Xanax (alprazolam) is sometimes prescribed by veterinarians to help dogs manage anxiety, fear, or stress-related behaviors, such as during thunderstorms or travel. While it can be effective in calming anxious dogs, it should only be used under veterinary supervision, as incorrect dosing can cause drowsiness, loss of coordination, or even aggression. Long-term or unsupervised use may lead to dependence or withdrawal symptoms. Not all dogs respond well to Xanax, and it can interact with other medications. Pet owners should never give human Xanax to dogs without a vet’s guidance and should discuss safer or natural alternatives for anxiety management.
