10 Commandments for Pet Owners
-My life is likely to last 10-15 years. Any separation from you will
be very painful.

-Give me the time to understand what you want from me. Do not break
my spirit with your temper,
though I will always forgive you. Your patience will teach me more

-Please have me spayed or neutered. It's better for everyone.

-Treat me kindly, my beloved friend, for no heart in the entire world
is more grateful for your kindness than mine.
Don't be angry with me for long, and don't lock me up as punishment.
After all, you have your job, your friends,
and your entertainment. I only have you.

-Speak to me often. Even if I don't understand your words, I
understand your voice when it's speaking to me. Your voice
is the sweetest sound I ever hear, as you must know by my enthusiasm
whenever I hear you.

-Take me in when it's cold and wet. I'm a domestic animal and am no
longer prepared to the bitter elements. I ask for little, gentle
hands petting me, my bowl full of water, and good food so I can stay
well. By your side I will

The MCOA is dedicated to the health and welfare of the English Mastiff breed conserving its unique breed function as a gentle giant companion and family guardian.

A pure bred dog of this type offers to his owners that he will be of a specific size, shape, color and temperament.

The predictability of a breed comes from years of selection for traits that are desirable and away from those that are undesirable. However, when a breed standard or type is set, those animals within that set have less heterozygosity than animals in a random population.

A so called “American Mastiff” is nothing but a mixed breed when the English Mastiff is crossed with an Anatolian Shepherd or whatever, the resultant first generation offspring, because it is a gamble, the offspring become an unpredictable mix. Coat, body shape, height, color, head etc become a veritable crap shoot. Behavior and temperament, the most essential character of an English Mastiff, varies and centuries of breeding for predictable behavior is lost when breeding to a dog of questionable temperament.

The MCOA is opposed to the cross breeding of pure bred dogs for the purpose of whim and fancy. These mixed breed dogs are not exempt from but more prone to the known genetic diseases of both breeds. They offer none of the advantages that owning a pure bred has to offer.

We urge you to avoid this temptation to purchase a “designer Mastiff”. Be a prudent and informed bu
