Well, if one had a choice in this matter.........a Bernese Mountain dog, or a Newfoundland, would greatly appeal.
And West Highland terriers are also worth thinking about.
Newfies are amazing dogs, aren't they? In spite of their somewhat intimidating size, they apparently have quite nice temperaments and can be quite gentle with people.
Westies are cute and fun little dogs. Former neighbors had one and I always enjoyed greeting him and petting him as he and his mistress were going out for a walk.
Today's going to be so much fun around MR as we all sniff out each other's breeds....
