Benzodiazepines (Valium, Xanax, Etc.)
Benzodiazepines are generally considered safe, but may be avoided in dogs with certain underlying health conditions. Additionally, in some dogs, they may cause excitement rather than calmness.
Is it safe to tranquilize a dog?
Medications used to tranquilize animals can produce unintended side effects. However, airlines and professional pet transport companies forbid any form of sedation because it increases health and safety risks for dogs and cats. Sedated animals lose muscle control and cannot maintain their balance.
