Do animals and humans have the same blood? If not
.. why? What makes them different?

No, they do not have the same blood.

The specific thing that makes makes them different is our different genes.   More broadly, it’s our different needs that make us different.  

You will find that most creatures have the same basic elements to their blood - plasma, platelets, red blood cells, white blood cells, etc.   But what those cells look like and what they can do is very different in different animals.   Camels, for example, have oval-shaped red blood cells where we have disk-shaped red blood cells.   This is so that camels can drink and take onboard huge amounts of water all of a sudden without their RBCs bursting.  Dolphins and whales have red bloods cells shaped in a way that maximises oxygen carrying capacity, more than ours do.  This allows them to hold their breath far longer than we do.
