaner choice for health-conscious pet parents.
Has this been independently tested for quality and label accuracy?
Yes. The NASC quality seal requires independent third-party auditing of ingredients, label claims, and manufacturing processes, so what is on the label matches what is in the chew.
Is the chew dose predictable so I never accidentally over-supplement my dog?
Yes. Each chew is a fixed dose, and the 2-chew serving size is clearly listed, so you can give the same measured amount every day without the variability of powders or liquids.
Is this safe to give my senior dog every day long-term?
Yes, the formula is designed for both the 4–6 week loading phase and the long-term maintenance phase, and the ingredients have a well-established safety profile in dogs.
Can I give this to a dog recovering from orthopedic surgery without worrying about added fillers?
Yes, the formula contains no artificial dyes, flavors, or preservatives, which is exactly the kind of clean-label profile many vets recommend during post-surgical recovery.
Is this safe for a dog with a sensitive stomach?
The hydrolyzed chicken liver flavor and clean ingredient list make it a good option for many sensitive dogs, though you should always introduce any new supplement gradually and consult your vet.
Can I trust the NASC seal on a joint supplement versus an unbranded one?
Yes. The NASC quality seal is granted only after a third-party audit confirms the company meets specific standards for quality control, adverse event monitoring, and label accuracy, which unbranded products are not required to meet.
Why does SQF certification matter for a pet supplement?
SQF certification is a globally recognized food safety standard. It means the facility follows strict protocols for ingredient handling, contamination prevention, and batch consistency.
How does this compare to cheaper glucosamine chews without NASC certification?
Cheaper chews without NASC certification do not undergo independent audit, so potency, purity, and label accuracy cannot be verified. The NASC seal removes that guesswork.
Is this safer than giving my dog human joint supplements?
Yes. Human supplements may contain xylitol, different dosing ratios, or additives that are unsafe for dogs, whereas this product is specifically formulated and dosed for canine use.
How does this compare to prescription joint diets from my vet?
Prescription joint diets are formulated as complete daily food, while this is a targeted chewable supplement that can be added to your existing diet. Many owners use both, but the chew gives you a concentrated joint formula in addition to balanced nutrition.
How do I know this isn't just a marketing claim about 'vet-formulated'?
The vet-formulated status is supported by the NASC quality seal, SQF-certified manufacturing, and a published full-ingredient panel with exact milligram amounts per serving.
I'm nervous about giving any supplement to a small senior dog. Is the dose safe?
The recommended serving is based on your dog's weight, and the chew format allows for easy half-dosing when needed, but you should always confirm the correct serving with your vet for very small dogs.
What if my dog has a bad reaction, is there any quality guarantee?
The NASC quality seal requires manufacturers to monitor and report adverse events, and VetriScience stands behind its products, but you should always contact your vet and the manufacturer if you observe any reaction.
How do I give the chews to my dog each day?
Give the recommended number of chews based on your dog's weight, typically 2 chews per day during the initial 4–6 week loading phase, then follow the maintenance serving on the label. Most owners give them directly as a treat or with the regular meal.
What is the loading phase versus the maintenance phase?
The loading phase is the first 4–6 weeks, where the daily serving is higher to build up active ingredients in the joint tissue. After that, the dose is reduced to a maintenance level for long-term daily support.
How should I store the chews to keep them fresh?
Store the bag in a cool, dry place away from direct sunlight, keep the bag sealed between uses, and avoid leaving it in a hot car or humid environment for extended periods.
Is this safe to use alongside my dog's current joint medication from the vet?
The formula is designed for daily use, but you should always review the full ingredient list with your veterinarian before combining it with prescription joint medications or NSAIDs.
Will this work for both small and very large breed dogs?
Yes, the chews can be given to dogs of all sizes, though the serving size is weight-based. Smaller dogs may receive a partial chew, while giant breeds typically receive the full serving listed on the label.
What is included when I open the bag?
Each bag contains the labeled number of chews (60, 120, or 360 depending on the size you purchase), with clear dosing instructions printed on the label. Nothing else needs to be purchased separately to start the routine.
Are there any side effects I should watch for when starting this supplement?
Most dogs tolerate the formula very well, but as with any new supplement, watch for any change in appetite, digestion, or stool during the first week. If you notice anything unusual, pause use and consult your veterinarian.
Is this product made in the USA and what quality standards does it follow?
VetriScience manufactures this product in an SQF-certified facility, and the formula carries the NASC quality seal, which requires third-party auditing of ingredient identity, potency, and label accuracy.
What is the difference between a joint supplement chew and a joint prescription diet?
A joint supplement chew is a targeted, concentrated source of joint-supporting ingredients added to your existing food, while a joint prescription diet is a complete dog food formulated with added joint nutrients. The chew allows more precise dosing and can be added to any diet your dog already eats.
