Nice close-ups (I hesitate to say macros, but they pretty much are). #2 is very nice, but the background is distracting -- it would be good to re-shoot looking in a different direction. #3 is very nice indeed, I think the logo is in exactly the right place!
I would never say something bad about a pic that includes a dog. lol but anywho the no.1 is my favorite. I really like the angle. Were it retouched tho? Because if no, I would put a lot more contrast to the image. It would look lots better!
