There is something to be said about simplistic line drawings. I like all of your logos. However, I'm not too keen on the P being in the middle of the dog.

Placement of text and graphics can be tricky. I think you have some solid ideas but futz around with placement a bit more... here's a couple I mocked up real quick... hope it inspires some more thoughts.



Might also want to play with adding a leash and attaching it to the expertise or maybe a tail in the full dog image. Just some ideas to kick around. Otherwise great job. Keep it up!
