really? we switch pupps to raw as soon an humanly possable, its MUCH better for their growth, if I compare moth my BCs one who grew up on kibble and one who was started on raw at 7 weeks the builds are very differnt, and its not hereditary, there is not one single dog in Happys entire pedigree that has a structure that even remotly resembles hers. Misty is smaller, better filled out, better muscled and had an overall better growth rate. Happy was not switched till around 6 months, she is tall, lanky, and if I shaved her she would pass for a greyhound lol she grew in huge sprurts, about 3 inches a week lol
