Testimonials - Patients I have helped through Psychopharmacology
Lucy Daniels, BSc (Hons), Daniels Dogs
As a Clinical Animal Behaviourist, there are times when collaboration with a Veterinary Behaviourist is essential to provide the best possible care for a case. I had the pleasure of consulting with Dr. Jahn on a particularly challenging case involving a young dog who was very anxious and traumatised. The dog required psychopharmacological support alongside a carefully tailored behaviour modification plan to address his fear and anxiety effectively. Dr. Jahn's expertise and guidance were absolutely invaluable. Her approach was not only thorough but also exceptionally prompt, both during the initial consultation and in her follow-up support. Thanks to her knowledge, we were able to help this dog much more effectively. I greatly appreciated Dr. Jahn's collaborative and compassionate approach, and I very much hope to work with her again in the future.
Eileen Butler with Mutley
Finding out about Dr Katrin and her team has been the best thing that has happened for me and my canine companion! Mutley was very anxious and was developing aggressive traits towards some people. I was at my wit's end, upset and very worried about my beautiful boy. From many honest and open conversations and observations, Dr Katrin was able unpack his body language (and mine!) and guide me towards understanding his body language and triggers. She shared strategies for me to deal with any potential triggers and stress points and we added a medication regime to help reduce his anxiety. As a result of this, and with much patience and time, Mutley is becoming a more confident, happy and calm boy. The results so far have been amazing, and I know that I can always reach out to Dr. Katrin for advice and support.
Rona with Millie
Dr. Katrin gave a voice to my anxious, other-cat-hating, litter-box-avoiding cat and helped me to see, understand and change. I was in a state of despair before meeting Dr. Katrin and now I have an ally, who is incredibly generous with her time and attention, and who equips me – on many levels – to manage and handle what was once a very problematic pet!

Just finished lesson 3 in module 1. I am blown away by the content and organisation of the material, including downloads. I will be spreading the word to anyone who is interested in a great psychopharm course.
Natasha with Spokie & Leila
Spokie (it means little ghost in Afrikaans) was a feral cat which I rescued from a basement parking garage. She was very aggressive and soon I realized that I was out of my depth with how to handle her. I would many times wonder if I made the right decision. I was referred to Dr Katrin and told that she would be able to evaluate Spokie and give some advice. It was life changing!! With Dr Katrin’s guidance, I started understanding Spokie’s cues of when to touch and when not to. I read her body language and now understand when she is in a good mood or when I should rather leave her alone. Dr Katrin made suggestions on how to rearrange the room so that Spokie could get to places where she could calm down and hide if she needed to. She’s receiving medication which is managing her extreme anxiety and I am even able to touch her, she sits on my lap and she loves playing, something I never thought I would see.
