Yeah, they're more of a keep on a leash animal than a carry around animal. Though leashes don't work very well with things that can fly. They have a strong tendency to stay near their pack mates, which would be their owners. The crests and horns and stuff are also unique to the Halk, it is possible for a two Halks to have the same set of crests and horns, but it is extremely rare except in identical twins. So it's easy to recognize your own Halk even if it's in a large group of it's own breed.

Though some do get overtly rambunctious when they haven't seen their owner in a while and do a diving tackle into their owner. Kind of like a dog jumping on their owner when the owner comes home only with a bigger animal moving much faster.
