How does CBD For Dog Glaucoma Work?


CBD for dog glaucoma works on three levels, it can decrease intraocular pressure (IOP), helps alleviate pain, and reduces inflammation. CBD does this by interacting with the endocannabinoid system (ECS). 

The ECS is responsible for maintaining a state of health and balance. It consists of endocannabinoids, cannabinoid receptors, and enzymes. CBD replaces the endocannabinoids, binds with their receptors, and supports the endocannabinoid system. 

It should be noted that CBD is not FDA-approved for use in veterinary medicine. However, it is established that the supplement is safe and beneficial, not just for glaucoma but also for epilepsy management, joint pain relief, etc. Just make sure you talk to your vet before using pet CBD products. 

Does CBD Help With Glaucoma in Dogs?

Yes, CBD can help dogs with glaucoma. CBD (Cannabidiol) is a natural extract derived from the Cannabis sativa plant (particularly the hemp plant). 

However, the use of CBD for dog glaucoma is a controversial topic mainly because of two reasons. First, research shows some contradictory results. Some studies show CBD as a promising tool for managing glaucoma, others have found that CBD does not affect the IOP. Second, most results and statistics about the effects of CBD on glaucoma are derived from human studies. 

However, considering that the contradictory results occur when CBD is used in significantly high amounts, the mainstream opinion is that CBD does more good than bad for glaucoma patients. Plus, the ECS systems work the same in all mammals, and we can assume that CBD will affect dogs the same way it affects humans with glaucoma.

How to Use CBD for Dog Glaucoma

There are many CBD products available on the market. The effects are the same; the only thing that matters is to double-check and make sure you are using a pet-specific product. CBD products made for humans are potentially toxic to dogs. 

With that being covered, you can choose between CBD oils and CBD treats. The oils are more fast-acting and cost-effective but harder to administer. In contrast, the treats need more time to kick in and are more expensive but easy to use because of the dog-friendly flavors. 

Finally, do not forget to consult with your vet before adding cannabis to your dog’s glaucoma treatment plan. This is because CBD can interact with certain prescription medications.

CBD Dosage For Dogs With Glaucoma

The use of CBD oil for glaucoma does not come with specific CBD dosage guidelines. The general recommendation is to give your dog between 1 and 5 mg of CBD per 10 pounds of body weight per day. However, finding the right CBD amount will take some experimentation. 

We also advise you to start with the lowest dose for your dog’s body weight and then gradually increase the CBD amount. 

Sudden CBD implementation can cause minor and transient side effects such as dry mouth, increased thirst, low blood pressure, lethargy, drowsiness, and diarrhea. They can also occur if you miscalculated the CBD dosage and gave your dog too much. However, do not panic – dogs cannot overdose on CBD oil. 

What are the Benefits of CBD for Dog Glaucoma?


CBD for dog glaucoma helps on several levels. Let’s dive into the scientific evidence backing up the use of CBD for dogs with glaucoma. 

CBD may Effectively Lower Intraocular Pressure. According to a study published in The United Kingdom Journal of Ophthalmology, “cannabinoids effectively lower the intraocular pressure (IOP) and have neuroprotective actions.” Another study found that chronic use of cannabigerol (CBG) and cannabinol (CBN) leads to a significant reduction in IOP.

CBD’s Neuroprotective Features may Inhibit Glutamate Effects, Slowing Down Glaucoma Progression. A groundbreaking study determined that the CBDs’ anti-glaucoma powers stem from their neuroprotective features. Namely, CBD inhibits the effects of glutamate – a neurotransmitter that causes neurotoxicity and eye cell death, thus contributing to glaucoma development.

CBD’s Antioxidant and Anti-Inflammation Properties can Protect Cellular Health. It is a well-studied and confirmed fact that CBD has strong antioxidant and anti-inflammation properties. These features support overall cellular health by preventing oxidative and inflammatory cell damage.

CBD Can Relieve Discomfort and Pain. CBD has potent anti-pain characteristics, and many studies confirm its effectiveness in treating chronic pain. CBD can reduce pain perception by increasing the levels of anandamide in the body – a compound associated with pain regulation.

What can I Give My Dog for Glaucoma?

Basically, there are two mainstream treatment approaches for glaucoma:

  • Topical medications. The medications for decreasing the intraocular eye pressure belong to the group of topical carbonic anhydrase inhibitors (such as dorzolamide, brinzolamide, and methazolamide). They need to be applied twice or even three times per day.  
  • Surgery. There are different surgical options, but enucleation (removing the eyeball) is the most commonly practiced. The approach is radical, but it is the only option for dogs with advanced glaucoma stages and hard-to-manage pain. 

The use of CBD for dog glaucoma is a relatively novel concept. However, it should be emphasized that CBD is not a cure for glaucoma and it can only be used as part of the treatment, combined with other approaches. 

How CBD Compares to Alternative Dog Glaucoma Treatments

Canine glaucoma is a progressive and irreversible condition that can only be managed. Sadly, most mainstream glaucoma treatments fail within months of the diagnosis. Surgical approaches are more efficient but are also more invasive and radical. 

On the other hand, CBD for dog glaucoma is a 100% natural alternative addition for glaucoma management. CBD is safe for dogs and based on studies, it has promising effects on pets with glaucoma. Plus, supplementing with CBD for dog glaucoma is more straightforward than putting eye drops in the affected eye several times per day. 

Dog Glaucoma: Signs & Symptoms


Canine glaucoma is a common eye condition that manifests with increased intraocular pressure (IOP). Normally, the dog’s eyes produce aqueous humor fluid, which nourishes the eye tissues, retains the eyeball’s shape, and supports overall eye health.  

In glaucoma, the drainage is impaired, leading to fluid buildup – increased eye pressure or chronic ocular hypertension (45-64 mmHg). Over time, the pressure damages the eye and optic nerve. If left untreated, glaucoma can lead to retinal detachment. The detachment of the retina is soon followed by loss of vision. 

Causes of Glaucoma in Dogs

There are two types of glaucoma in dogs, and each is linked with different causes. Here is a short explanation of the glaucoma causes based on type:

  • Primary glaucoma – is an inherited condition common in certain dog breeds like Poodles, Cocker Spaniels, Chow chows, Siberian Huskies, Beagles, Basset Hounds, and Labrador Retrievers. 
  • Secondary glaucoma – occurs due to unexpected drainage issues in dogs due to eye trauma and diseases like cataracts, eye tumors, and infections.

Signs Your Dog has Glaucoma and What to do

Glaucoma is an excruciating eye disease. However, dogs are usually good at covering the red flags for pain. Therefore, most glaucoma cases are diagnosed once blindness sets in and the condition is already advanced.

Here are some common symptoms of glaucoma in dogs:

  • Eye pain and frequent headaches 
  • Touch sensitivity around the eyes and head
  • Appetite loss, panting, and lethargy
  • Behavioral changes – aggression or depression
  • Changes in the sleeping habits 
  • Disorientation and bumping into objects 
  • Clouding of the lens 
  • Eyeball enlargement and cornea redness 
  • Increased and light unresponsive pupils

If your dog shows one or more of these signs and symptoms, you need to call your trusted veterinarian and schedule an appointment. The sooner you get to the bottom of the problem, the better the outcome.
