Mendota Natural Supplements for Dogs: The Complete Range

A complete guide to the Mendota Pet natural supplement range for dogs — Retrieve Skin & Coat, Glucosamine 2X, Aches & Discomfort, Enzymes, Chew Stopper and Ear Wash. Ingredients, dosing by weight, and how to choose.

Dermagic Europe stocks the full Mendota Pet natural supplement range for dogs — six products covering joints, mobility, digestion, skin and coat, ear hygiene and destructive chewing. This guide covers what each one contains, who it is for, and exactly how much to give by body weight.

Dermagic has always been a topical business. Sulphur, aloe, shea butter — things you put on a dog. But skin is fed from the inside as well as treated from the outside, and a dog that cannot digest its food properly will keep producing a poor coat no matter what you bathe it in.

That is the gap the Mendota range fills.

Who Mendota Pet are

Mendota Pet manufactures natural pet health products in the United States under the Retrieve Health name, founded by Tim Fisher. The formulations follow a consistent philosophy that is worth understanding before you pick one:

  • Single-purpose formulas. Each product does one job. There is no everything-in-one multi-supplement in the range.
  • Named actives at stated inclusion rates. You can read exactly what is in the bottle and how much.
  • The processing matters as much as the ingredient. Mendota’s own published argument for its glucosamine is not that it contains glucosamine — everyone’s does — but that it is micronised finely enough to actually be absorbed. More on that below.
  • Made in the USA, and imported into the EU by Dermagic Europe.

Retrieve Skin & Coat — Omega 3, 6 and 9

Skin is your dog’s largest organ. It is the barrier against injury and infection, it regulates internal temperature, and it acts as a reservoir for certain nutrients. It is also the first thing to look poor when the diet is short of essential fatty acids.

Retrieve Skin & Coat is an Omega 3, 6 and 9 dietary supplement built to address that directly. Mendota’s stated effects are:

  • Decreased shedding
  • Removal of dry skin flakes
  • Reduced excessive scratching
  • Improved overall wellness

This is the Mendota product that pairs most naturally with Dermagic’s own work. If you are running a topical protocol on a dog with chronic skin allergies or a dull winter coat, the omega oils are what the body uses to rebuild the skin barrier underneath the treatment.

Give it time. Coat quality is a function of the hair growth cycle, and you are typically looking at six to eight weeks before the difference is obvious in the brush.

Retrieve Glucosamine 2X — joints and cartilage

The most technically interesting product in the range, because Mendota makes an argument most joint supplements do not.

Active ingredients: Glucosamine HCL 99% (shellfish source), Yucca Schidigera, Chondroitin Sulfate, Calcium Ascorbate (from Ester-C), d-Alpha Tocopheryl (Vitamin E), Omega-3 and Omega-6 fatty acids.

What it is claimed to do: relieve swelling and inflammation in the joints, support repair of connective tissue such as cartilage and ligaments, help lubricate hips and joints, and protect against cellular damage through its antioxidants.

Why particle size is the whole argument

Glucosamine trials are notoriously inconsistent — some show a clear benefit, others show almost none. Mendota’s explanation is that the trials rarely record how the glucosamine was prepared, and that this is the variable that decides whether the dog can use it at all.

There are three ways to reduce glucosamine to a usable particle:

  1. Crushing and cutting — hammer-type impact and blades. Cheap, and it leaves particles so large that the dog’s ability to break them down into a usable amino sugar is very poor. It still allows “contains glucosamine” on the label.
  2. Traditional micronisation — milling and grinding in rotating drums with steel spheres. Better.
  3. Supercritical fluid micronisation — the modern pharmaceutical method, dissolving the solid under high pressure and temperature. Particles come out a few hundred nanometres across. Mendota cites absorption rates thousands of times better than crushing and hundreds of times better than grinding.

Retrieve Glucosamine 2X is built on the third method. Whether or not you accept the multipliers, the underlying point is sound and rarely made: with glucosamine, the number on the label tells you very little on its own.

The chondroitin is sourced from bovine trachea, and is included because chondroitin keeps cartilage healthy by absorbing fluid — which is the mechanism behind glucosamine’s shock-absorbing effect as the joint loads and unloads with every step.

