Thumbnail of Tilda


We adopted Tilda on January 16, 2010 from the North Shore Animal League. She weighed 35 pounds, and was at least three years old. She looks like a Lab / hound mix, and she behaves like a hound. Kath suggested the name Matilda ("mighty in battle"), a fine name for a dog who has survived abandonment and a broken leg. Two syllables makes a better calling name, so we shortened it to Tilda.

She barks too much.
