L-theanine, the amino acid naturally present in tea leaves, proves to be beneficial not just for humans but also for dogs. Many dog owners and veterinarians have delved into the realm of L-theanine supplements to aid in soothing anxious or stressed dogs. Its application extends to scenarios such as thunderstorms, fireworks, separation anxiety, or vet visits. L-theanine's calming influence provides dogs with relaxation without inducing drowsiness or sedation, presenting a natural avenue for managing canine anxiety. Nonetheless, as with any supplement, consulting with a veterinarian is indispensable to determine the suitable dosage and usage for your specific dog.
