Add new baloo 48px icon and update the preference-desktop-baloo
icon to the same style.
Some of my thoughts on the new preferences-desktop-search icons (D24959#554523) also apply here: I think that lines of the magnifying glass symbol feel a bit too thick for Breeze, and IMO the large glass-to-handle ratio doesn't feel quite right, although I realize you have to fit that paw symbol in there. Also, this kind of icon is a classic candidate for the 45° degree shadow.
I would also try making the paw symbol a bit more simple, perhaps by removing the ellipses between the bottom and the claws themselves, in order to make the design less visually noisy. Then it might also be possible to make the paw smaller in the 32px version.
Maybe we can also come up with a more interesting background than a blue circle, which is quite bland, considering this is an application icon.
