Abu Hurayrah (may Allah be pleased with him) reported that Prophet (may Allah's peace and blessings be upon him) said: "While a man was walking on a road, he became very thirsty. He found a well and went down in it and drank. When he came out, there was a dog panting and eating moist earth out of thirst. The man said: 'This dog is so thirsty just as I was.' So, he went down into the well, filled his shoe with water and held it in his mouth until he climbed out. Then, he gave the dog water to drink. Allah accepted his deed and, thus, forgave him." They said: "O Messenger of Allah, are we rewarded for taking care of animals?" He said: "There is a reward for (quenching the thirst of) every living creature."
Another narration reads: "Allah accepted his deed and, thus, forgave him and admitted him into Paradise."
Another narration reads: "Once a dog was moving around a well, and it was about to die from thirst. When a prostitute from Children of Israel saw it, she removed her shoe, filled it with water, and gave it to the dog to drink. She was forgiven for that."Narrated by Bukhari - Narrated by Bukhari & Muslim
