Hi there and you're very welcome to Cavaliertalk! I'm not sure if you got the chance to look at the site, but there is a section in the Health and Diet that may be of help to you. You can find it by clicking here: http://www.cavaliertalk.com/forums/f...and-diet-forum
Don't worry about if she is a bit skinny, my Belle was the same way and now she's 'pleasantly plump', which is a bigger worry than being skinny. Have you wormed your puppy yet?
