Chew toys — stress relief and decompression
Chewing is not entertainment. It is a self-regulating behavior dogs use to manage stress, ease teething pain, and decompress after stimulation. The repetitive motion releases endorphins, which is why so many dogs gravitate toward a bone or a Kong after an exciting walk or a stressful event.
When a dog destroys shoes, table legs, or drywall, the underlying problem is usually unmet chewing need combined with stress. The ASPCA classifies destructive chewing as one of the most common behavior complaints, and redirecting it onto an appropriate chew toy resolves it more often than any obedience cue ever will.
Buying ultra-hard chew toys under the assumption that harder equals better. Excessively hard toys (real bones, antlers, hard nylon) are a documented cause of slab fractures in molars.
