PetSafe Unscented Spray Refill is compatible with PetSafe Spray Bark Control Collars and Spray Remote Trainers. Each can holds approximately 300-400 sprays. This formula is environmentally friendly and stain-free. 

3 oz. (88.7 mL) can.

To properly refill the collar the unit must be turned off. Make sure the spray can is upright while you firmly press the nozzle down into the refill port. Hold for 15 seconds and remove. If spray leaks out during refill, you may need to press harder to complete the seal.
