A reason is not the same as a purpose, of course. Reason and purpose are often confused, but plenty of things have no real purpose. A reason, on the other hand, is simply an explanation for something, and everything has an explanation.

There’s a reason for everything.

As the saying goes, everything happens for a reason, sometimes the reason is you make bad decisions
A dog may not possess the Buddha mind, but if they get a good run-up, they will possess that peanut butter sandwich on your mind.
