If you want qualifications, I have a cousin with a Masters in Psychology. I wouldn't let him counsel my dog.
Two failed marriages, two lost jobs due to alcoholism, one new liver due to alcoholism, alienation from his family(his choice), living in his car for about 6 months. That's all I can think of at the moment.
I know not all of them are like this, just like not all elders are of the type you mentioned.
