In order for a dog not to see a television, though, the persistence "timing" would have to be *dramatically* different from that of humans. Consider that even at half the normal refresh rate, a television will still appear to produce a picture, it will just be very irritating to look at.
Also, CFL bulbs still flicker at the usual 60 Hz since they are powered by the same mains power as other fluorescent bulbs, but their phosphorescent coating allows them to maintain some glow during the low part of the cycle thereby making the flicker a little less apparent.
