I just saw a story on Facebook about a dog acting strangely suddenly in the house, turns out they’d just installed smart plugs and smart bulbs throughout the house and the frequency was through the roof! Unplugged them all and the dog’s behaviour returned to normal. Just goes to show they hear/feel these things!
I have often wondered what our dogs hear when we have our TV on-- I have a sonic device that emits high frequency sound as a deterrent to baking-- I use it to discourage dogs that come at us when I walk my dogs but of course mu pups also really react to it-- I can't hear a thing and so yeah we live in a very different world than our dogs do sensory wise- sound-temp-colors- and a biggie... smells. We share their space and some of their world but who knows what we are missing??? Our dogs often going into a barking frenzy and rush the sliding glass doors to the outside and I see nothing there...who knows what they see/hear/smell?? Some cars drive them nuts to, others no response.. different worlds wrapped into a common space.
