Quick answer
In the UK, most “dog eye drops” sold over the counter in Boots, Pets at Home or on Amazon UK are sterile saline or borate-buffered eye washes for daily cleansing — not medicines. Anything containing an antibiotic (for example chloramphenicol drops) or a steroid is a POM-V product under the Veterinary Medicines Regulations and can only be supplied on a prescription from your vet. For routine tear staining, dust, pollen or mild “eye boogers”, a gentle daily rinse is the appropriate first step; for a painful, squinting or cloudy eye, book a same-day vet appointment.
Daily cleansing, no prescription needed:

What you can actually buy over the counter in the UK
UK pet owners searching for dog eye drops usually land on one of three categories, and they are not interchangeable.
1. Eye washes and cleansing rinses (AVM-GSL or cosmetic). Sterile saline, boric-acid/borate buffers, sometimes with euphrasia (eyebright) or hyaluronate. Freely available. These flush pollen, dust, shampoo and dried discharge out of the conjunctival sac and help maintain a clean tear film. They do not kill bacteria and are not claimed to.
2. Tear supplements / lubricants. Carbomer gels and hypromellose drops, borrowed from human dry-eye care. Useful in brachycephalic breeds with poor blink coverage, but dose and suitability should be confirmed by your vet.
3. Medicated drops (POM-V). Chloramphenicol, fusidic acid, ciclosporin, tacrolimus, steroid combinations. These require a veterinary prescription in the UK. Using a leftover human antibiotic drop on a dog is a genuinely risky habit: if the underlying problem is a corneal ulcer, a steroid-containing drop can make it dramatically worse.
If you are still working out which category your dog’s problem falls into, our complete guide to dog eye care walks through the anatomy and the decision points.
Why your dog’s eyes are watering or discharging
Discharge is a symptom, not a diagnosis. The common UK causes, roughly in order of how often they turn up in first-opinion practice:
- Environmental irritation and seasonal allergens. Grass and tree pollen (a long UK season, roughly March to September), house dust mites, smoke, and sea or road salt. Typically bilateral, watery, itchy.
- Conformational tearing (epiphora). Shallow orbits and tight nasolacrimal ducts in Pugs, French Bulldogs, Shih Tzus, Cavaliers and Bichons mean tears spill onto the face instead of draining, producing the rust-coloured staining caused by porphyrins.
- Blocked tear ducts. Same wet face, different mechanism; diagnosed by a vet with a fluorescein passage test.
- Keratoconjunctivitis sicca (dry eye). Immune-mediated tear deficiency, over-represented in West Highland White Terriers and Cocker Spaniels. Produces thick, sticky, grey-green discharge. Confirmed with a Schirmer tear test and managed lifelong with prescription ciclosporin.
- Corneal ulceration or a foreign body. Grass seeds are the classic British summer culprit. Painful, unilateral, urgent.
- Bacterial or viral conjunctivitis. Less common as a primary problem than owners assume; usually secondary to one of the above.
Red flags: vet, not drops
Stop reading and phone your practice if you see any of these:
- Squinting, holding the eye shut, or rubbing it on the carpet
- A visibly cloudy, blue-grey or hazy cornea
- Yellow or green pus, or blood
- One pupil larger than the other
- Sudden bumping into furniture or hesitancy on stairs
- Swelling of the eyeball itself, or a bulging eye
Pain plus cloudiness is the combination that most often means an ulcer, and ulcers can perforate within 24–48 hours. Out of hours, UK owners can use their practice’s emergency provider (Vets Now, VetsNow-affiliated OOH clinics, or the RSPCA/PDSA if eligible).
A calmer daily routine starts with a gentle, sterile rinse:
Safe at-home eye support
For uncomplicated watering, dust or mild staining, a short daily routine does most of the work.
- Wash your hands and have a clean, lint-free pad ready for each eye — never reuse a pad between eyes.
- Soften the crust with a pad dampened in the rinse, held against the corner of the eye for 10–15 seconds. Do not pick dried discharge off dry skin.
