The Jump Stopper is an adjustable pet-control aid, designed to help safely train dogs to stop jumping by way of a positive, humane technique, the company reports. A durable aluminum bar adjusts 6 in. (from 18 in. up to 24 in.) to ensure comfortable, secure use for different-size people and dogs, according to the manufacturer. The ergonomic easy-grips provide firm control during handling and are made of soft TPE rubber, the company adds.
