About The Boxer
General Appearance:
The ideal Boxer is a medium-sized, square-built dog of good substance with short back, strong
limbs, and short tight-fitting coat. His well developed muscles are clean, hard, and appear smooth
under taut skin. His movement denotes energy. The gait is firm yet elastic, the stride free and
ground covering, the carriage proud. Developed to serve as guard, working and companion dog.
He combines strength and agility with elegance and style. His expression is alert and his
temperament steadfast and tractable.

The chisled head imparts to the Boxer a unique individual stamp. It must be correct proportion to
the body. The broad, blunt muzzle the distinctive feature, and great value is placed upon its being
of proper form and balance with the skull.

For a more detailed description of the Boxer standard see the American Kennel Club web-site.
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 annoucement was placed in the cardiology section entitled "Acepromzaine
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 annoucement suggesed that Acepromazine should not be used in dogs of the
Boxer breed because of a breed related sensitivity to the drug.

This drug is the most commonly prescribed tranquilizer in veterinary medicine. It is also used
orally and is prescribed for owners who want to tranquilize their dogs for air or car travel. I
would strongly recommend that Boxer owners avoid the use of this drug, especially when the
dog will be unattended and/or unable to receive emergency medical care if it is needed.
