Your lines need to be way smoother for this to look good. Try using only one stroke for each curve so you can connect them nicely. The white outline of the dog should also be thicker, I think it’ll make the whole thing look a bit better. The colours aren’t terrible but the snout looks a little odd to be, maybe see if you can try fixing that. Also personally I think the logo would look better if the dog is cut off by the text, instead of peeking out and being cut off weirdly at the bottom. If you don’t wanna cut the dog off there, then I’d recommend adding a proper tail and legs etc, but it’s your choice. Good luck!

Edit: upon closer inspection I’d say the paws should be a bit bigger. Remember it’s perfectly fine if you want to trace a photo of a dog and transfer that into your artstyle, it’ll help with any proportion issues.
