Ruff Greens is a relatively new brand that focuses on its core dog supplement. Despite their young age, Ruff Greens has grown in popularity and is used by thousands of dog owners. The core supplement is designed to be combined with a dog’s core diet of dry or wet food but can also be taken by itself. Ruff Greens appears to be associated with Doctor Dennis Black, who is a Naturopathic Doctor. However, it is not clear whether Doctor Dennis Black is the one who has formulated Ruff Green’s products or if he is merely the owner. Ruff Greens is produced within the United States at an FDA-registered facility. It offers a subscription service that allows dog owners to have their products shipped directly to them at regular intervals. However, some customers have had complaints about the ‘free trial’ or ‘free sample’ that Ruff Greens offers new customers. While the initial trial is free, Ruff Greens will charge and ship a full-priced product to you within 15 days if you do not cancel the service. Many customers do not realize this or choose not to read it when they sign up and are then surprised when their credit card is later charged. Reviews showcase a range of experiences, from significant health improvements to concerns about digestive reactions and product pricing. While some dogs might thrive on Ruff Greens, others might not react as favorably. Therefore, it's important to consider these factors before deciding to purchase their products.
