FAQs
Is Xanax safe for dogs?
Under veterinary supervision, yes — alprazolam can be used safely in dogs for short-term or situational anxiety management. Without vet supervision, it carries serious risks including excessive sedation, respiratory depression, and unpredictable paradoxical reactions. Never use human prescriptions for your dog.
Are there better alternatives to Xanax for dog anxiety?
Many vets prefer trazodone, gabapentin, or Sileo (dexmedetomidine) for situational anxiety, and fluoxetine or clomipramine for chronic anxiety disorders. These are often better tolerated with fewer side effects. Behaviour modification alongside medication gives the best long-term outcomes.
