He has no sense of hygiene, he has not bathed in several months. he has hardly been eating much anyway and for the last day has refused anything. I am in fear he will starve or dehydrate. for the last six months or more he chooses to only sit in his room and chain smoke. He know wants nothing to do with anyone even his dogs. I want to know what I can do? I think he needs professional help, but he wont go willingly.
