Our four year old Jack Russell Terrier lost the vision in one of her eyes due to an injury. Bark Busters training experience has been more successful than any of the other training techniques we tried. By the end of the first training, barking at doorbells and for attention had greatly lessened. We have also been able to apply the techniques to other issues which have arisen and has been extremely helpful! Carolina's behavior has improved dramatically, her aggression towards other dogs was making it difficult to continue her normal lifestyle after the injury. Now we can take her to restaurants, shops, parks and beaches without having to panic about safety issues that could arise.
