Dog looks to much like a pit bull. Please use German Shepherd and continue with design. Entry #23 is good but it needs to be dressed up. Also try it in more of an emblem style. Try integrating a house in the background maybe.
Thanks for the feedback. The dog was supposed to be a Rottweiler - maybe the head is a bit too big. I will try it with a German Shepherd and address your other comments as well.
#88 wow cool...play with the colors and font. silver and red please. Maybe the #1 instead of the word one. Mess with it a little some variations would be great. :)
