Angel Eyes is a US brand of oral tear-stain supplements sold to fade the reddish-brown marks under a dog's eyes, and UK owners usually have to import it. The honest answer: some dogs show lighter staining over time, but the original powders worked largely because they contained a low dose of the antibiotic tylosin, and in the UK every antibiotic for animals is a prescription-only veterinary medicine. Today's cranberry-based chews are gentler, yet good evidence that any oral supplement clears tear stains is still thin, and the stains themselves are usually a tear-overflow and hygiene problem, not a nutritional one.
Tear staining shows up most on pale and white coats, the Bichon Frise, Maltese, Shih Tzu, West Highland White Terrier and many cream Cavapoos and Cockapoos, and in flat-faced breeds such as Pugs and French Bulldogs. Before reaching for anything you feed your dog, it is worth knowing that most owners get further with outside care: trimming, wiping and rinsing with something like Pure Majesty Pets Dog Eye Drops (£16 for 120 mL), a sterile, non-medicated rinse at pH 7.0–7.2 that helps lift the pigment already sitting on the fur without bleach, alcohol or fragrance. Here is what the evidence supports. If you’re comparing care needs between breeds, use Brachycephalic Dog Breeds and Small Hypoallergenic Dogs in the UK for more detail.

What is Angel Eyes for dogs?
Angels' Eyes is a line of tear-stain products, originally powders and now mostly soft chews, added to a dog's food to reduce the rusty discolouration on the fur below the inner corner of the eye. The brand became popular in the 2000s, when its powders contained tylosin tartrate, a macrolide antibiotic. After regulatory action in 2014 the antibiotic versions were withdrawn, and the current "Natural" chews list cranberry powder, Oregon grape root, marshmallow root and colostrum powder (25 mg) as their actives. For a separate nutritional-support decision, compare eye supplements and what canine research supports rather than assuming an oral supplement replaces examination or eye treatment. See why a dog’s eyes may keep watering for the details behind this part of the care plan.

Why an Examination Matters. You can use Dog Pink Eye and Ectropion in Dogs to look up the details that apply to your dog.
Two details on the current label matter for British owners. First, the chews are built on chicken meal and dried chicken liver, with sucrose, cane molasses and parabens among the other ingredients, which is worth knowing if your dog is on a vet-supervised food trial: PDSA advises feeding nothing but the prescribed diet during a trial, treats and chews included. Second, the serving guide is written in pounds; converted, it is roughly one chew a day for dogs up to about 6 kg, two for about 7–22 kg and three for 23 kg and over. If you are comparing a food-added dental product as well, use the dental powder evidence guide to distinguish daily plaque care from treatment of established dental disease.
The category matters too. Angel Eyes is an ingested product that aims to change what comes out in your dog's tears, a different approach from a cleanser you wipe or rinse onto the fur. See how blinking and tears protect a dog’s eyes for the details behind this part of the care plan.

Can you buy Angel Eyes in the UK?
When we checked in October 2026 we could not find Angels' Eyes stocked by mainstream UK pet retailers; listings were on overseas shops and online marketplaces. If you import a pet supplement, two things are worth checking. Under gov.uk rules, VAT on goods from abroad worth £135 or less should be included in the price by the seller, while above £135 VAT (and any duty) is collected by the delivery company before your parcel is handed over. And pet feed sold in Great Britain has to carry UK labelling information, such as the words "complementary feed", the name and address of the responsible business, a batch number and the ingredients in descending order by weight. A bag labelled only for an overseas market may not tell you everything you need. To see what an estimate or purchase may include, use the examples in Dog Cataract Surgery Cost UK.
What actually causes tear stains?
Porphyrins: the pigment behind the colour
The reddish-brown tint comes from porphyrins, iron-containing molecules produced when the body breaks down red blood cells. Dogs shed some porphyrin in tears and saliva, and once tear-soaked fur sits in daylight the pigment darkens to a rusty shade. It shows most on light coats and gets deeper the longer the fur stays damp, which in a British winter of wet walks and steamy central heating can be most of the day. The minerals in that build-up are what a chelating ingredient can bind, which is the idea behind our tear-stain eye drops: they use 0.15% sodium phytate to help lift the oxidised minerals behind rusty staining rather than bleaching the fur. Before attributing all the scratching to this problem, check the parasite-control side of the routine. Our flea and tick treatment comparison separates flea treatment and prevention choices from general skin-support products. For the perception side of eye function, see what colors a dog can see.
Epiphora: too many tears, or nowhere for them to drain
Most staining traces back to epiphora, the medical term for tears overflowing onto the face. It is a symptom rather than a diagnosis. It happens either because a dog makes too many tears (irritation, allergies, a lash or hair rubbing the eye) or because the tears cannot drain properly through the nasolacrimal duct into the nose. PDSA's advice for UK owners puts the two commonest everyday causes simply: short-nosed dogs, whose eyes are often exposed and irritated, and dogs with lots of hair around the eyes and nose, where that hair irritates the front of the eye. To put those observations in context, see Glaucoma in Dogs in the UK for related questions about eye care and changes to watch for.

