Things Dogs can see that we can't

[Catherine]

I did not know they can see ultraviolet light. I knew dogs could see differently. Now it seems they can see more.

Let's face it, dogs are superior to us. They are better people in so many ways and they seem to want to help us.  Good thing they are on our side. If we would work with them more our lives would be better.

I understand some dogs can detect cancer and we know dogs can sense seizures. 

Wouldn't it be fun to  design things for dogs that tap into the visual differences. They could have patterns that only a dog can see and they could figure out what patterns dogs like.  It is a whole new concept in dog supplies.
