Mental Health supports for veterinarians
This may be a time of increased stress and anxiety for veterinarians as they discuss and prepare for HPAI with their clients.
The Canadian Veterinary Medical Association's incoming Director of Wellness, Dr. Kathy Keil, has offered the following resources for those who feel that they may be beneficial to them:
The CVMA website outlines supports available to Canadian veterinarians:
https://www.canadianveterinarians.net/veterinary-resources/veterinary-health-and-wellness-resources/mental-health-awareness-resources/who-ya-gonna-call/
CVMA also offers an anonymous and confidential peer-to-peer online community for all Canadian veterinarians and student veterinarians through Togetherall. ABVTA now offers this online service for AB RVTs too. This community is an opportunity for veterinarians to reach out to their peers to share a situation or an issue where they need a peer to listen, offer support and guidance. The community has 24/7/365 oversight with a licensed mental health professional for additional safety.