Allergies add to it. Dogs that react to tree pollen in spring or grass pollen from roughly May to July often run their eyes as well as scratching, so seasonal staining that comes and goes with the pollen count is a clue worth mentioning to your vet. If ear care is part of the grooming routine too, the ear cleaner comparison helps you compare products without choosing solely by scent or front-label claims. For practical steps you can use when planning everyday care, see How Often to Clean Dog Ears. When comparing choices for ear care and changes to watch for, read Dog Ear Cleaners UK alongside the product details above.
Flat-faced breeds: unusual plumbing, exposed eyes
Anatomy plays a large part in Pugs, French Bulldogs and English Bulldogs. A computed-tomography study of 51 brachycephalic dogs found the nasolacrimal duct was 41–57% shorter and three to five times more steeply angled than in longer-nosed dogs, with parts of the drainage system running in an abnormal U- or V-shaped path (Sahr et al., PLoS One 2021, PMID 34492067). Interestingly, most tear fluid in those dogs escaped through an extra opening further back in the nose, which is probably why the odd plumbing does not always cause problems on its own. Add prominent, exposed eyes and a damp nasal fold, and it is easy to see why these breeds stain. For a breed-specific example of the questions to consider, see Teddy Bear Dog Breeds and Teddy Bear Dog Breeds in the UK.
UK first-opinion data from the Royal Veterinary College's VetCompass programme backs this up. In a study of 2,228 French Bulldogs under UK vet care, conjunctivitis affected 3.2% and skin fold dermatitis 3.0% in a single year, and across more than 900,000 UK dogs the odds of skin fold dermatitis were about 49 times higher in English Bulldogs, 26 times higher in French Bulldogs and 16 times higher in Pugs than in crossbreeds. No supplement changes that conformation, which is why daily cleaning and drying of the folds under the eyes matters so much in these breeds. If scratching is part of the picture, the guide to itch-relief options helps you separate relief measures from the work of finding the trigger. For background that helps put skin and coat care in context, read English Bulldog Skin Allergies and Pug Skin Allergies.

