All creatures are the creation of Allah Taمla and do deserve the recognition of being a creation of the Almighty. As much as Muslims detest even the sight of pigs, it is the creation of Allah Taمla - and because Allah has placed life into it, we cannot inflict pain nor torture the pig.
Similarly Allah Taمla created the dog from among His creation. This does not mean that we should love the dog. It is perhaps the indoctrination of the Western culture that the dog is 'Man's Best Friend'. The theory that 'dogs are very dependent on Human affection' is a myth - again culture and custom has helped to develop this unnatural behaviour.
Allah Taمla the Creator of this Universe, having created the dog, would surely have known that the dog requires Human affection and love to exist in this world. Rasulullah (Sallallaaahu ءlayhi Wasallam) would have advised us, Muslims, to keep dogs as pets. On the contrary, we are instructed not to keep dogs as pets and 'love' them as exemplified by the non-Muslims. Remember, our life is structured and bound by the Shariah, i.e. the Noble Qurمn and the beautiful example of Rasulullah (Sallallaaahu ءlayhi Wasallam). Consider these Ahaadith:
Hadhrat Abu Talha (Radhiyallaahu ءnhu) reports that Rasulullah (Sallallaaahu ءlayhi Wasallam) said, "Angels do not enter a house wherein there is a dog or an animate picture." (Sahih Bukhari Hadith no. 2986)
Hadhrat Ibn Abbas (Radhiyallaahu ءnhuma) reports from Hadhrat Maimoona (Radhiyallaahu ءnha) that once Rasulullah (Sallallaaahu ءlayhi Wasallam) became sad; and said that Jibra'eel (ءlayhis Salaam) promised to meet him at night but did not turn up. "By Allah what has kept him back," said the Prophet (Sallallaaahu ءlayhi Wasallam). Then he realised a puppy was under his bed. He ordered that the puppy be removed and the area be sprinkled with water. In the afternoon when Jibra'eel (ءlayhi Salaam) came, Rasulullah (Sallallaaahu ءlayhi Wasallam) enquired as to the delay. Jibra'eel (ءlayhi Salaam) said that we, the group of Angels, do not enter a house wherein there is a dog or pictures. (Sahih Muslim Hadith no.3928)
In the light of these Ahaadith and other narrations it is not permissible to keep dogs as pets. The household is deprived of the Mercy of Allah Taمla.
However, Jurists have stated that it is permissible to keep a dog for security purposes, farming and hunting.
The saliva of a dog is Najis (impure). if it touches the clothes or body, that portion also becomes impure and must be washed.
and Allah Ta'ala Knows Best
