Ether MS is a respiratory anesthetic. Do you want your dog to stop barking and stun it, or do you want to stun it before surgery? The use of narcotic drugs should be operated by professionals, and the dosage should be calculated according to the weight. Always pay attention to the changes of the dog's heartbeat, breathing and pupil after anesthesia. If anesthesia allergy occurs, cardiotonic and resuscitation measures should be implemented immediately. Otherwise your life will be in danger!
