Cannabidiol (CBD), a non-psychoactive compound found in cannabis, has garnered attention for its potential health benefits in humans and pets alike. A recent study, titled “Long-term effect of oral cannabidiol administration to healthy adult dogs on tear production, intraocular pressure, and tear concentrations”, explores the impact of sustained CBD use on the ocular parameters of healthy dogs.

Study Overview

The study involved a controlled trial where a group of healthy adult dogs were administered oral cannabidiol daily for a prolonged period. Researchers aimed to determine if there were any significant changes in the dogs’ tear production, intraocular pressure (IOP), and tear film CBD concentrations.

Key Findings

The research indicates that long-term oral administration of CBD does not adversely affect the tear production and IOP in healthy dogs. This finding is particularly noteworthy for pet owners and veterinary professionals considering CBD for long-term use, as it suggests that it may not pose significant risks to canine eye health, at least in terms of the parameters measured. Furthermore, CBD was detected in the tear film of these dogs, opening up avenues for future research on its localized ocular effects.

Importance for Veterinary Care

This study holds considerable importance in the realm of veterinary medicine. As CBD products continue to rise in popularity for pet care, particularly for conditions like anxiety, pain, and inflammation, understanding their long-term impact is crucial. The evidence pointing to the benign nature of CBD on ocular health may provide reassurance to pet owners considering it as a supplement for their dogs.

Implications for Future Research

The presence of CBD in the tear film underscores the need for further investigation into how CBD might affect ocular tissues when administered systemically. This opens up possibilities for CBD’s therapeutic use in addressing ophthalmic conditions in dogs. The study paves the way for future in-depth analysis that could ultimately enhance canine eye care and widen the scope of treatments available to our four-legged friends.


While the study’s results are promising, pet owners are encouraged to consult with veterinary professionals before beginning any CBD regimen with their pets. As research continues to evolve, it is vital to base decisions on scientific evidence tailored to individual pet needs.