Dosing — Retrieve Glucosamine 2X

Chewable tablets, 60 per bottle. Note the three-week loading phase, then a lower maintenance dose.

Retrieve Aches & Discomfort — aspirin-free relief

Where Glucosamine 2X works on the structure of the joint over weeks, this one addresses the comfort side.

Active ingredients: White Willow Bark Extract, MSM, Yucca Schidigera.

White willow is the original source of salicin — the compound that Bayer synthesised into acetylsalicylic acid and sold as aspirin in the 1800s. Its use as an anti-inflammatory goes back to Hippocrates, who advised patients to chew the bark for fever and inflammation.

Mendota’s case for the herb over the drug is that willow bark retains active compounds that were left behind when aspirin was isolated. Research at Cairo University found a willow bark extract as effective as acetylsalicylic acid at reducing inflammation despite a lower salicin content, and other work has identified antioxidant, fever-reducing, antiseptic and immune-supporting components in the bark. The practical trade-off is that willow tends to take longer to take effect than aspirin, but the effect lasts longer.

The formula is rounded out with Yucca, a herb used for inflammation and pain control that blocks the release of toxins from the intestines, and pharmaceutical-grade MSM, added to improve connective tissue, help cells retain elasticity, reduce swelling and speed recovery.

Mendota positions it as an option where owners are uneasy about aspirin: it does not cause the stomach irritation aspirin is known for, does not thin the blood, and is stated not to affect the liver or kidneys. That last point is why it is often used post-surgically.

Dosing — Retrieve Aches & Discomfort

Chewable tablets, 60 per bottle. Twice daily.

Dog weightDose, twice daily
Up to 26 lb (12 kg)½ tablet
27–50 lb (12–23 kg)1 tablet
51–99 lb (23–45 kg)2 tablets
100 lb+ (45 kg+)3 tablets

For dogs only — do not feed to cats. Mendota states white willow bark can safely be given long-term at the recommended dose; higher-than-recommended doses may cause stomach upset or nausea.

Talk to your vet first. This is a pharmacologically active herb, not an inert supplement. That is precisely why it works — and why it needs a conversation with your vet if your dog is already on an NSAID such as carprofen, is pregnant, has a bleeding disorder, or is booked for surgery.

Retrieve Enzymes, Food & Allergy Relief

This is the product most likely to surprise you, because it challenges a diagnosis a lot of owners have already accepted.

Active ingredients: Alpha-Amylase (Aspergillus oryzae var.), Lipase (Aspergillus niger var.), Cellulase (Trichoderma longibrachiatum), Protease (Ananas comosus), and Probiotics (Lactobacillus acidophilus) — a concentrated enzyme blend from vegetable sources with live, viable microorganisms.

The food allergy argument

There are four main digestive enzymes, and each acts on one thing only — one cannot substitute for another:

EnzymeBreaks downWhy it matters
AmylaseCarbohydratesQuick energy
ProteaseProteinMuscle building
CellulaseFibreConsistent stools
LipaseFatsLong-term energy

Dogs produce these themselves — but, Mendota argues, not in the quantities needed for modern commercial food, which has been pushed to ever-higher protein, fat and fibre levels. Historically some enzymes came from the food itself. They no longer do: live digestive enzymes are destroyed above roughly 118–170°F, so they cannot survive commercial pet food manufacturing.

The consequence is a dog eating a nutritionally complete diet that it cannot fully break down. The nutrients needed for healthy skin, organs and coat pass through undigested — and the resulting symptoms look very much like food allergy.

There is a second effect. The body appears to hold a finite reservoir of enzymes; if organs and glands are continually raided to supply digestion, the system eventually breaks down. Supplementing spares that reserve and reduces overall stress on the body, and the enzymes work alongside coenzymes, vitamins and minerals to improve their utilisation too.

Practically, it is a powder you top-feed over your dog’s normal food — no diet change, no elimination trial. Mendota also recommend it during diet transitions and stressful events, when digestion is most likely to be disrupted.

None of which means genuine allergies do not exist. If you are working through whether it is really an allergy or one of the three most common dog allergies, enzymes are a cheap and reversible thing to rule in or out before committing to a months-long elimination diet.

Dosing — Retrieve Enzymes

4 oz. per bottle, top-fed over the normal meal.

