Everyone has an option to post on our website what their experience is. The reviews that are negative are few and far so they may not be on the first few pages of the reviews, but we do not eliminate those.
We are also on TrustPilot (https://www.trustpilot.com/review/www.vetionx.com) - a website that allows reviews to be posted that companies have no control over. We can respond to those reviews and that is it.
Yes, you are right, not every pet will respond the same to treatment. There are many factors to consider when treating a pet. Age, how long they have had their ailment for, diet, supplements given, environment, other types of treatments provided, and more. We take this all into consideration when a pet does not respond. We also have a vet available to answer questions free of charge through our website.
We hope you consider trying our product, we do offer a 60 day return policy which is on our website that you can review: http://www.vetionx.com/return_policy.php
