"I bought the Redmond Large scale for my 3 Golden Retrievers. As any one with goldens know, weight is an issue with them as they are very food motivated. Our dogs are age 4 years to 11 years and we do obedience and hunt test competitions with them, so it is important to keep their weight at the recommended level to avoid stress on the joints. The Redmond Scale is very easy to use and accurate when compared to my vets scale."
