Avoid rawhide since cavaliers tend to choke. Avoid bones that have a hole due to the teeth and jaw getting stuck. Try and avoid treats made outside in China due to recalls and making pets ill. Avoid some dental bones that the dog can take big chunks out of. I would avoid processed chicken or beef. Stick with dehydrated liver, any treat that has real food in it not too many processed foods and additives. Bocce is a good brand. Sweet potato treats made in USA are really good treats.
