bounded domain, meromorphic functions

Let $\displaystyle D$ be a bounded domain, and let $\displaystyle f(z)$ and $\displaystyle h(z)$ be meromorphic functions on $\displaystyle D$ that extend to be analytic on $\displaystyle \partial D$. Suppose that $\displaystyle |h(z)|< |f(z)|$ on $\displaystyle \partial D$. Show by example that $\displaystyle f(z)$ and $\displaystyle f(z)+h(z)$ can have different numbers of zeros on $\displaystyle D$. What can be said about $\displaystyle f(z)$ and $\displaystyle f(z)+h(z)$? Prove your assertion.

I do not see what example I can use here. I think what we can say is that they have the same number of zeros minus poles. I just don't see an example here. Thanks.
