a bit OT: Dogs and modern TVs

Our dog has several puzzling “quirks” and I’m beginning to wonder if they’re all related.



She always leaves the room the moment we turn the TV on, even if muted.



She gets spooked by whistles being blown and runs off in a panic.



At the same point on her evening walk she gets very nervous.



Today I realised that the point where she gets nervous has a lot of bats flitting around.



Is hyperacusis in dogs a thing?

A former colleague of mine had a dog that was not allowed to watch any David Attenborough or other wildlife programmes. Reason: every time the dog saw a bear it did a massive dump there and then.

Didn't have time to get to the woods then :-)

My mutt used to wag his tail when animals came on screen then run round to the back of the TV looking for them when they went off screen.

Dog whistles are often too high pitched for humans, but I don't know whather the sound would be loud or just unusual.

Modern TVs of course don't have the high-pitched line-scan frequency (that I could just about sense when I was much younger) that a dog might not like. Switch-mode power supply frequency?

Its possible

Generally these days SMPS's are well over 50kHz tho
