Hi there. Here's a concept I propose for your company's logo.
To communicate a working dog, I thought of the lab rat who is usually depicted running on a wheel. But instead of a "working" rat, I used a dog. This arrangement of the elements not only makes the logo mark unique and memorable but it also communicates cleverness, dedication and hard work.
The logo is still recognizable even when reduced to small sizes, e.g., a favicon, and even in black & white for printing to your business cards and other collateral.
If you see potential in this concept, let me know and I'll be more than happy to update the design for you.
Thanks in advance for your time reviewing my submission.
