Congratulations! She does look a bit like a Beagle or similar because of her ears and larger nose--not as narrow as a chihaihua! Cute, and being a mix might mean she is a little more sturdy, especially at 10 pounds. Does she have a beagle or a chihuahua tail? She also looks lap-sized, which is nice.
So maybe she is a Cheagle??? Or maybe a Beahuahua??
