Dogs are "haram" to be kept (except as hearding or guard dogs) and are not allowed in one's home. But what about dogs trained to help disabled people(blind,hearing impairment,seizures......)? They need to be close to their owner and living with them in order to be of help. Could those dogs be kept indoors? Sunni point of view please but would like to know about others as well.
Generally, dogs should be avoided because their saliva is impure but trained dogs for helping disabled/blind people are allowed because that is a necessity. However, they should be taught to not lick their owner.
This is the mainstream Sunni point of view.
