The American Animal Hospital Association recommends that veterinarians routinely administer appropriate analgesics to minimize pain in their patients.
Analgesics need to be used preemptively for any medical condition or veterinary procedure associated with pain and for as long as necessary to prevent pain during recovery. AAHA agrees with The American College of Veterinary Anesthesiologists that if a procedure is painful to humans it will be painful to animals.
