Green Nile was established in 2019 with the goal of helping guide pet owners on how to utilize medical cannabis for pets in the safest and most effective way possible. As cannabis has become legal in many states, many pet owners are looking to find ways of incorporating cannabis into their pet’s medical protocols either as an adjunct to pharmaceuticals or in lieu of conventional modalities. A 2020 publication concluded that human patients and dog owners reported similar motivations for using cannabis products to treat chronic pain, with the more popular reasons being that cannabis products are natural, are preferred over conventional medication, and are believed to be a good treatment option for pain.

With our years of experience, including hundreds of patients treated with cannabis, we are dedicated to providing a supportive, educational cannabis consultation that will arm pet parents with the tools they need to make an informed decision for their beloved pet.

We are truly honored to be part of your pets team.

Veterinary Cannabis Society 501(c)(3) non-profit organization-President and Co-founder

Dr. Lindsey Wendt


Dr. Lindsey Wendt was born and raised in Southern California. After graduating with honors from the UC Davis School of Veterinary Medicine in 2012 she completed an intensive small animal rotating internship at VCA West Los Angeles Animal Hospital.

Dr. Wendt spent many years working general practice and emergency in the greater Los Angeles area which allowed her to practice medicine in various communities. Her own beloved dog Nala developed a chronic gastrointestinal disease that led to her exploration of alternative modalities and holistic therapies to better manage her condition, and to calibrate her focus on healing rather than just managing her symptoms from a conventional medicine approach. Working in the non-profit sector for several years allowed Dr. Wendt to witness the response to the incorporation of many of these integrative approaches into the general care of this special population of animals, and inspired her to create a mobile integrative medicine practice to service the pet population of the Los Angeles area.

Dr. Wendt started to explore the use of cannabis in veterinary medicine specifically as an alternative to treat Nala’s arthritis since she had concern for the negative contribution that conventional arthritis management had on her compromised health condition. She became increasingly intrigued by the diverse application that cannabis medicine has in our pets, and began to explore how she could bring this under-recognized sector of medicine to her beloved patients. Dr. Wendt has gained certifications in Acupuncture and Chinese Food Therapy through the Chi University in Florida, and is pending certification as a Canine Rehabilitation Therapist through the Canine Rehabilitation Institute.

Her current practice, Crystal Lotus Veterinary Care, has a strong focus on the incorporation of medicinal herbs, adaptogens, mushrooms, cannabis and other nutritional supplementation as she has found it to be a necessary and often overlooked component of health management of our fur companions. She believes that high quality supplements are not only important for the treatment and management of illness, but also maintaining general health and disease prevention.
