May be you should read the full hadith and the commentry before asking this question.
As for the hadith cited in the question, it is narrated by Imam Ahmad, al-Bazzar, and al-Nasa’i thus:
One of the families of the Ansar had a camel which began to act difficult with them and not let them ride him. They came to the Prophet - upon him blessings and peace - and said: “We have a camel that is being recalcitrant and prevents us from riding him, and we need to water the date-trees and the plantations.” The Prophet said to the Companions: Let us go. They went and entered the enclosure where the camel was. The Prophet - upon him blessings and peace - walked towards it and the Ansar exclaimed: “Ya Rasul Allah! He acts like a [wild] dog and we are afraid for you lest he act violent!” The Prophet replied: “He has no grudge against me.” When the camel saw the Prophet it came towards him and fell prostrate in front of him. The Prophet - upon him blessings and peace - took its forelock and there was nothing more docile than that camel. Then he took it to work. The Companions said: “Ya Rasul Allah! This is a brute beast and it prostrates to you! We, who are rational, ought all the more to prostrate to you.” He said: “It is not fitting that any human being should prostrate to another human being and if it were, I would order woman to prostrate to her husband due to the greatness of his right over her.”
Finally, (3) it should be read within the context of other hadiths counterbalancing it with an emphasis on wives’ rights over their husbands and the overriding paradigm of the Prophetic model in the conjugal context. Otherwise all one gets is a caricature of marital duties as do those backwood tyrants who know nothing of marriage, nothing of the Qur’an, and nothing of Islam except the delusion that Allah loves for husbands to beat their wives!
