- Does it work on all dogs?
- No. Ultrasound works best on puppies and young dogs; older or deaf dogs, and dogs already used to the sound, often ignore it.
- How far does it reach?
- Up to 25 ft, which suits one room or a hallway. Walls and furniture block the sound, so it won't cover a whole house.
- Can I change the correction level?
- No. It has one fixed ultrasonic tone and no intensity settings.
- What batteries does it take?
- It runs on standard batteries, but PetSafe does not publish a battery life figure, so expect to replace them regularly.
- Is it safe for people and other pets?
- The tone is above human hearing, but cats, rodents and some other pets can hear it. Keep it away from them if they seem bothered.
- When is it cheapest?
- It is $47.99 at Walmart as of November 8, 2026, the only new price listed. Watch for seasonal pet-supply sales.
