specifically, it does not seem to be able to detect entities that have an owner

example:

"minecraft:damage_sensor": {
	"triggers": [
		{
			"on_damage": {
				"filters": {
					"test": "is_family",
					"value": "wolf",
					"subject": "other"
				}
			},
			"damage_multiplier": 5
		}				
	]
},

if this is attached to a ravager for example, the ravager will get 5 times more damage than usual from all wolves unlike with other mobs. however it doesnt work if the wolf happens to be tamed
