Small and toy breed dogs face a unique set of ocular health challenges. Many small breeds — including Shih Tzus, Chihuahuas, Poodles, Maltese, and Cavalier King Charles Spaniels — are genetically predisposed to early-onset cataracts, dry eye, and other forms of oxidative ocular damage. Their smaller eyes are proportionally exposed to the same amount of UV radiation and metabolic oxidative stress as larger breeds, with less tissue mass to buffer that damage over time. Proactive antioxidant support can make a meaningful difference in how well those eyes hold up through a long life.
Ocu-GLO Vision Support Gelcaps for Small Dogs are sized specifically for dogs weighing 10 lbs and under. Developed by board-certified veterinary ophthalmologists and supplement researchers, the formula was built on research from the AREDS (Age-Related Eye Disease Studies) — the same landmark research that shaped human eye supplement standards — and adapted to the specific physiological needs of the canine eye. The small dog gelcap delivers the full 12-antioxidant Ocu-GLO formula in a dose calibrated for lighter body weights.
At the heart of the formula is the proprietary GLO blend: FloraGLO® Lutein, Grape Seed Extract, and Omega-3 fatty acids (EPA and DHA). FloraGLO® is the pharmaceutical-grade lutein used in peer-reviewed human clinical trials — not a commodity ingredient — and it accumulates directly in the retina and lens, where it provides continuous protection against free radical-induced cell damage. Grape Seed Extract contributes proanthocyanidins that neutralize reactive oxygen species in the lens epithelium. EPA and DHA support the structural integrity of photoreceptor membranes and retinal circulation.
Nine additional antioxidants — including Vitamin C, Vitamin E, Alpha Lipoic Acid, Coenzyme Q10, Green Tea Extract (EGCG), Astaxanthin, Rutin, Zinc, and a complete B-vitamin complex — work in concert with the GLO core to provide layered protection across multiple cellular pathways. This multi-pathway approach ensures that when one antioxidant is consumed neutralizing a free radical, others are available to regenerate it and continue the protective cycle.
Each gelcap is designed to be swallowed whole at mealtime. At 90 capsules, this bottle provides a 3-month supply for the smallest dogs (under 10 lbs, 1 capsule daily). NASC quality-seal certified, made in the USA, and soy-free.
Key Ingredients
-
GLO Proprietary Blend (FloraGLO® Lutein, Grape Seed Extract, Omega-3 EPA/DHA) — three clinically researched antioxidants targeting the retina, lens, and cornea
-
Vitamin C — water-soluble free radical scavenger; supports collagen in the cornea and sclera
-
Vitamin E — fat-soluble antioxidant protecting the lipid-rich membranes of photoreceptor cells
-
Alpha Lipoic Acid — both water- and fat-soluble; uniquely able to recycle other antioxidants within the cellular antioxidant network
-
Coenzyme Q10 — powers mitochondria in high-energy ocular tissues; declines with age
-
Green Tea Extract (EGCG) — plant polyphenol with broad anti-inflammatory and antioxidant properties
-
Astaxanthin — penetrates the blood-retinal barrier; one of the most potent antioxidants for retinal protection
-
Rutin — supports ocular vascular integrity and reduces capillary fragility
-
Zinc — essential co-factor for retinal antioxidant enzymes; deficiency accelerates retinal degeneration
-
B-Vitamin Complex (B1, B3, B5, B6, B7, B9, B12) — supports optic nerve function and energy metabolism in visual tissues

Supplement Advisor's Note
The small dog gelcap is often overlooked in favour of the powder blend for tiny dogs, but for dogs that swallow capsules easily it offers a practical advantage: no measuring, no mixing, no smell in the food bowl. The gelcap format also provides a slightly different omega-3 delivery profile (liquid-filled) compared to the powder blend. For toy and small breeds with known breed-related ocular risks — particularly Miniature Poodles (progressive retinal atrophy), Cocker Spaniels (cataracts), and Shih Tzus (corneal ulcers and dry eye) — starting Ocu-GLO at one to two years of age rather than waiting for signs of disease is the approach most aligned with current veterinary ophthalmology thinking.
Frequently Asked Questions
What makes this different from the medium/large dog gelcap?
The small dog gelcap is a lower-dose formulation calibrated for dogs 10 lbs and under. The medium/large dog gelcap delivers a higher dose appropriate for dogs 11 lbs and above. Using the wrong size means either under-dosing (using the small in a large dog) or unnecessary over-supplementation (using the large in a very small dog). Always match the product to your dog's actual weight.
My dog is 12 lbs — which size should I use?
For dogs over 10 lbs, use the Ocu-GLO Gelcaps for Medium & Large Dogs. At 11–30 lbs, the dose is 1 medium/large gelcap daily. The small dog formula is intended for dogs 10 lbs and under only.
Can I use this if my dog already has cataracts?
Yes — Ocu-GLO is commonly used in dogs diagnosed with cataracts or other oxidative eye conditions, as a complement to veterinary treatment. Many veterinary ophthalmologists recommend it alongside conventional therapy to slow progression and protect remaining healthy tissue. It is not a cure, but it supports the eye's own antioxidant defences.
How long does the 90-capsule bottle last?
For a dog under 10 lbs receiving 1 capsule daily, the bottle provides a 90-day (3-month) supply. This makes the 90-count bottle the most cost-effective option for daily long-term supplementation.
Is Ocu-GLO safe for long-term daily use?
Yes — the formula has been used in clinical and companion animal settings for over 15 years and is designed for continuous daily use throughout the pet's life. It is also certified safe for perioperative use, meaning it does not need to be stopped before veterinary procedures.
