Dogs eyesight is significantly inferior to ours. However, their sense of smell is about 1000x (don't quote me) more sensitive than ours. Which is why when you put a dog in a moving car and the window is open, the dog will stick his head out into the airflow as he gets a massive amount of stimulus by doing so.

Just chatting.
Define inferior, as dogs have better motion vision than us. Dogs see TV as flickering while we don't. Cats have better sight at twilight and better motion vision than us.
Is this proof of evolution.....
The smell thing is quite amazing...hence the term wee mail for dogs sniffing other dogs marking stuff

Some creatures see above our spectrum and some below our visual range.
Look up cats and dogs vision works. We know thing dogs see in colour where before we thought black and white
