That's hard to say without being able to examine and monitor the testicles. It's possible this is congenital. If Digby is not a breeding dog, an undeveloped testicle is not a big concern (though I do recommend to have him neutered). A less common cause of a size difference is a torsion or infection. A veterinarian can get an idea of what is happening with an exam. I hope this helps.