Do Angel Eyes tear-stain supplements work?
The original tylosin powders did appear to lighten staining for many dogs, which makes biological sense: wet fur under the eyes is easily colonised by yeast (Malassezia) and bacteria that deepen the staining, and an antibiotic suppresses them. That is also exactly why regulators objected: the products were delivering an antibiotic for a cosmetic goal. If odour, greasy skin or repeated irritation is also present, review the signs and next steps for dog yeast infections so that a possible yeast problem is assessed separately. Compare the current Pure Majesty Pets Skin, Ears & Paws Drops label before adding a product in this category. Use Pure Majesty Pets for a closer look at product choices and labels for supplement labels and buying choices.
If you want to look at the options in more detail, start with Antibiotics for Dog Ear Infection.
You can follow up on this point in the UK guide to yeast infections on dogs’ paws.
For the modern cranberry-based chews the evidence is far weaker. Cranberry may reduce how well some bacteria stick to tissue, but we found no good veterinary trial showing that eating cranberry extract clears porphyrin tear stains. Owners who report success are often also trimming and drying the fur, which probably does much of the work. Treat "before and after" photos with healthy scepticism, and remember that stained hair has to grow out or be trimmed before any change shows. For routine debris around an otherwise comfortable eye, compare eye cleaners for routine debris and tear stains; this is a different task from treating a painful or inflamed eye. For the nutritional-support question, compare bladder-support ingredients and product labels separately from tests or treatment for a urinary problem.
To compare cleaning and daily care, see Dog Eye Cleaner and Over-the-Counter Eye Drops for Dogs. For related questions about eye care and changes to look out for, read Dry Eye in Dogs and How to Get Something Out of My Dog's Eye.
The tylosin question: why it matters in the UK
In 2014 the US Food and Drug Administration warned the makers of several tear-stain products, including the Angels' Eyes and Angels' Glow lines, that their tylosin-containing products were unapproved animal drugs, and raised a broader concern: routine low-dose antibiotic use for a cosmetic problem can drive antibiotic resistance.
The UK position is even clearer cut. According to the Veterinary Medicines Directorate (VMD), all antibiotics for animal use in the UK are prescription-only medicines (POM-V), which can only be prescribed by a vet for an animal under their care after a clinical diagnosis. A shop-bought "supplement" containing an antibiotic is therefore not a supplement at all in UK terms; supplements are sold as complementary feed and may not claim to treat or prevent disease. Giving a healthy dog a daily antibiotic to whiten its fur is a poor trade on every level.
The practical takeaway: read the label of anything you import. If you see tylosin or tylosin tartrate, or any other antibiotic, do not use it, and talk to your vet. A cosmetic stain never justifies an antibiotic.
A gentler, evidence-informed daily routine for UK dogs
Because most staining is moisture plus pigment on the fur, management is mostly about keeping the area clean and dry:
- Wipe the inner corners once or twice a day. PDSA suggests cotton wool pads soaked in plain warm water, or eye wipes from your vet, to remove dirt, tears and crust before they stain. Our guide to dog eye boogers shows the technique.
- Keep the hair around the eyes and nose trimmed short, as PDSA recommends, so tears evaporate instead of wicking along the hair and the hair stops irritating the eye. Ask your groomer for a neat face trim between full grooms.
- Rinse away irritants and build-up with a purpose-made, sterile, non-medicated eye product rather than a harsh whitener.
- Dry the area afterwards, and again after rainy or muddy walks. A damp face is what feeds both staining and yeast.
Product quality matters. Some tear-stain removers rely on bleaching agents, peroxide or fragrance that can sting the eye. Pure Majesty Pets takes the opposite approach: our Dog Eye Drops are sterile, filtered to 10 microns and buffered to a near-neutral pH of 7.0–7.2 to match natural tears, and they combine 0.05% sodium hyaluronate, 8% aloe vera, 2% chamomile and pro-vitamin B5 with 0.15% sodium phytate, with no alcohol, bleach, peroxide or fragrance. Put two or three drops into the inner corner of the eye, or onto a clean cotton pad, then wipe along the stained fur under the lower lid; repeat daily. They will not "erase" a stain overnight and they are not a treatment; they are the daily hygiene step while you deal with the cause. For more on technique, see our dog tear stain remover guide and how to clean your dog's eyes.
Prefer an inside-out step as well? Our Advanced Vision eye & vision support drops (£25) are a plant-based liquid you add to food once a day, built around antioxidant berry extracts, turmeric and ginger to support overall eye health and help support tear-stain control from within. Like any oral product, it works best alongside daily cleaning, not instead of it, and it contains no antibiotic. To check what to look for when choosing products for supplement labels and buying choices, read Best Dog Supplements in 2026.
Oral supplement vs daily topical hygiene
| Consideration | Oral tear-stain supplement (e.g. Angel Eyes) | Daily topical hygiene (wipe + rinse) |
|---|---|---|
| How it works | Aims to change tear chemistry from the inside | Physically removes pigment, moisture and debris |
| Evidence (current formulas) | Weak; the strongest results came from the now-removed antibiotic | Consistent with how staining physically forms; recommended by PDSA |
| Main safety concern | Antibiotic-containing versions (POM-V only in the UK); chicken-based chews during food trials | Choose a sterile, fragrance- and alcohol-free, eye-safe pH product |
| Getting it in the UK | Mainly imported via marketplaces | Widely available; our drops ship free to the UK |
| What it does not fix | Duct anatomy, allergies, blocked drainage | Duct anatomy, allergies, blocked drainage |
Tear-stain options UK owners compare (checked October 2026)
| Product | Type | What it contains | UK price seen |
|---|---|---|---|
| Pure Majesty Pets Dog Eye Drops (120 mL) | Sterile eye rinse, for the inner corner and stained fur | Sodium phytate 0.15%, sodium hyaluronate 0.05%, aloe vera 8%, chamomile 2%, pro-vitamin B5; pH 7.0–7.2 | £16, free UK delivery |
| Animology Tear Stain Remover (100 mL) | Fur cleanser; the label says avoid direct contact with the eyes | Water, phenoxyethanol, decyl glucoside, disodium EDTA, under 5% non-ionic surfactants | £2.96 at VetUK |
| Angels' Eyes Natural soft chews | Oral supplement | Cranberry, Oregon grape root, marshmallow root, colostrum 25 mg, on a chicken base | Not found at UK pet retailers; import only |
| Pure Majesty Pets Advanced Vision (2 × 30 mL) | Oral eye-support drops, added to food | Antioxidant berry extracts, turmeric, ginger, herbal botanicals | £25, free UK delivery |
Neither a supplement nor a rinse corrects a blocked duct, an allergy or an eyelid problem; those need a diagnosis.
When tear staining needs a vet visit
Staining that has been stable for years is usually cosmetic. PDSA's line is a useful one: book in with your vet if your dog has recently developed tear staining, because it can be caused by an eye problem, and get an appointment as soon as possible if your dog has developed a weepy eye, which is not the same thing as old staining. Your vet can check whether the tear ducts are draining with a simple fluorescein dye test (studies have measured how long the dye normally takes to reach the nose in healthy dogs, for example Binder & Herring, Am J Vet Res 2010) and look for hairs or lashes rubbing the eye. If a duct is blocked, our guide to blocked tear ducts in UK dogs explains what happens next.

