  By using the canonical Hamiltonian method, we obtain the mass and entropy of
the black holes with general dynamical coupling constant $\lambda$ in Ho\v{r}
ava-Lifshitz Gravity. Regardless of whether the horizon is sphere, plane or
hyperboloid, we find these black holes are thermodynamically stable in some
parameter space and unstable phase also exists in other parameter space. The
relation between the entropy and horizon area of the black holes has an
additional coefficient depending on the coupling constant $\lambda$, compared
to the $\lambda=1$ case. For $\lambda=1$, the well-known coefficient of one
quarter is recovered in the infrared region.
