I would opt for a mutt, they tend to live longer with far less health issues. They also generally have very unique physical characteristics which I think is my favourite part about them, they always look so dashing. I have a mix breed (Pitt bull - Rottweiler) and she is by far the best dog I have had the pleasure to own. Very intelligent and eager to please, as well as being very friendly to both humans and other animals. We got her for free from a family near us, and we get so see the parents regularly. I couldn't imagine a better scenario when adopting a dog.
I cannot persuade myself that a beneficent and omnipotent God would have designedly created parasitic wasps with the express intention of their feeding within the living bodies of Caterpillars.
