Introduction:

marijuana (CannabissativaL.) is a plant native to Asia that is increasingly recognized for its therapeutic value in human and veterinary medicine. It contains a large number of components among which the phytocannabinoids stand out, of which the most representative are delta-9-tetrahydrocannabinol (THC) and Cannabidiol (CBD) that are coupled respectively to the CB1 and CB2 receptors in the endocannabinoid system, which is a neurotransmitter system between cells that regulates various processes in vertebrates such as memory, pain, inflammation, appetite and immune processes among others.

Aim:

to carry out a narrative synthesis of the endocannabinoid and cannabidiol system in the management of pain in dogs, from the search of publications in electronic databases PubMed, NCBI, SciELO, Science Direct, Dialnet, Google and Google Scholar.

Results:

CBD is the main cannabinoid used in pain management therapy in dogs due to its analgesic proper-ties and lack of psychoactive effects.

Conclusion:

there is evidence of the need for more research with controlled clinical trials on the therapeutic use of cannabidiol, which have internal and external validity, with more significant populations in the species of interest.