You can use The Origins of Veterinary Clinical Nutrition and Subconjunctival Haemorrhage in Dogs to look up the details that apply to your dog. For more on eye care and changes to look out for, see Dog Ear and Eye Cleaners.
See your vet the same day if you notice squinting, pawing at the eye, redness, cloudiness, or a thick or coloured discharge; these can point to infection, a scratched cornea or a blocked duct rather than simple staining. Green or yellow-green discharge especially needs prompt attention; we cover it in green eye discharge in dogs. Out of hours, call your practice's emergency service rather than waiting until Monday.

Frequently asked questions
Is Angel Eyes safe for dogs?
The current cranberry-based chews are generally low-risk for most dogs, but they are chicken-based, so check with your vet if your dog has a food allergy or is on a food trial. Older tylosin versions contained an antibiotic, and in the UK all antibiotics for animals are prescription-only, so never use a tear-stain product that lists tylosin. Ask your vet before any long-term use. If you want to explore the related questions about skin and coat care, start with Westie Skin Allergies.
Can I buy Angel Eyes in the UK?
We could not find it at mainstream UK pet retailers in October 2026; it is mainly available through overseas shops and marketplaces. If you import it, check for VAT and duty on orders over £135, and look for UK labelling information. A UK-available alternative is a daily hygiene routine with a sterile, pH-matched eye rinse.
How long does it take to see results?
Stained fur has to grow out or be trimmed, and a supplement can only affect newly grown hair, so any change is gradual whatever the product. Daily wiping and rinsing shows its effect on fresh staining sooner, because it removes moisture and pigment before they build up.
Can I just clean the stains off instead?
For most dogs, yes. Consistent outside care, meaning trimming, wiping with warm water or a gentle eye-safe rinse, and drying the area, manages tear staining with far less risk than an ingested product, and it is what PDSA recommends.
Do tear stains mean my dog is ill?
Usually not. Stable, long-standing staining is typically cosmetic. Staining that has appeared recently, a newly weepy eye, discomfort or discharge is worth checking with your vet.
Are tear-stain supplements with antibiotics legal in the UK?
No antibiotic can be sold as a pet supplement in the UK. The Veterinary Medicines Directorate classes all antibiotics for animals as prescription-only medicines (POM-V), which only a vet can prescribe after examining your dog.