- Flush, don’t dab. Tip your dog’s muzzle slightly upward and apply the rinse from just above the eye so it runs across the surface and out at the inner corner.
- Dry the folds. In brachycephalic breeds, blot the nasal fold dry afterwards — a permanently damp fold is what turns tear staining into fold dermatitis.
- Repeat once daily during pollen season, or after beach and stubble-field walks.
What to avoid: human contact-lens solution containing preservatives, tea or chamomile “washes”, diluted baby shampoo, and anything containing tylosin (an antibiotic sold in some imported tear-stain powders and not licensed for this use in the UK). For the staining side specifically, see our breakdown of tear stain removers that are actually safe.
What’s in a good eye rinse
Three things matter more than branding.
Isotonicity and pH. Canine tear film sits around pH 7.0–7.5. A rinse buffered to that range does not sting; anything acidic or hypertonic causes reflex blinking and makes the next cleaning harder.
Preservative load. Benzalkonium chloride is the usual culprit in cheap drops and is a known corneal epithelial irritant with repeated use. Preservative-free or mildly preserved formulations are preferable for daily application.
Sterility and packaging. A rinse used daily on an already-irritated eye must be sterile at fill and protected in use. Single-dose vials or a sealed dispensing tip both work; an open-mouth bottle stored in a damp bathroom does not.
The Pure Majesty Pets rinse is formulated as a mild, buffered daily cleanser rather than a medicated drop, which is exactly the category most UK owners actually need for maintenance between vet visits.
UK options compared
| Option | Prescription? | Best suited to | Limitations |
|---|---|---|---|
| Pure Majesty Pets Soothing Daily Eye Cleansing Rinse | No | Daily flushing, pollen and dust, routine discharge, staining maintenance | Cleansing support only — not a medicine for infection or ulcers |
| Sterile saline eye wash (chemist) | No | One-off flushing after a dusty walk | No buffering or soothing agents; large bottles go off once opened |
| Carbomer / hypromellose lubricant gel | Usually no, but ask | Dogs with incomplete blink or mild dryness | Blurs vision briefly; does not clean debris |
| Chloramphenicol / fusidic acid drops | Yes (POM-V) | Diagnosed bacterial conjunctivitis | Vet only; inappropriate use drives resistance |
| Ciclosporin ophthalmic ointment | Yes (POM-V) | Confirmed dry eye (KCS) | Requires Schirmer testing and lifelong use |
Where an eye rinse fits alongside the rest of your routine
Eyes rarely misbehave in isolation. Allergic dogs that water at the eyes in June are usually the same dogs licking their paws — our piece on dog eye allergies covers the overlap, and if your dog’s discharge has turned thick and sticky, read what different discharge colours mean before assuming it is “just hay fever”.
Keep a bottle in the walk bag for pollen season:
Frequently asked questions
Can I buy antibiotic eye drops for my dog over the counter in the UK?
No. Antibiotic and steroid eye preparations are POM-V and require a prescription from a UK veterinary surgeon. Over-the-counter products are cleansing rinses, washes and lubricants.
Can I use human eye drops on my dog?
Plain sterile saline is generally tolerated for a one-off flush, but medicated human drops should not be used without veterinary advice. Steroid-containing drops can seriously worsen an undiagnosed corneal ulcer.
How often should I clean my dog’s eyes?
Once daily is sensible for flat-faced breeds and during the UK pollen season. Otherwise, clean as needed after dusty, sandy or stubble-field walks.
Will an eye rinse remove tear stains?
A rinse helps by removing the porphyrin-rich tears and moisture that feed staining, and by keeping the fold clean. Existing stained hair grows out rather than bleaching away, so improvement is gradual over several weeks.
My dog is squinting after a walk in long grass. Is that urgent?
Treat it as urgent. A grass seed under the third eyelid or a corneal scratch is painful and can deteriorate quickly. Do not attempt to flush it out repeatedly at home — get it looked at the same day.
Is eyebright (euphrasia) evidence-based?
Its traditional use is long-standing, but controlled veterinary evidence is limited. Treat it as a mild soothing component rather than the reason a product works.
