The PetSafe® Remote Spray Trainer is designed to help train your dog with a burst of spray. Whether you are taking an off-lead walk outdoors, or working on commands at home, this Remote Spray Trainer makes dog training easy. The collar has three training options – tone, vibration and spray stimulation—and a range up to 300 m, making this collar perfect for small hikes and public outings with your pup. At the push of a button you can send a signal to your dog’s collar. The collar includes both a citronella and an unscented spray refill cartridge, so you can determine which one works best for your dog. The recyclable and replaceable cartridges are convenient to use with no mess, and the collar is rechargeable – no batteries required. Designed to fit dogs 3.6 kg and up with necks up to 68 cm in circumference.
