Sludge, dog all day long, my partner is 5 years into alzheimer's and we got ours two years ago, he is a constant delight, he's a miniature poodle, he's tough as old boots but very loving and intelligent,
on a bad day he makes me smile and the added bonus's are we get out to walk him every day (probably wouldn't bother otherwise) and he doesn't moult, poodle crosses are very popular for that reason so i guess you could find a rescue dog, there is also a dedicated poodle rescue website
