Pet Honesty Hip + Joint Health (Chicken Flavor), 90 soft chews Review 2026: What Does the Evidence Show?
Joint chew's ingredients have some dog evidence, but product claims outrun it — Overhyped
-
"Glucosamine and chondroitin ease stiffness"
A 2022 review that pooled dog and cat trials found a very marked non-effect of chondroitin-glucosamine products on pain and advised against recommending them for pain. The review gave no separate dog result in the text reviewed. One dog trial reported improvement, but it had 35 dogs, no placebo group and vet scoring by eye.
-
"Omega-3s support mobility"
Fish oil omega-3s have the strongest dog record of this chew's ingredients. A placebo-controlled trial in 78 arthritic dogs found less discomfort and lameness at 84 days. The chew's omega-3 amount isn't printed, so the match can't be checked. The pooled dog-and-cat review also rated omega-3 supplements as clearly pain-relieving.

"Eggshell membrane supports joint function"
One placebo-controlled trial in 51 dogs with suboptimal joint function showed better owner-rated pain and function at 1 week, but the main measure missed significance at 6 weeks. That product was a branded single ingredient, not this chew.

"Turmeric supports a healthy inflammatory response"
A placebo-controlled trial of a turmeric extract in 61 dogs found no difference on the force plate, the main objective measure. Investigators rated dogs better; owners' ratings just missed significance.
Claims vs Evidence
4 claims assessed. Support depends on the study results, formulation, and population. Matching an ingredient or dose alone does not establish a benefit.
"Eases joint stiffness due to normal daily exercise"
Stretch
Rests mainly on glucosamine, chondroitin and turmeric, whose dog evidence is thin or mixed. The dog trials reviewed enrolled dogs with osteoarthritis, not normal exercise stiffness. A pooled dog-and-cat review reported a very marked non-effect of chondroitin-glucosamine on pain. No trial of this exact chew was found in this search.
Randomised double-blind, positive-controlled trial of glucosamine/chondroitin sulfate in dogs with osteoarthritis
Randomised, double-blind, multicentre trial with carprofen as positive control; no placebo group; subjective veterinarian scoring · ingredient
Significant improvement in pain, weight-bearing and condition severity by day 70 (P<0.001); slower onset than carprofen.
Limitations: No placebo group; subjective vet scoring; small sample; abstract only.
- Species
- dog
- Participants / condition
- 35 dogs with confirmed hip or elbow osteoarthritis

"Promotes cartilage development and connective tissue support"
Stretch
A review pooling dog and cat trials reported no approach with an indication of delayed osteoarthritis progression in pets, and a very marked non-effect of glucosamine-chondroitin on pain. The cartilage-related dog signal found here is a blood marker change with eggshell membrane in one trial of dogs with suboptimal joint function.
NEM brand eggshell membrane in dogs with suboptimal joint function
Multicentre, randomised, double-blind, placebo-controlled trial · ingredient
Serum CTX-II cartilage-breakdown marker improved versus placebo at 6 weeks (47.9%, P=0.018). Pain and function results were mixed across time points.
Limitations: Short trial; single branded ingredient; a blood marker is not a cartilage outcome; abstract only.

"Supports mobility and joint and bone function"
Partial
Omega-3 fish oil and eggshell membrane have placebo-controlled dog trials with some mobility gains. This chew's omega-3 and eggshell membrane amounts are not printed, and no bone function evidence was found in this search.
EPA and DHA in dogs with osteoarthritis
Prospective, randomised, double-blind, placebo-controlled trial · ingredient
Discomfort, lameness and joint severity improved versus placebo at day 84 (p<0.05); no major side effects.
Limitations: Single trial of an oil, not a chew; abstract only; effect sizes not reported in abstract.

Joint supplement containing eggshell membrane among other ingredients in dogs with osteoarthritis
Multicentre, double-blind, randomised, placebo-controlled trial · different formulation
Supplement group improved on all main measures over time; only CBPI pain interference differed significantly from placebo (p=0.009).
Limitations: Eggshell membrane effect can't be separated; one of several measures beat placebo; different product from this chew.
- Species
- dog
- Participants / condition
- 52 dogs with confirmed osteoarthritis; 46 completed
- Formulation
- Five-ingredient supplement: eggshell membrane, krill meal omega-3s, astaxanthin source, hyaluronic acid, Boswellia extract

- Duration
- 16 weeks in dogs
- Funding / conflicts
- Not reported in the excerpt; unavailable.
Signals
- The "88% of dogs seeing improved mobility in 90 days" figure has no supporting study or method in the reviewed material.
- "Vet-recommended" and "PhD crafted, vet approved" name no vets or review process, so they are not clinical evidence.
- The 4.8-star rating from 758 reviews is customer opinion, and the same page also shows 800 reviews.
- "Our top pick for the best overall dog supplement" is a third-party editorial quote, not evidence this chew works.
- Pet Honesty is on the NASC member list with the Quality Seal, a company-level audit and not a test of this chew (nasc).
- The page prints the full ingredient list and a weight-based chew feeding table (label).
Evidence checks
Species and formulation relevance
The dog evidence rows come from dogs with osteoarthritis, except the eggshell membrane trial, which enrolled dogs with suboptimal joint function. The 2022 review pooled dogs and cats and gave no separate dog result in the text reviewed, so it is not used as a dog evidence row. The dog trials test single ingredients or different multi-ingredient products. No trial of this exact chew was found in this search, so ingredient results don't prove it works.
Label transparency
Ingredients and a weight-based feeding table are printed, but per-chew amounts of glucosamine, chondroitin, MSM, turmeric, eggshell membrane and omega-3s were not on the reviewed page. Amounts can't be compared with studied amounts.
Independent quality testing
NASC lists Pet Honesty as holding its Quality Seal, checked 2026-11-03. It is a company-level audit with random lab testing, run by an industry trade group. It does not show this product was tested; no product-specific test result was in the reviewed material.
Research funding and independence
Several supporting trials list no funder in the abstract. The eggshell membrane multi-ingredient trial was funded by Virbac. The 2022 review had no proprietary funding, but its authors disclosed prior industry work in canine osteoarthritis, including on trials in the review. No study was found that was run or funded by Pet Honesty.

Research scope and outstanding checks
Reviewed the manufacturer page, an NASC record and about 25 retrieved PubMed and PMC records from a limited set of queries covering canine osteoarthritis nutraceutical reviews and the product name, yucca and vitamin C. Many records were abstracts or partial excerpts. Not exhaustive. No dog evidence for MSM, yucca or vitamin C was retrieved. A vitamin E trial in dogs found no benefit but vitamin E isn't tied to a stated claim. Studies on drugs, injections and non-dog species were excluded; the pooled dog-and-cat review is cited as context, not as dog-specific evidence.
