Love the name! He looks kind of like my Mr.T (only T doesn't have any white on his nose). From one tri owner to another, your basenji is very handsome................just don't tell T know I told you that! Its an older photo, but T is very much the spitting image of this photo even now.
I wish I knew how to change the orientation of the pics, so sorry.
It depends on what software you have available, e.g. on my computer it took only a second to do this with Windows 10 picture tools.
If you are using a phone, it would depend on whether it is iPhone or Android. And you can also do it on line.
