In Arab Gnomes and sayings :
They say : Guarder than a dog
Braver than a dog
Craver than a dog
Drosier than a dog
Insister than a dog
Thanker than a dog
Hearer than a dog
Who makes himself bony is eaten by dogs
Clouds are not hurt by dog barking
Convoys pass and dogs bark
Who fears a wolf prepare a dog

In Arab Literature:
Ali bin Al-Jahm says in his Divan (Collection of light poems) :

You are like a dog in keeping cordial     Like he-goat in severe troubles

Abi Nawas bewailing his dog says :
What a misery dog, master of dogs     Has kept me away from eagles
It has sufficed from the butcher     And for fetching slaver trader

A bequest of a nomad for his dog:
I do bequeath and commend well in the dog, since it has good deeds I do still praise. It tells me just where I am in dark night, if fire quenches.

Ibn Al-Roomi says in "lampoonery" in his Diwan :
Your face, Amro, is long     and in faces of dogs a length
Dog's ugliness is your merit     vanishes from but passes not away
In them are goods things     Protected by God and Prophet
A dog is loyal and you traitor     In you for his destiny infedility
It protects the sheep and goats     But, not protected nor powered

Ali bin Al-Jahm presented a dog and wrote in his Divan "Al-Munsareh":
I do bequeath and commend well in the dog, since it has good deeds I do still praise.
It tells my guest where I am in dark night, if fire quenches.

Amer bin Antara :
He used to have hounds, and was kind with their companionship , and when his dog died, he kept to its tomb until he died near it and lost his family for this.

Ab Abi Attiq says: (Abdullah bin Mohammed bin Abi Bakr El-Siddiq) to a man, what is your name? He said: Wathab. And, what is your dog’s name: Amro. Hence, Abi Attiq said:

If such was of success and blessing     Then he might have given reasons
And named himself Amro     And named his dog Wathab
