Cherry plants in general are considered to be poisonous for horses because of their leaves rather than the cherries themselves. Because the leaves contain a certain type of cyanide, they are bad for horses and can even be fatal if enough of them are consumed with a relatively short period of time.

It is okay to give horses cherries, but it is crucial to make sure that they do not eat the leaves which grow on the plants.

The fruit itself contains a lot of things that are great for both human and animal bodies, such as vitamin C and antioxidants.
