Xanax for dogs is sometimes prescribed by veterinarians to help manage anxiety, stress, or fear-related behaviors such as separation anxiety, loud noises, or travel stress. Xanax (generic name alprazolam) belongs to the benzodiazepine class of medications, which work by calming the nervous system. While it can be effective for short-term anxiety relief, it should only be given under a veterinarian’s supervision, as incorrect dosing can lead to side effects such as drowsiness, confusion, or even aggression in some dogs. The dosage depends on the dog’s weight, age, and overall health.
