What is the origin of the Colby breed?

We owe the existence of the American Pit Bull Terrier to John Pritchard Colby, an American breeder who began to develop the breed from specimens of English Pitbull Terriers, managing to model the muscular and compact dog that we know today.

For this reason there are many people, especially in the United States, who know this breed by the name of Colby, which is not at all incorrect.

How is the character of a Pitbull Colby?

This breed loves to be in the company of humans. Its fierce and rough appearance is deceptive, as it is a friendly companion with a peaceful temperament, unjustly labeled on many occasions as a “dangerous dog”.

He has a high degree of self-confidence and is very jealous of his territory, two traits that in principle should make him a magnificent watchdog.

He has an affectionate temperament on general levels: if he barks it is not to press the alarm or dissuade strangers, but to welcome them.

However, his loyalty is beyond question, the Colby will not hesitate to act to defend his family against any threat or danger.
