Okay he's cute, I certainly wouldn't be surprised if a mix... but without a DNA test, no way to really tell.
Barking... well basenjis bark, but for most it is a single Boof.. pause... booof. Not the bow wow wow rhythm of other dogs.
Oh shedding... they shed but nothing like my other breeds. We get a shed out in early summer. Otherwise, unless sick, not much shedding.
I have only had 3 basenjis... they all hated water, one so much that getting her to potty if the ground is we is a serious issue.
