Season's greetings. I took my 15 month old pup to the vet,and after a glowing report,I fessed up about switching him to raw when he turned one year old. She told me to mix some kibble in with his raw diet. I was told that it's not good to mix raw with processed food because of the difference in digestion rates. My Vet told me this is a myth. I am nervous about mixing the two , and would sure like to hear some thoughts on the whole idea.... I give him a raw diet that I buy premixed with veggies,and add fish oil . he gets tripe with every meal.he also gets turkey necks,and boiled eggs two or three nights a week. thanks for your input in advance..
