#4 -- I like the font quite well. The Dane does not quite have the right shape / structure for the breed. You can find images of Danes in a "down" on "play bow" (butt up in the air online". What I don't see here is interaction or action between the Dachshund and the Dane.
# 3 -- I like the layout of the letting such that "the" is not necessary the focal point. Againt he Dane body shape is off. Also not seeing any of the green coloring.
Both seem to be missing the playful component.
Other colors can be added as needed for the dogs if neccessary.
