If you see someone make this promise, walk away as they are not being truthful. I don’t see how this can be measured. Also, I am sure that no-one follows up on all their cases constantly after they have seen a case, especially if they are not offering an all-inclusive follow up service which is documented. Therefore, how do they know the problem has not re surfaced days, weeks or months later?
I have seen clients who have already seen “behaviourists” who have made this promise, so clearly these statements are not true. Sorry, I just can’t say that I can guarantee to fully solve your problem. After all, how many people with depression/anxieties, OCD, aggression are 99% cured? If we can’t do it with people, who are fully able to communicate their feelings, how could we possibly do this for dogs?
So, in answer to the above question, it does not mean they are better, only that they are not truthful.
