You're probably right. I'm more a fancier of the hound breeds, myself, and prefer a big dog. But there's a certain fascination in the little rodent-like things. I was recently given a half-Chihuahua, half-lemur critter and she has a good bit of charm as long as you don't expect her to kill a burglary or round up a herd of cattle as a real dog would. Meanwhile, it's pretty cute to have an Eohippus-type creature following me around.
I am not a dog person, if I had been around when canines were being domesticated it would have never happened.
However, I am partial to Rhodesian Ridge-backs.
My daughter has a couple of Catahoula hounds, they are ok. Very loyal to the kids and have the energy to keep up.
I do like the “rodent-like thing” description.
I used to have a friend with horses. Her farrier had a chihuahua. Every farrier has to have a dog. This was his.
