If your pet is losing sight, you may do anything you can and try every product to restore their vision. Dog Glaucoma is a heartbreaking condition that not only causes vision loss but inflicts extreme pain and anxiety on those animals who have it. 

Pet parents who've heard of the many health benefits of cannabis products may wonder if CBD oil can help dogs with Glaucoma. We cover this topic and talk about the many ways that CBD can support your dog's health.

What is Glaucoma in Dogs?

Glaucoma is a condition where the aqueous humour liquid inside the eye is incorrectly circulated. A healthy eye will regulate the production and drainage of the eye fluid.

This fluid is vital because it nourishes the retina's eye tissues and protects them against foreign bodies. It also helps the eye to retain its shape by providing a healthy degree of pressure.

In Glaucoma, the eye insufficiently drains fluid, causing a build-up that creates excess pressure in the eye retina, called intraocular pressure (IOP). This pressure causes damage to the eye, specifically to the optic nerve used to transport visual information to our brain. 

What Causes Dog Glaucoma?

Glaucoma conditions are either primary or secondary. Let's explain:

Primary Glaucoma is brought on by genetics and takes place gradually. For some pets, Glaucoma is an inherited condition. It is common in certain dog breeds, such as: 

Secondary Glaucoma is caused by a sudden blockage of eye fluid and the consequent build-up. This unexpected drainage problem could be caused by previously undiagnosed eye disease or trauma. Chronic retinal detachment, advanced cataracts, eye tumors, and infections are all triggers for secondary Glaucoma.

Symptoms of Glaucoma in Dogs

The chronic build-up of pressure in the eye is extremely painful for people and canines. Your dog is unable to come and tell you about the beginnings of pain, and so, in most cases, Glaucoma is only noticed by pet parents after vision loss has begun. 

Besides eye pain, these are the most common symptoms of Glaucoma in dogs:

  • Sensitivity to touch around the eyes and head

  • Behavioral changes, such as depression and aggression 

  • Disinterest in daily activity

  • A loss of appetite

  • Panting

  • Change in sleeping habits

  • Headaches are displayed by head-bumping walls, furniture, etc. 

You may eventually begin to see changes in the eyes themselves. Enlarged pupils that are non-responsive to light, eyeball enlargement, red blood vessels, and a cloudy eye lens are progressed symptoms of Glaucoma.

Glaucoma Treatments for Dogs 

If you notice any changes in your dog's eyes, it is best to get them checked out by your dog's veterinarian. The longer intraocular pressure builds, the more damage occurs to the eye. Your veterinarian will use a tonometer to measure eye pressure.

It's a painless procedure where the veterinarian will use a local anesthetic eye drop to numb the canine eyeball. The reading will reveal the amount of pressure in the eye, and whether it is above the healthy range. 

Early diagnosis will allow your veterinarian to treat Glaucoma by using methods that slow down the progression of the condition. Your vet may prescribe medication or eye drops to dry out or restrict the production of eye fluid.

Surgical treatment is also an option for decreasing eye pressure. Sadly, there is no cure for canine Glaucoma, and a large percentage of dogs diagnosed with the disease will be living in the dark within a year of their diagnosis. 

Even though the optic nerve damage cannot be reversed, the veterinarian can perform procedures to reduce the eye pressure and ease the pain. Cyclocrotherapy is a cosmetic procedure that destroys cells that produce aqueous humour. Many times though, the blind eye will be removed so that pain management (and its cost) can discontinue. 

Without the hope of a cure, the main focus of treatment is to reduce pain symptoms and help your dog to remain comfortable. Many dogs can still live a happy life without their sight in one or both eyes. 

CBD Oil for Dogs with Glaucoma 

Whether in humans, rats, or dogs, CBD oil for Glaucoma is a little complicated, and studies have found conflicting results. 

  • A 2006 study on the effects of CBD sublingual administration on intraocular pressure (IOP) found that THC (tetrahydrocannabinol) reduced eye pressure temporarily, while CBD did not affect the IOP. High doses of CBD increased the IOP slightly. 

  • A 1984 study looked at other cannabis plant compounds, mainly Cannabigerol (CBG) and Cannabinol (CBN). When given chronically, they lowered ocular tension considerably.

  • The United Kingdom Journal of Ophthalmology found that "Cannabinoids effectively lower the intraocular pressure (IOP) and have neuroprotective actions." They go on to state that cannabinoids can be effective in treating Glaucoma.

  • Several studies mention Glaucoma in their list of diseases that the therapeutic potential of cannabinoids can treat. 

  • Experts from the Center for Biomolecular Science and the Department of Psychological and Brain Sciences found that "CBD may interfere with those IOP-lowering effects of THC."

  • A 2003 study stated that "Cannabinoids (CBD and THC) have been demonstrated to protect neuron cultures from glutamate-induced death," which means that these cannabinoids can slow down or prevent cell death of the retinal. 

With these contradictory results, we see that CBD is no miracle cure. Glaucoma is unrecoverable. However, CBD has been shown to effectively reduce cell death, discomfort, and anxiety that accompanies many diseases, Glaucoma included. 

