The PetSafe Spray Refill cartridges are compatible with the PetSafe Rechargeable Spray Bark Collar PBC19-16370. The citronella-scented spray stimulates your dog's sense of smell when the collar is activated. The cartridge is easy to replace with no mess. Each cartridge delivers 35-40 sprays and the low spray indicator on your pet's collar indicates when the refill needs replacing.
The cartridge is 100% recyclable and the formula is completely safe for you and your pets.
