It's hard to change what you've been doing, especially when you've already tried things that didn't work. That's why Woofy backs every order with a full 90-day money-back guarantee. Three full months to see whether your dog responds. If they don't — contact Woofy and get a complete refund, no questions asked, even if the jar is half empty. A company confident enough to put 90 days of risk on its own product is a company that believes in what it makes.
