Can you identify these (possibly) LEGO horses?
Those horses look like legit LEGO-brand horses. 

Specifically:

White Horse with Black Eyes, White Pupils and Dark Orange Bridle Pattern: 4493c01pb04



Black Horse with Black Eyes Circled with White, Brown Bridle Pattern: 4493c01pb02



In order to be extra sure they are genuine LEGO, look for the "LEGO" stamp on the inside of the hollow studs on their back where the saddle goes (it's a little hard to see).

These horses each came in a fair number of sets. Check the BrickLink links for a list of possible sets. If you are sure they both came in the same set, these are the sets both came in:
