He's gonna be incredibly picky about his toys. We got him 5 different ones, to begin with. He ignores all of them, except for one. Now, little rawhide bones? That's a whole 'nother story…..
If he spent a lot of time in a kennel he might not be used to playing with toys. If he likes food-based toys you could try a stuffed kong or or something like these…

You can get them on Amazon or a lot of other websites. I saw the treat-ball at Petco.
And if you are interested in taking the puppy to a eye doc, I can get some recommendations for you. There are a lot of basenji people in the southern part of the state and I can get some references for you when I meet up with the basenji club this weekend.
