Humans don't notice any flickering of images if the screen refresh rate is faster than 55 hertz. However, dogs have better motion perception—they will see flickers up to 75 hertz. So, if we are watching an average TV show at 60 hertz, it will look smooth to us, but the image will appear to flicker for dogs.
Do dogs watch TV? Yes, but a pup's vision differs from that of a human. Christopher Pirie, a veterinary ophthalmologist at Cummings School of Veterinary Medicine at Tufts University, says that a dog with normal vision sees at 20/60 compared to our 20/20 rating.

I think a TV channel dedicated to dogs is a lovely thing. Whether or not it's any different to leaving on the news, time will tell, but the idea is great."
A: Yes. Humans can hear frequencies up to only 20,000 Hz, but dogs hear up to 45,000 Hz, and cats perceive frequencies of up to 64,000 Hz. Electronic devices are designed for people, and many emit frequencies that are distressing to pets but beyond what human ears can detect.
Although dogs can't identify themselves in the mirror, they still have some level of self-awareness and ace other self-recognition tests. They can recognize their own odor, and recall memories of specific events, Earth.com reports.

When you stare at your dog, both your oxytocin levels go up, the same as when you pet them and play with them.
So as long as a dog can smell, has healthy eyes, and can hear, they will most likely remember you no matter how long you've been out of their life. If you are wondering if your dog misses you while you're gone they don't have any knowledge of time but can experience separation anxiety.
How loud is too loud? Joshua Leeds, the president of BioAcoustic Research Inc., would say that anything above 85 decibels (dB) is too loud for dogs to hear as these sounds could cause hearing loss in dogs (source).
Dogs also have associated memory which mean they can in fact remember people based on their experiences associated with them. Your dog may have a memory of you leaving the house and due to the strong positive association with you mean they'll celebrate when you get home.
