Well, which ones should be more popular than they are? Done responsibly of course. My vote to the larger Spaniels. Springers, water spaniels, Boykins and Clumbers. They could really make great dogs for people, but I don't see more around. Larger than the Cocker, for the medium dog people, some hair, but it is not normally of the GSD insane shedding type, and overall, rather friendly. Springers in particular should probably be more popular than Labs. Any of the bouncy exuberance that gets a lab evicted is at least less severe with the smaller dogs, but they still excel at all the same fun stuff.
