Taste of the Wild is definitely better than California Natural, and there is no need for transitioning from a 1 star to a 3 star to a 5 star--go straight to the 5 star. Take it from someone who researched food last year until she almost was so beside herself she had almost snatched all her hair out! lol Ziwi Peak is going to be one of the best foods you can feed her. Ziwi Peak is dehydrated raw. Most stores don't sell it. You usually have to order it online, and it will be delivered to your home. It is not much more expensive than other dog foods especially for the small amount that is fed, and like Dee said-cheaper in the long run for your savings in heath benefits for your dog. If you do not choose Ziwi Peak, Acana is a great 5 star dog food as well as Fromm. I prefer Acana Limited Ingredient Diet food personally. Usually, to get a dog food with all the ingredients you would want and none that you wouldn't and manufactured by a company that has not had recalls, you have to order your food online. It is very hard to go to your local pet store to find this unless it is a specialty pet store. Again, this is just my opinion based on much research. BTW, Taste of the Wild is made by Diamond Pet Foods which had many recalls last year, and had had recalls in years past.
Life is better because I have a friend like you.