Retrieve Chew Stopper

Not a supplement, but part of the range, and genuinely useful if your dog is undoing your skin treatment as fast as you apply it.

Active ingredient: Rosemary (0.5%). Inactive: water and sodium bicarbonate. That is the entire formula.

Two design decisions matter here:

  • No alcohol. Most bitter sprays are alcohol-based, which stings on broken skin — exactly where you most need it. This one is water-based, so it can go onto a raw paw, a lick granuloma or a hot spot without hurting. Water-based also means it will not stain furniture.
  • No cayenne pepper. Cayenne is the usual bittering agent and it can burn. Rosemary does the job without that risk.

It can be sprayed over medication and over bandages, used indoors and outdoors, and is safe on plants. It tastes terrible. That is the point.

Where this earns its place in a skin protocol: the single most common reason a topical treatment underperforms is that the dog licks it off. A t-shirt or recovery suit handles the body; Chew Stopper handles paws, tails and dressings where fabric cannot reach.

Natural Ear Wash

Ingredients: Witch Hazel, deionised water, glycerine, boric acid, tea tree oil, polysorbate 80, echinacea extract and natural colouring.

A gentle formula designed to dissolve ear wax and flush out foreign debris. Like everything else Dermagic stocks, it is defined as much by what it leaves out:

  • No alcohol, which dries the ear canal and causes flaking and stinging. Natural tea tree oil is used instead.
  • No peroxide, which strips the ear’s natural oils and can damage the canal. Witch hazel does the cleaning instead.
  • Leaves the internal ear hairs intact, which matters for your dog’s balance — aggressive cleaners strip them.

Use as often as needed, and especially after bathing or swimming. Trapped water is the origin of a large proportion of ear infections, and thirty seconds of routine after a swim prevents a great deal of trouble later.

How supplements fit with the Dermagic System

They are not alternatives to each other, and the strongest results come from running both.

The Dermagic System is a topical protocol — cleanse, treat, target, restore. It clears the yeast, fungal and bacterial overgrowth living on the skin surface, which is what drives most chronic skin disease in dogs. It works from the outside in.

The Mendota supplements work from the inside out. Omega 3, 6 and 9 are the raw material the body uses to build the skin barrier and the coat that grows through it. Digestive enzymes decide how much of the nutrition in the bowl actually reaches that skin. Neither of those things can be applied topically.

A dog recovering from a serious skin condition — alopecia, chronic yeast, long-running allergic dermatitis — is regrowing a whole coat over three to six months. That is a genuine nutritional demand. Treating the skin topically while ignoring what is arriving through the gut is doing half the job.

Safety and common sense

A short, honest list.

  • This range is for dogs. Aches & Discomfort carries an explicit warning not to feed it to cats. Glucosamine 2X is labelled for dogs only. For cats, use the Dermagic feline range topically and speak to your vet before giving anything orally.
  • Check with your vet before combining with prescribed medication — especially Aches & Discomfort alongside an existing NSAID.
  • Dose by current weight, not by how big your dog looks. Weigh at the vet if you are unsure; the bands are narrow at the small end.
  • Introduce one product at a time, a few days apart, so you can tell what is helping.
  • Give it long enough. Glucosamine has a deliberate three-week loading phase before maintenance. Coat change follows the hair growth cycle. Judging any of these at two weeks will tell you nothing.
  • Read the label on the bottle you receive. Manufacturers reformulate. The label is always the authority; this guide reflects the product information published at the time of writing.
  • Supplements are not a diagnosis. A dog that is suddenly lame, in obvious pain, or losing coat rapidly needs a vet, not a supplement.

Where to start

If your dog has a skin or coat problem, start with Retrieve Skin & Coat and add Retrieve Enzymes — those two together address both the supply of essential fatty acids and your dog’s ability to absorb them, and they sit underneath any topical work you are already doing.

If your dog is slowing down, start with Retrieve Glucosamine 2X and run the full three-week loading dose before you judge it. Add Retrieve Aches & Discomfort if there is visible discomfort to manage alongside the structural support, once your vet has cleared it.

The Ear Wash and Chew Stopper are inexpensive and belong in the cupboard of any dog that swims, or any dog under treatment that will not leave itself alone.

