entry #4 - I like the profile concept except this dog seems to be hollering which is not an acceptable behavior. Perhaps a more dignified pose for a dog would work better. Also bring the phone number size up a little bit. I like the font used.
entry #4. I know design redone #42 however, I like the head shot better than full body. Is there a way maybe you could make it appear that the dog is holding his chest out which would make neck straighter with head held like it is proud of itself for having done something great (head posture is flat as if it were level with the floor, chin not held high)? (In dog world if a tail is tucked under the body it means the dogs if frightened, not a message I want to convey.)
OK here is just the head version. the head being slightly up should appear as if the dog is sitting looking up to wait for the next command from the trainer (obeident look).
