@elbrant I have wondered about the beagle as well, but he has very little scent drive. The yodeling and hypoallergenic are what made me wonder...
Thanks for your input! I am obsessed with the little guy.

I wonder if Banjo is part Basenji.

He is a curious and sweet little guy; I've never had a dog quite like him.

Hypoallergenic
Yodels/screams in crate
Very talkative
Barks at strangers to guard his property - this was learned after a year, he didn't bark really the first year
Wrinkly forehead
One ear up, one ear down
Doesn't care for other dogs but tolerates them if he must
Amazingly quick at learning tricks, he will "get" a new trick and have it memorized in less than five minutes
Short legs, but maybe this is another breed in his mix
Very cuddly, but on his own terms. I've forced him to become more affectionate, whoops. Can't help myself.
Does not like to lick faces.
Enjoys sitting on his side (see images)
Sometimes I feel like he behaves more like a cat
Likes to be "up" on things - will lay on the back of the couch
Likes to go for hikes
Perfect off leash - stays by my side or runs ahead and then back to me
Expressive eyes and face

By all appearances his father was a miniature pinscher (or min pin mix). I'm wondering what else he could have in him without doing genetic testing. I can't wait to hear what you think!

Some of these images were taken right before we adopted him. I've definitely been overfeeding him.
