Pros and cons
Pros
- Long battery
- LED
- Low price
Cons
- 23 ft
- Dogs habituate
- Affects other pets
Limitations to weigh
- Find out why your dog barks first: boredom, fear, separation distress and alerting all need different fixes, and a bark collar can make fear or anxiety worse.
- Ultrasonic devices can bother other dogs and cats nearby, and many dogs get used to them; use them to interrupt, then reward quiet.