Frequently asked questions

What is Mendota Pet?
Mendota Pet is a US manufacturer of natural pet health products, sold under the Retrieve Health name and founded by Tim Fisher. The range is made in the USA and built around single-purpose formulas — joints, mobility, digestion, skin and coat — using named active ingredients at stated inclusion rates rather than broad multi-supplements. Dermagic Europe stocks the full range in the EU.
What products are in the Mendota range at Dermagic Europe?
Six products. Four are given to the dog — Retrieve Skin & Coat (Omega 3, 6 and 9), Retrieve Glucosamine 2X (joint support), Retrieve Aches & Discomfort (white willow bark for everyday stiffness) and Retrieve Enzymes, Food & Allergy Relief (digestive enzymes and probiotics). Two are used on the dog — Retrieve Chew Stopper (a bitter deterrent spray) and the Natural Ear Wash.
Are Mendota supplements safe for cats?
No. The range is formulated and labelled for dogs. Retrieve Aches & Discomfort carries an explicit warning not to feed it to cats, and Retrieve Glucosamine 2X is labelled for use in dogs only. If you have a cat with a skin problem, use the Dermagic feline range instead and speak to your vet before giving any oral supplement.
Which Mendota supplement should I start with?
Match the product to the problem. Shedding, flaking and a dull coat point to Retrieve Skin & Coat. Stiffness getting up, reluctance on stairs or a slowing older dog points to Retrieve Glucosamine 2X. Loose stools, wind, or so-called food allergies point to Retrieve Enzymes. Recurring ear wax and post-swim ear trouble points to the Natural Ear Wash. Chewed furniture, paws or bandages points to Chew Stopper.
How long before I see results from a dog joint supplement?
Glucosamine works structurally rather than as a painkiller, so it is not immediate. Retrieve Glucosamine 2X uses a higher loading dose for the first three weeks precisely because saturation takes time, then drops to a maintenance dose. Owners typically look for a change over four to eight weeks of consistent daily dosing. Stopping at week two is the most common reason a joint supplement appears not to work.
Is white willow bark safe for dogs?
White willow bark is the natural source of salicin, the compound aspirin was originally derived from, and Mendota formulates Retrieve Aches & Discomfort around it as an aspirin-free option that does not thin the blood or burden the liver and kidneys the way aspirin can. The manufacturer notes it can be given long-term at the recommended dose, and that higher doses may cause stomach upset or nausea. Because it is pharmacologically active, talk to your vet before giving it — particularly if your dog is already on an NSAID such as carprofen, is pregnant, or has a bleeding disorder.
Does my dog really have a food allergy?
Often not. Mendota’s position is that many dogs diagnosed with food allergies are actually struggling to digest modern high-protein, high-fat, high-fibre commercial diets, because the natural enzymes in the ingredients are destroyed by heat during manufacture. Retrieve Enzymes replaces those enzymes and adds probiotics, top-fed over the normal food. It is worth trying before an elimination diet, but a genuine allergy still needs a proper veterinary work-up.
Can I give more than one Mendota supplement at the same time?
Yes, and several are designed to be combined — Skin & Coat with Enzymes is a common pairing for a dog with poor coat condition and inconsistent stools, and Glucosamine 2X with Aches & Discomfort covers both the structural and the comfort side of an arthritic dog. Introduce one at a time over a few days so you can tell what is doing what, and check with your vet before stacking anything on top of prescribed medication.
Do Mendota supplements contain any common allergens?
Retrieve Glucosamine 2X does. Its glucosamine is shellfish-derived, and the inactive ingredients include fish oil, non-fat dry milk and whey — avoid it if your dog reacts to shellfish or dairy. Retrieve Enzymes uses a vegetable-source enzyme blend with a bromelain-family protease from pineapple. Chew Stopper is water, sodium bicarbonate and 0.5% rosemary. Always read the current label on the bottle.
Do supplements replace the Dermagic System for a skin problem?
No — they work on a different layer of the problem and are strongest together. The Dermagic System is a topical protocol that clears the yeast, fungal and bacterial overgrowth sitting on the skin. Retrieve Skin & Coat and Retrieve Enzymes work from the inside, supplying the omega oils that build the skin barrier and the enzymes that let your dog absorb nutrients from its food. Treat the skin topically, support it nutritionally, and you are working both ends of the same problem.
