Dogtra have produced another market leader with the Dogtra iQ No Bark Collar suited to the small dog from 5kgs. The first bark collar with ergonomic, less intrusive plastic conductive probes allows the collar to be left on for longer periods than traditional metal probes. 10 manual stimulation/static set levels allow you to find the correct level for your dog. Weighing only 105g, the iQ collar is a comfortable, light-weight solution for your small dogs nuisance barking. The iQ vibration learning system will give a vibration warning before any correction is given which allows less stimulation to be used over time. The bark recognition sensor ensures that the collar will only be set off by your dogs barking, yapping and even howling. If the collar is not activated for 10 seconds, it will go into a sleep mode to conserve the battery life. The detachable collar strap makes cleaning and replacing the bark collar easy as well.
