Throwing in my 2 cents here. :)
I have 2 dogs. One is a pug, the other a shiba inu. The Shiba is smart as a whip and a very pretty, happy go lucky girl. She is, however, very headstrong. She is the boss of the pug. LOL And only wants affection when SHE is in the mood for it. Otherwise, she has the attitude of "I'm busy dearest, come back later and you can pet me then." =P I've read that alot of people get shibas expecting them to be cuddly, lovey dogs all of the time but in my case, and as I understand it, they just are not that way usually. They are alot like cats. They are quite independent and active.
The pug on the other hand, is a lovable, loving, goofball. Very, very sweet boy. He is sleeping against my leg as I type this...he is quite affectionate and tends to be my little shadow. It is my understanding that this is typical of the pug breed.
If I ever add another dog to my family, it will be another pug. No, they arent pretty but they more than make up for that with their big hearts and their comedic/goof personality. :)
