Those dogs are old.
I thought beagles were much smaller than that. (Alice weighs 18.7 pounds and stands 12 inches tall. How much smaller can you get?)
That one (meaning Ellie) has cloudy eyes.
This one (again Ellie) doesn't like being petted. (No kidding, someone used to beat her)

Alice is totally in tune with my moods, something I often forget but am reminded of when I'm uncomfortable and she starts whining.
