Hi Amawil05 –
Going grain-free would be a smart idea – grains are inflammatory (something you really want to avoid when dealing with arthritic dogs). I’m assuming that by “Nature’s Instinct” you’re referring to Nature’s Variety Instinct. I would go with Nature’s Variety Instinct over Taste of the Wild. Nature’s Variety Instinct is manufactured by a reputable company, Taste of the Wild is manufactured by Diamond, a company known for producing low quality products and having frequent recalls. If you aren’t already giving joint support supplements, I would start a natural supplement regimen as well. Glucosamine, chondroitin, MSM and hyaluronic acid are all great for maintaining the joints; you can buy these supplements individually or in whole food form – some whole foods that contain some of these components and that are known for promoting joint health are green lipped mussel, sea cucumber, velvet antler, shark cartilage and eggshell membrane. There are also numerous natural supplements you can give that have anti-inflammatory properties – omega 3’s (up to 300 mg. per 10 lbs.), turmeric, boswellia, yucca, bromelain and tart cherry.
