So the idea behind JPEG is the same as behind MP3: we filter out what we don't perceive. I wonder if other species would look at our images or listen to our sounds and register with horror all the gaping holes everywhere.

Gaping holes seems unlikely, more loss of detail or shifted colors. You can experience something like that by using plugins which simulate CVD / color blindnesses.

My dog doesn't react to familiar voices over the phone at all. The compression and reproduction of audio, while fine for humans, definitely doesn't work for her animal ears.

  Have you tried it with uncompressed audio? Have all the times when your dog could recognize your voice also been times when you were within smelling range?

    It's pretty hard to avoid uncompressed audio. Even if it's PCM, there's almost always a lowpass filter, either explicitly in the input/output processing, by the sampling rate, or from the physical limits of the mic and speaker. Everything is tuned for human audible range, so dogs will miss out on the higher frequency stuff. Humans did ok with POTS@8kHz with a 300-3400Hz band pass filter though. The internet says dog hearing goes up to ~ 60 kHz; most audio equipment tuned for humans won't go anywhere near that, but probably cleanly carying high frequency up to the limit of the equipment would be better than psychoacoustic compression tuned for humans.

  Could also be the speaker and volume.

  What does frame rate have to do with being able to recognise a creature? If I watch a video in 10fps it looks shite but I still recognise everything on screen

    It's about being able to perceive it as a "living" moving creature and not something different. You can understand something below the perception threshold is supposed to be a creature because you both have a far more advanced brain and you've been exposed to such things your entire life so there's a learned component; but your dog may simply not be capable of making the leap in comprehending that something it doesn't see as living/moving is supposed to be representative of a creature at all. I've personally seen something adjacent to this in action, as I had a dog over the period of time where I transitioned from lower framerate displays to higher framerate displays. The dog was never all that interested in the lower framerate displays, but the higher framerate displays would clearly capture his attention to the point he'd start barking at it when there were dogs on screen. This is also pretty evident in simple popular culture. The myth that "dogs can't see 2D" where 2D was a standin for movies and often television was pervasive decades ago. So much so that (as an example) in the movie Turner and Hooch from 1989, Tom Hanks offhandedly makes a remark about how the dog isn't enjoying a movie because "dogs can't see 2D" and no further elaboration on it is needed or given; whereas today it's far more common to see content where dogs react to something being shown on a screen, and if you're under, say, 30 or so, you may not have ever even heard of "dogs can't see 2D".
