SECURE AND HUMAN: No harm to your dog because this device is gentle on your pet by preventing it from shock or other physical damage. “Petic” collars do not use spray technology like Citronella or similar spray collars, as in some cases they can cause allergies. So we designed a painless solution based on sound and vibration technology to keep your dog safe!
PERFECT QUALITY FOR ANY SIZE: The bark control collar is designed for small, medium and large dog breeds. It can also prevent barking of small dogs! The automatic barking correction collar is designed for dogs weighing between 3.5 kg and 50 kg, with a collar from 17 cm to 55 cm (7 to 22 in). High quality materials will ensure durability and comfort during long walks or bad weather conditions.
