The Mohammedans didn't like him.

It is a part of their creed to hate dogs almost as much as pork, and to be touched by a dog means many prayers to Allah to wipe away the stain of contact.

But Little Wanderobo Dog was not conversant with the Mohammedan creed at first, and in his gladness and joy of life he embraced everybody in the waves of affection and friendliness that radiated from him like a golden aura.
The Somali gunbearers were disciples of Allah, and they began to kick at him before he was within eight feet of them.

Two of the tent boys were also Mohammedans, but they had to be more circumspect in their hostility.

Whenever Little Wanderobo Dog came around they would edge away, which gave the former a certain sense of importance because it was flattering to have a number of grown-up men fear him so much.
