I'm trying to figure out if my 4 month old puppy , Pedro is a basenji mix and if so what he might be mixed with or other guesses to what he might be ? He's currently about 18 lbs , really sweet very affectionate to his mommy and daddy but shy around strangers, loves getting into stuff and chewing on what ever he can get his paws on. Seems to be smart and learning fast when is motivated.

We got Pedro from a shelter so we have no idea what his parents where but my vet thinks he's a shiba ini or basenji . He's about 4 months old and weighs about 18 lbs.From reading the personality description and from some of his features , i'm convinced he has some basenji in him, opinions ? What could he be mixed with , or if not basenji other guesses in what breeds?
