  The prospects of searches for anomalous production of hadronically decaying
weak boson pairs at proposed high-energy muon colliders are reported. Muon-muon
collision events are simulated at $\sqrt{s}=6$, 10, and 30 TeV, corresponding
to an integrated luminosity of $4$, $10$, and $10$ ab$^{-1}$, respectively.
Simulated $\mu\mu\rightarrow\mathrm{W}\mathrm{W}+\nu\nu/\mu\mu$ events are used
to set expected constraints on the structure of quartic vector boson
interactions in the framework of a dimension-8 effective field theory.
Similarly, $\mu\mu\rightarrow\mathrm{W}\mathrm{W}/\mathrm{Z}\mathrm{Z}+\nu\nu$
events are used to report constraints on the product of the cross section and
branching fraction for vector boson fusion production of a heavy neutral Higgs
boson decaying to weak boson pairs. These results are interpreted in the
context of the Georgi-Machacek model.
