Acepromazine
There is one drug commonly used in anesthetic
protocols that should not be used in the Boxer The
drug is Acepromazine, a tranquilizer, which is often
used as a preanesthetic agent. In the Boxer, it tends
to cause a problem called first degree heart block, a
potentially serious arrhythmia of the heart. It also
causes a profound hypotension (severe lowering of
the blood pressure) in many Boxers that receive the
drug. Recently, on the Veterinary Information
Network, a computer network for practicing
veterinarians, an announcement was placed in the
cardiology section entitled "Acepromazine and
Boxers" This described several adverse reactions to
the drug in a very short time span at a veterinary
teaching hospital. All the adverse reactions were in
Boxers. The reactions included collapse, respiratory
arrest, and profound bradycardia (slow heart rate,
less than 60 beats per minute). The announcement
suggested that Acepromazine should not be used in
dogs of the Boxer breed because of a breed related
sensitivity to the drug.

I myself can tell you it is true,,I lost my first puppy
when she was getting her ears cropped. This is
something I won't forget. I also had one of my dogs
given this drug while the vet was doing a small
procedure and he forgot about not using "Ace" ,
fortunately, I didn't lose my
dog this time, and I assure you,,prayer does work,,it
was a close one.
