We cannot give advice or recommendations for individuals (including animals), however we can provide resources. You may find that a good book on herbalism and pet care would be helpful. Herbs for Pets and Dr. Pitcarin's Complete Guide to Natural Health for Dogs and Cats are both good resources.
We have a couple of posts on our blog that may be useful to you as well:
You might also be interested in The Herbs for Animals Intensive. It is a two session series—one video lesson and one written lesson with a short accompanying video— that will help you gain a better understanding of how to safely use herbs and flower essences to support the well-being of pets and other animals.
This intensive is only available to as part of The Herbarium membership – our robust online reference source for herbalists of all experience levels! The Herbarium annual membership includes an ever-expanding library of plant monographs, intensives, articles, podcasts, videos, tutorials, and charts, all based on carefully gathered research and the wisdom of many contributing herbalists.
