It certainly looks like your dog has completely normal and healthy testicles, as far as I can possibly say without palpating them. It is quite normal that one testicle is a little bit bigger than the other. The skin looks normally pale pink, ie not red and inflamed, and the scrotum appears to have normal hair. So, I do not think you have to worry about Bear's testicles being abnormal or diseased.
