Helps stop nuisance barking quickly and safely!
The HUSH! PUPPY emits a safe, high frequency sound pulse which disrupts your dog`s barking sequence. An electronic timing circuit ensures that it does not go off at rapid alarm or intruder-type barking. You can adjust sensitivity and stimulus controls to meet your dog`s individual needs. Approved by veterinarians and animal behaviorists as one of the safest and most effective methods of controlling this problem.

Uses 9-volt battery (not included).

Recommended for dogs under 40lbs.

Collar fits all sizes 2 3/4"w x 1 1/2"h x 1 1/4"d.
