Xanax is alprazolam, a prescription benzodiazepine that veterinarians sometimes use for anxiety, panic, noise phobia, or fear-related problems in dogs.

Do not give your dog your Xanax unless a veterinarian has prescribed alprazolam for that dog and provided exact instructions. The appropriate medication and dose depend on your dog's size, age, health conditions, anxiety trigger, and other medications.

Why Xanax Can Be Risky for Dogs
Alprazolam is a benzodiazepine sedative. In dogs, it may cause sleepiness and poor coordination. Some dogs have the opposite reaction, including anxiety, excitement, agitation, or aggression. Long-term use can lead to physical dependence.
Alprazolam may be unsuitable for dogs with liver or kidney disease, glaucoma, pregnancy, advanced age, debilitation, or a history of unusual reactions to sedatives. A veterinarian may also need to check for interactions with other medicines, including central nervous system depressants, phenobarbital, fluoxetine, fluvoxamine, some antifungal drugs, and tricyclic antidepressants.
A human tablet strength is not automatically appropriate for a dog. Do not split a tablet, repeat a dose, or calculate a dose from the human label or an online dosing chart.
When a Veterinarian Might Prescribe Alprazolam
A veterinarian may consider alprazolam when a dog has a specific, predictable trigger such as thunderstorms, fireworks, travel, or a veterinary visit. Veterinary behavior guidance distinguishes short-term medication for an occasional trigger from longer-term treatment for ongoing anxiety or separation distress.
Medication is only one part of an anxiety treatment plan. Depending on the cause, your veterinarian may recommend behavior modification, environmental changes, or a different prescription medicine.
What If Your Dog Already Took Xanax?
If your dog took an unprescribed Xanax tablet, took more than prescribed, or you do not know how much it swallowed, call your veterinarian, an emergency veterinary hospital, or animal poison control immediately.
Have the medication bottle ready. The veterinary professional will need the tablet strength and the possible amount missing. Also note your dog's weight, age, current symptoms, and the approximate time of ingestion.
Do not induce vomiting or give home remedies unless a veterinary professional tells you to do so.
Possible poisoning signs include marked sleepiness, weakness, loss of coordination, agitation, vomiting, other gastrointestinal signs, and, in severe cases, slowed breathing or cardiovascular depression. A dog that is unconscious, having trouble breathing, having seizures, or unable to stand needs immediate emergency care.
Your dog should be assessed even if it appears normal. The risk depends on the amount swallowed, your dog's health, and any other substances or medications involved.
What You Can Do for Anxiety Right Now
Until you speak with a veterinarian, reduce the trigger instead of trying to sedate your dog yourself. Move your dog to a quiet, secure room. Close the curtains during fireworks or storms, use gentle background noise, and avoid punishment or forced exposure.
For recurring anxiety, arrange a veterinary appointment. The veterinarian can look for an underlying cause and recommend the safest combination of medication, environmental changes, and behavior support.
