I guess I can answer Georgie weighs 4lbs
He has occasionally gone below 4lbs but I would say 4lbs is an ideal weight for him. I agree with Nancy free feeding up until 6 months to 1 year. After 1 year we feed about 1/4 cup grain free kibble twice a day with Greek yogurt and add a plain boiled chicken tender for his evening meal. We also give him carrots, apples with no skin and other grain free snacks.
