Most dogs do best with both: a flat collar for ID tags and a harness for walks. A harness is the safer choice for pullers, small and flat-faced breeds, and dogs with neck or back problems. A collar works for calm leash walkers. Here's how to choose.
E-collars and shock collars use the same basic technology: electric stimulation from a remote. The difference is control. Modern e-collars offer 100 or more fine levels plus tone and vibration, while cheap shock collars jump between a few harsh settings. Vibration collars use no stimulation at all.
HEPA filters trap pet dander and hair, activated carbon absorbs pet odors, and ionizers only make particles stick to walls and floors, sometimes while producing ozone. For pet owners, the best air purifier pairs a true HEPA filter with plenty of carbon.
