Every Ingredient Matters & Ingredient Quality and Purity Is Crucial to the Long Term Health of Your Furry Family

In the book, The Forever Dog, Dr. Karen Becker and Rodney Habib instruct pet parents to use a "chemical free pet shampoo".

Excellent advice and we fully agree, but what does that mean?

Unfortunately, with no regulations in the pet grooming industry and no regulations regarding the use of the words "natural" and "organic"
buying a pet shampoo without synthetic ingredients can be really confusing. 

In 2015, 4-Legger developed the first (and only) pet shampoo ingredient database to help you navigate the confusing world of ingredients found in dog shampoo. 

In 2021, we greatly enhanced the database as a stand alone website.

We don't want any pet parent to be duped like we were.

Ingredient rankings are our opinions of the safety of ingredients based on a review of the literature and safety recommendations. We do not review products. We have no way of knowing the concentrations used by manufacturers or the quality and purity of the ingredients. In cases where purity may be a factor we have erred on the side of caution asking ourselves the question, "Would I use this on my dog?"  This database is always "in progress" as rankings may change as new information is available. We do manufacture and sell 4-Legger, a true all natural and organic dog shampoo (with options for cats, small animals, etc) that we recommend but we also feel pet parents should assess ingredients themselves and choose the products they are comfortable using on their furry family. 4-Legger assumes no responsibility for misuse of the information presented herein.
