The method is easy to use and we saw immediate results. The practices are easy to do. We have a rescued dog that we have had for 6 years. I have not been able to bond with her due to her aggressive nature and barking. She had been in a training class where she earned her "certificate." After that she had been to a vet behaviorist for evaluation and medication. This did not cure her of the barking and aggression. With Glenda and the Bark Busters sessions we have seen a change in the dog's behavior as we her owners have become trained in methods to effectively deal with these problems. Not only are we pleased with the results we have observed in our dog's behavior but the dog seems calmer and more peaceful. This was an investment well worth making.
