Yes, your dog's testicles should be approximately the same size. One can be a tiny bit smaller, but there should not be a huge difference. Your dog needs to be seen by a veterinarian as he could have a testicular tumor, a testicular torsion, an abscess or orchitis or brucellosis. Please take him to a vet ASAP.
