Goats are friendly, charming and intelligent..... don't let anyone tell you otherwise.

Humans domesticated by goats 11,000 years ago 

Estimates vary but it seems that humans were first domesticated by goats between eight thousand and eleven thousand years ago in the mountains of Iran. Being sociable, adaptable, intelligent and able to eat almost anything humans were an ideal subject for domestication and have been captivated by goats ever since.

Of course the goats had to learn to handle dogs because they were the very first wild animals to take over human homes ( caves) which were warm, dry and littered with nourishing kitchen scraps. They handle dogs by never turning their backs on them and head butting to keep control. This means that the goats can take their humans  and dogs for country walks and picnics  on fine days as above.

Darwin's cousin, Francis Galton noticed that domesticated animals were only a limited number of species with certain behavioural traits making them suitable for domestication; they should be sociable (herding), the young should bond quickly and strongly with their parent and should be flexible in their dietary requirements. Galton's requirements for domestication.
