Is 4health a good enough dog food?
I've posted several questions about dog food previously...Originally, my mom had all of our dogs on Ol Roy for years. With my job, and actually making my own money, and already knowing that it was not a good dog food, wanted to put them on something better.I checked out walmart and got Purina Complete Natural...Only to learn that it is really not much better than Ol Roy.I figured out where our local Tractor Supply was, and went there today to look as some better brands Supplies Nylon of dog food...I had been research Blue Buffalo, and decided I'd get that if they had it in stock all the time. Well, they had one bag of adult left... And I need food for both a puppy and two full grown (1 year old and 11 year old) golden retriever and a lab.Not knowing much about other brands I started checking prices and flipping over bags to read ingredients...I ended up purchasing 4Health puppy, and 4Health Adult Lamb and Rice formula.I was using dogfoodanalysis.com to check the rating of food, and can't find this one on there...Here is the links for them:http://www.tractorsupply.com/pet-care/dog-products/nylon-dog-collars/dog-food/dry-dog-food/4health-lamb-amp-rice-formula-for-adult-dogs-dog-food-18-lb--5149532http://www.tractorsupply.com/pet-care/dog-products/nylon-dog-collars/dog-food/dry-dog-food/4health-puppy-formula-dog-food-18-lb--5138507So, I'm not sure...What does everyone else think? It seems to be a good food, but the fact is, I am not sure myself...Thank you before hand for any imput!
