Underneath these rough diamond heavyweights is a very small heart.
The Mastiff is a very gentle and childfriendly caring gentleman.
He loves an outlined life and makes the inventory of his property at the beginning of each day.
He trusts that all activities of the day will take place in a normal pattern and is deeply unhappy if this is deviated.

Despited its special suitability as a watchdog (not to be confused with protectiondog) the Mastiff is a very, very quiet breed.
Most of the day you’ll find him lying down.
Logical really, because there usually isn’t so much too watch for, and just watch to watch, NO, that’s goes too far for him.
He watches only where needed and rightly so.
So there is our friend, lying with his heavy head between his frontleg.
Nothing moves, except his eyebrows which go up and down constantly, don’t be fooled, he keeps watch.

This carefree lifestyle gives the impression that the Mastiff requires little or no movement, nothing is less true…
The huge muscles that he has has to built, to be able to function fully and that can only be achieved when getting enough exercise.
Does this become a daily task, than he will accomplish this with the greatest pleasure.
So it’s not the size of the gard that counts (he doesn’t use it anyway), but the time you go out together will.

The Mastiff is a social dog. He can easily live in a pack without any serious problems arising. 
With other races he is quiete smooth, but on the conditions that the other animals are social too.

Furthermore, the Mastiff is incredibly devoted to his family and he loves children like no other. 
He will protect his family appropriately at all times and doesn’t wish anything in return, 
maybe just that he will be treated as a full member of the family and he certainly doesn’t like to be put into a pen.
If you get a Mastiff and put him in a pen, he will wither away from grief and become very shy.
He will only defend his pen, but certainly not his “loved ones”.

To fulfill the trustfunction as a watchdog, it is necessary that the Mastiff is a large dog that just by his appearance deter potential intruders. 
Height and weight are not included in the standard as it would only result in a striving for heigth.
The higher the better, only if provided with sufficient mass, arising from a massive spring of rib.
The heigth will be more to come from chest depth than leg length.
Heigth and weigth are fine as long as the dog runs well, stands good on his feet and has heavy bonestructure to support this all.

The Mastiff should in any case, alway be longer than high!
A length stemming mainly from the far reach from behind the floating ribs.
He has very deep and broad loins flanks. (a tucked up belly is objectionable).

The heaviest dog ever, the Mastiff Zorba Aicama or la Suza, in 1989, accoring to the Guinness Book of World Records, weighed 142 kg.
with a heigth of 88 cm. 
You should not consider this as reference point.
A male of 80 kg. with a height of 75 cm. will be seen as very considerable.

The head must be very broad and should give a square impression.
The skull will be flat under normal circumstances, but wrinkled when its attention is drawn.
The stop is clear and over the whole length of the muzzle, full and relatively short, which never be less as 1/3 of total length of the head.

The Mastiff has short hair, but the coat is slightly longer on neck, back and shoulders.
You can choose the following colors: Fawn, Brindle and Apricot.
When breeding, the different colors are combined.
Colour is a matter of taste. Let this never be crucial in any choice. (People buy cars not only for its beautiful color.)
Whatever color a Mastiff has, he must absolutely have a black mask, that cover the entire front of his head.
Black ears and dark eyes. Both small.
Further can be said that the Mastiff is a moderate eater and certainly not a guttler.
It is a relatively healthy breed with few ailments.

Finally, a warning: Beware of the Mastiff-virus! Once a Mastiff, always a Mastiff.
