>>55164648I'm not quite sure, exactly. It's hard to draw a line in the sand and say "THIS exact height is too big". I just know I don't like city-stomping nonsense. That's too much. So, no dogs that are able to bring in the roof of a condo with one paw.
Around two to three times the height of a person is probably a good range. You could get decently bigger than that and I'd be fine with it, I'm sure, but really, it's just about the ideal of being the right size to pick someone up and snuggle them like a teddy bear.
