Naming animals or giving animals special names that are different from what they are usually called
Question

                Is it permissible to name animals?.
Praise be to Allah.
    There is nothing wrong with giving animals appropriate names. 
    Al-Bukhaari (2872) narrated that Anas (may Allah be pleased with him) said: 
    The Prophet (blessings and peace of Allah be upon him) had a she-camel 
    called al-‘Adba’, that was never beaten in a race. 

    Al-Bukhaari (2627) and Muslim (2307) narrated that Anas (may 
    Allah be pleased with him) said: There was a disturbance in Madeenah, and 
    the Prophet (blessings and peace of Allah be upon him) borrowed a horse 
    belonging to Abu Talhah that was called al-Mandoob, and rode it. He said: 
    “We have not seen any cause for panic, and we have found it (the horse) to 
    be swift-footed.” 

    Al-Baghawi (may Allah have mercy on him) said:

    This shows that it is permissible to name animals; it was the 
    custom of the Arabs to give animals and weapons names by which they would be 
    known if they were to look for them, apart from ordinary names (nouns).

    al-Bukhaari gave this chapter the title: Chapter on Naming 
    Horses and Donkeys. 

    Then he narrated a number of hadeeths concerning that, such 
    as the hadeeth which says that the Prophet (blessings and peace of Allah be 
    upon him) had a horse that was called al-Laheef (2855), and he had a donkey 
    that was called ‘Ufayr (2865). 

    Al-Muhallab said: The fiqh concerning this matter is that it 
    is permissible to give names to animals other than what they are usually 
    called.

    Abu’d-Darda’ had a camel called Damoon. Narrated by Ibn 
    al-Mubaarak in az-Zuhd, 1173 

    Abu Qataadah had a horse called al-Jaraadah. Narrated by 
    al-Bukhaari, 2854 

    Al-Manaawi said, after mentioning some of the reports that 
    were narrated concerning this matter: 

    This shows that it is acceptable in sharee‘ah to give names 
    to horses, mules, donkeys and other animals by which they may be told apart 
    from others.
