It certainly might still bloom, most Dens are pretty tough and it doesn't look like the growth is chewed all the way through. I hope it does, capituliflorum is an awesome and IMO underappreciated species!
The squirrels at my place mostly went for cirrhopetaloid Bulbos and over the course of a week totally destroyed several nice specimens I'd had for years. They also went across my bench and took chunks out of just about anything with a succulent pseudobulb or leaf.
I used to find squirrels cute and charming, now I just look at them as larcenous tree-rats with gaudy tails...
I was able to prevent more damage to my plants by covering them with bird netting, the cheapo kind with a plastic grid of 1 cm squares. It would probably work best on top of a frame to hold it up off the plants, but I just laid it right on top of my plants and bench and that worked fine. If they'd been determined enough they could have still gotten to the plants but I guess they didn't want to tangle with the netting. I hope this helps!
