Great design. Consider the places this logo will be used, billboards, signs, flyers, social media, etc. A logo must be legible in all formats, so the thin lines used for the illustration of the pup risk being visually illegible. Especially with your bold typeface, I would recommend simplifying the illustration and making it more visually legible!

The black outline of the circle and the I are conflicting here. Be conscious of where your lines intersect and cross! Repeating that logo element twice is also a bold choice to make, finding a good visual balance in the logo using those symbols is another thing to look at! Otherwise, great work.

Try using the drop shadow effect in photoshop to create a more realistic shadow!

Looks great! I'd look for some more balance though. The bubble has a lot of visual weight that balancing out could benefit the logo in a big way!
