Let remind you that the Hadiths that speak about killing animals in Hajj, promot the killing of them all times even in Hajj (where it's sinful to hunt animals as a whole for Food).
Narrated Hafsa: Allah's Apostle said, "It is not sinful (of a Muhrim) to kill five kinds of animals, namely: the crow, the kite, the mouse, the scorpion and the rabid dog."
Sahih Bukhari 3:29:54
Now apart from hajj..
Maimuna reported that one morning Allah's Messenger (may peace be upon him) was silent with grief. Maimuna said: Allah's Messenger, I find a change in your mood today. Allah's Messenger (may peace be upon him) said: Gabriel had promised me that he would meet me tonight, but he did not meet me. By Allah, he never broke his promises, and Allah's Messenger (may peace be upon him) spent the day in this sad (mood). Then it occurred to him that there had been a puppy under their cot. He commanded and it was turned out. He then took some water in his hand and sprinkled it at that place. When it was evening Gabriel met him and he said to him: you promised me that you would meet me the previous night. He said: Yes, but we do not enter a house in which there is a dog or a picture.
Then on that very morning he commanded the killing of the dogs until he announced that the dog kept for the orchards should also be killed, but he spared the dog meant for the protection of extensive fields (or big gardens).
Sahih Muslim 24:5248
Abu Dharr reported: The Messenger of 'Allah (may peace be upon him) said: When any one of you stands for prayer and there is a thing before him equal to the back of the saddle that covers him and in case there is not before him (a thing) equal to the back of the saddle, his prayer would be cut off by (passing of an) ***, woman, and black Dog. I said: O Abu Dharr, what feature is there in a black dog which distinguish it from the red dog and the yellow dog? He said: O, son of my brother, I asked the Messenger of Allah (may peace be upon him) as you are asking me, and he said:
The black dog is a devil.