Benefits of CBD for Dogs with Glaucoma

Good quality, full-spectrum CBD hemp oil that is rich in cannabinoids and even a tiny 0.3 percentage of THC can help your pet's condition and overall wellness in the following ways:

  • CBD can support cellular health. This may benefit the eyes. 

  • Antioxidants can improve eye health, and CBD may support antioxidant function.

  • CBD supports the body's immune response.

  • CBD helps maintain a normal inflammatory response in the body.

  • CBD can help with occasional discomfort.

  • CBD may help protect body cells and tissues.

  • If your blind or vision-impaired dog is exhibiting nervousness, discontentment, or responding to environmentally-induced stress, CBD can help keep your pet calm and relaxed.

  • CBD supports normal brain and nerve function.

  • And more

Are there Any Risks? 

Pet owners increase the risks of using CBD when they carelessly buy CBD products without making sure it's the best quality. CBD that is hemp-derived, organic, and extracted using CO2 is safe for dogs and cats.

Few pets have experienced the side effects of dry mouth, diarrhea, and low blood pressure. Monitor your pet when you first introduce CBD to their life. Lower the dosage if any of these side effects manifest. 

Using CBD Oil for Dogs in a Glaucoma Treatment Plan

Always speak to your veterinarian before adding CBD supplements or natural holistic options to your dog's diet. Your vet may have their reasons for being skeptical of CBD, knowing that it cannot cure them of their condition. Be clear that you would like to try CBD oil for its ability to support your dog's stress levels, sleeplessness, or discomfort.

How to Use CBD Oil for Dogs

You've found the best CBD oil for your dog and added it to your cart. Make sure it's high quality, full-spectrum, and hemp-derived. Once you've proceeded through checkout and received your parcel, we'd like to help you with the next step.

Some fussy dogs may be skeptical of the dropper in their mouth. A slow introduction is important to introduce CBD to their wellness care successfully.

CBD Oil Dosage Calculator

This first thing you'll wonder after unwrapping your new CBD pet oil will be, "How much CBD do I give my pet?"

A general CBD dosage guideline falls within the range of 1-5 mg of CBD per 10lbs of body weight. 

Your small 25-lb Welsh Corgi can receive anything from 2 - 10mg of CBD daily. However, a hefty 100-lb Burmese Mountain dog can receive anything from  10 - 50 mg of CBD daily. 

Hemp pet brands should provide information and dosing guidelines with their product. Our Honest Paws CBD oils are available in various potency strengths. Dosing guidelines are as follows:

  • Our 125 mg strength bottle of CBD oil (for small dogs under 25lbs) contains 4 mg of CBD oil in a full 1 mL dropper. 

  • Our 250 mg strength bottle of CBD oil (for medium dogs around 25-50lbs) contains 8 mg of CBD oil in a full 1 mL dropper. 

  • Our 500 mg strength bottle of CBD oil (for large dogs over 50lbs) contains 16 mg of CBD oil in a full 1 mL dropper. 

  • Our 10000 mg strength bottle of CBD oil (for extra strength) contains 33 mg of CBD oil in a full 1 mL dropper. 

Depending on your pet's condition or level of discomfort, some pet parents may opt for a more potent dose. For the best response, we suggest starting with the lowest dose and gradually increasing it.

How to Administer CBD Pet Oil

There are a few different methods for giving your dog CBD oil. Find the technique that works best for your pup.

  • Direct oral application. This is done by drawing the oil into the dropper, opening your dog's mouth, and releasing the liquid under the tongue or far back in the mouth. This method will have the quickest result (20-60 minutes) as the CBD is absorbed directly into their blood.

  • Add it to their meal. Giving your dog CBD at mealtime is a great way to add it to their routine. Storing the bottle close to their food will also remind you to give it to them. 

  • Use dog treats. Soak a few drops of CBD oil onto a porous treat, and your doggo will gulp it down before they even realize that it tastes slightly different. Very sneaky!

  • Make DIY dog treats. Be careful when baking CBD treats as a high temperature (above 356 degrees Fahrenheit) can destroy the CBD bioavailability. Rather, try your hand at some no-bake CBD balls that include their favorite flavors like peanut butter, banana, or even berries. Or spoil them with frozen CBD-spiked lollies during summertime. 

  • Buy them CBD edibles. If you don't want to risk pouring CBD oil into a mixing bowl, opt for store-bought CBD dog treats containing the perfect 5 mg per CBD bite or chew

Treating Glaucoma Symptoms with CBD Oil for Dogs

You cannot give your dog their sight back. But that doesn't mean you cannot bond with your pup, play hunting games that offer mental stimulations, and take them for walks. There are many ways that you can help your partially blind or blind pet.

Playing with noisy toys, clearing obstacles around the home, talking to them often, buying them a halo, and using textured rugs and fountain-style water bowls are just some of the many ways that you can make your home a safe space for your vision-impaired pet. 

By offering your pet CBD oil, you'll be supporting their health, promoting calm and relaxation, and helping with occasional discomfort. It's a great way to support your dog's cardiovascular, immune, and neurological functions. 

A dog with loss of vision in one eye or limited vision can still be content and happy with an owner who takes care of them. Your best friend needs you, even if they cannot see you.
