I am actually pretty happy with the raw diet.  I dont think Petsmart carries the frozen raw, but they do carry Natures Variety raw boost.  Its high protein kibble and freeze dried raw, toy breed.  My pups love it.  I home cook 3/4 days a week, and have canned Natures Variety Instinct with varied proteins which I add to kibble on non cooking days.  They get yogurt and coconut oil every morning and thats a treat for them.  I take probiotics for myself, but was using the yogurt as a source for the babies.  I'll have to look into some of the ones I've seen mentioned here.  I give a daily vitamin supplement just to be sure I dont miss any bases...I also add flax seed meal to homecooked food, with veggies and an egg now and then.   This is working well for my guys, particularly Sunni, who had a ton of medical and digestive issues because of her medical condition.  I know she grew super fast, lol.  But she is perfectly lean and fit.  Shes just not a tiny Yorkie.  At 6 1/2 months she's been 10 lbs for 5 weeks now..the longest she's gone without a growth spurt.  Vet says her weight is ideal for her body proportions

  So I am giving my own feeding method...5 stars
