This is one of the most promising cancer prevention food and can be found in your spice rack. The active compound in turmeric is curcumin, which has been shown to prevent the growth or spread of cancer cells in many types of cancer. It does this by acting as an anti-inflammatory and antioxidant, and by encouraging cancer cell death. Although there are no studies in dogs that prove a clear cancer preventive function, there are many studies done in other species and with cells that clearly demonstrate curcumin’s efficacy against cancer cells. For example, a dose of 80 mg/kg body weight was effective in preventing induced cancer in guinea pigs. While this may not be directly relatable to dogs, it does show that only a small amount should be required. Next time you make a batch of dog treats, add a couple of teaspoons of turmeric to the recipe. You’ll add a new flavor for your dog to try and will boost his/ her intake of antioxidants.
