Xanax for dogs is sometimes prescribed by veterinarians to help manage anxiety-related conditions such as noise phobias, separation anxiety, or situational stress. It works by calming the nervous system, but it is not suitable for every dog. Because Xanax is a prescription medication for humans, its use in pets should only occur under strict veterinary guidance. Possible side effects include drowsiness, changes in behavior, or coordination problems. Xanax is usually part of a broader anxiety management plan that may include training, environmental changes, or other treatments. Pet owners should never give dogs medication without professional approval.
