Let me clarify a few myths and make a few points:
It is NOT haraam to own a dog, though it is not hygienic to keep a dog in the house.
It is NOT haraam to touch a dog or any other animal. If the saliva of a dog touches you or any part of your clothing, then it is required of you to wash the body part touched and the item of clothing touched by the dog’s mouth or snout.
It is incumbent upon all Muslims who own animals, whether for farming or work purposes or as pets, to provide adequate shelter, food, water, and, when needed, veterinary care for their animals. Arrangements must be made, if one is going to be away from home, to have one’s animals taken care of as well.
It is haraam to keep a dog or any other animal on a short lead for long periods without food, water, and shelter. Dogs need exercise and are social creatures who form organized “family” structures in nature. Dog owners therefore need to spend time daily with their dogs.
It is cruel, and therefore haraam, to keep any animal in a cage so small that it cannot behave in a natural way.
Fireworks cause untold suffering to most domestic animals because of their acute sense of hearing.
It is haraam to participate in any blood “sport,” like dog fighting and trophy hunting.
