I have 6 dogs. They eat a 30lb bag of kibble in 10 days. I feed them a premium food that costs $41.00 per bag. I refuse to switch to a cheaper brand because I have done years of research into dog nutrition and feel that I am giving them what they need to be happy and healthy. Money is getting tight and so I am looking for healthy ways to supliment their kibble to make it go further. Now that my pullets are at laying age, I have been adding cooked eggs to the dog kiible. I have also been adding cooked oatmeal and pumpkin. The dogs love it, and it is helping to stretch the kibble but, I don't want them to have the same foods over and over because variety is good. Does anyone have any other ideas of things to add to the kibble to stretch it?
