We like the idea of a simple, suggestive line-drawing-style logo (similar to the "Six Figure" logo included above) that includes a dog (or dogs) and a human runner. We do NOT want the dog(s) to appear like it is pulling or leading the runner, but rather the dog(s) should be slightly behind or abreast to suggest that it is having a great time but the runner is the leader. Both dog & runner should be running left-to-right. We know how awkward humans can be to depict in logos, so feel free to try the human from the waist down only, or something more suggestive... like a leash but no runner, etc..
We want a more sleek/short haired dog as opposed to a bushy or long-haired breed. Ears should be floppy instead of cropped and tail should be natural instead of cropped.
It should suggest the vigorous movement that distinguishes us from normal dog-walkers. In other words, both the human and the dog should look like they are running, NOT walking.
In general we want something more elegant and classy as opposed to cartoonish and kitschy, but clever is definitely encouraged. We are attracted to ombre/gradient elements, but not if it looks too busy.
All this being said, we are not designers and we would love to be wowed by something that would never occur to us, so feel free to disregard these suggestions if you're on to something amazing that is different.
