Looking for suggestions on adding fat & protein to a diet. I switched foods this past Spring and am not caring for the the results so far. The food just doesn't have enough fat & protein content. I bought in bulk, so still have 12 bags left. I want to use up the remaining food as it was a big money investment. So, what do you think I can add on a daily basis to help with the fat & protein? It will probably take me a couple months to work my way through the remaining 12 bags so it needs to be something healthy. Mix in a performance or puppy diet?
