I went to the link and it is a statement and not research. Where is the research that says that 2% is ok?? I prefer this research article http://www.lowchensaustralia.com/health/skeletaldisease.htm.Tazman- Not at all, in studies they say anywhere from 1%-2% is acceptable in large breed puppies. They say giant breeds (Great Danes, Irish Wolfhounds) should be on the lower end of the spectrum. Seeing that my dog is not going to be a Giant breed I don't see 1.7% (max) as an issue as it falls in the parameters.
