We like #212. It's super-cute. The logo will ultimately need to be more 'square-ish', so could you stack the animals on top of the name? Also, could you change the ears on one of them to make them look more like a dog (so it looks like we are representing different pet types)? Lastly, is there an arrow (or some other flourish) that could be worked in to the design to represent 'back?'
Thanks!
