#16 LOVE LOVE LOVE this! Thank you! We took a while to figure out that there was a dog in the heart (the horse is easy to see), but now that we've "seen" it, we like it. My only suggestion on this one might be to try another style of dog which is more easily identifiable as a dog. That said this logo is definitely the front runner at the moment. :-)
#17 thank you for making the hood change. We like this a lot too. Still very much in consideration.
Like the fonts too, mixing caps with lower case, please stick with this style. :-)
