Background: My middle aged-senior Chihuahua Lucy was rescued from a neglectful home where she was starved. She weighed 1.3 pounds when we rescued her and she currently weighs 2.3 pounds, but definitely should weight more around 3-3.5 pounds. She is still skinny. She is VERY picky! She won't touch kibble. She will eat wet food, but only once a day and teeny tiny amount. She won't eat treats. My mom made her some homecooked food (She put chicken noodle soup,chopped unseasoned baked chicken,peas,and carrots. Lucy LOVED it, and has been eating it TWICE a day! That is a first for her, she would never eat anything twice a day. I think i found the perfect food for her that she likes and will actually eat a decent amount of. My question is, is whats in it all that should be in it? What should I put in it? Does she need to be supplemented with anything else? If you feed home cooked food what do you put in it?
